| 00:07:20 | mallum | at least cvs is still up |
| 00:07:32 | mallum | anyone using savanah at gnu ? |
| 00:07:45 | Tangent | mallum : Not me |
| 00:32:44 | Tangent | hrm.. got an extra error now too |
| 01:23:32 | Niddix | Got my tuxscreen today.. yahoo |
| 01:32:06 | bhima | is installing linux on his tuxscreen right now. |
| 01:33:27 | Tangent | bhima : Did you use buildroot? |
| 01:33:43 | bhima | nope, havne't used that. was just gonna use their pre-built stuff. |
| 01:34:40 | Tangent | bhima : I'm using the pre-built stuff at the moment.. I can't get the buildroot stuff to work |
| 01:35:01 | Tangent | i.e. it didn't work first time, so I started watching Simpsons ephisodes instead |
| 02:11:02 | bhima | hrm. c F!all D!inferno.backup doesn't seem to actually work. |
| 02:15:28 | BZFlag | bhima: windows or linux? |
| 02:15:39 | bhima | windows, sadly. |
| 02:15:53 | BZFlag | the filesize will not change till the copy is complete, and windows seems to have issues. |
| 02:16:09 | BZFlag | I don't know anyone that got the windows backup to work. |
| 02:16:20 | bhima | ok, thanks. Do you think that I'll be able to safely install from Windows? |
| 02:16:35 | BZFlag | there are newer inferno images on SF anyway, the blob install should work. |
| 02:18:15 | bhima | great, thanks. I'm about to run off to another room with a 12v supply to unflash it. I'm sure I can get JTAG stuff if I need to, I'd just prefer if I can avoid it :) |
| 02:20:11 | BZFlag | yes. be sure that P/m with no 12v shows all 0s in the last column before flashing blob. |
| 02:27:49 | andersee | BZFlag: guess what? I had the SODIMM rotated wrong... Those extra wires connect to S0# and S1# on the SODIMM connector -- chip select lines. |
| 02:28:08 | andersee | BZFlag: I've updated my pics and webpage to reflect that |
| 02:35:19 | bhima | can you unprotect flash without running InfernoRemote? |
| 02:37:10 | andersee | is away: I'm busy |
| 02:44:27 | BZFlag | bhima: yes, but I would suggest InfernoRemote as it's tough to get power on while reading the screen on the other side, and you need InfernoRemote to install blob anyway. |
| 04:13:58 | andersee | BZFlag: I finally got apm working on my laptop. It was the agpart.o kernel module... |
| 04:14:15 | andersee | BZFlag: How was it that you make kbdrate run on resume? |
| 04:16:57 | BZFlag | had to load it or unload it? |
| 04:17:55 | BZFlag | put that in /etc/apm/event.d/ |
| 04:18:53 | andersee | bother. I need to fix my firewall to allow DCC. |
| 04:18:57 | andersee | Mind emailing that? |
| 04:19:30 | BZFlag | heh. ok. |
| 04:24:30 | BZFlag | sent |
| 04:33:02 | BZFlag | nite |
| 06:11:10 | bhimaji | hrm. sourceforge.net is down. thi sis annoying. |
| 06:12:00 | bhimaji | I followed the c D!blob F!all command thing. and it didn't copy blob over. |
| 06:13:30 | bhimaji | anybody around? and any idea what I am doing wrong? |
| 06:36:08 | cdm | hey all. |
| 06:36:17 | scanline | good morning |
| 06:37:33 | cdm | morning. |
| 06:40:05 | cdm | I hope to be able to get all the real schems for the TuxScreen next week sometime. |
| 06:42:30 | scanline | From Philips? |
| 06:44:10 | cdm | I can't say right now. In fact, I may never be able to reveal where I will be getting them from. |
| 06:44:11 | cdm | :) |
| 06:44:14 | cdm | I might even get source. |
| 06:44:26 | cdm | it may even be that I can't release them. |
| 06:44:44 | scanline | I see... |
| 06:44:44 | cdm | but between the QNXscreen project and me answering questions everyone will be benifit. ;) |
| 06:45:14 | scanline | As long as it benefits microwindows, PicoGUI, and X also ;) |
| 06:46:12 | cdm | hahahaha...I don't see how any of those things will benifit. More like "as long as it benifits Linux as well". |
| 06:46:35 | scanline | good |
| 06:47:40 | scanline | maybe this would fix the memory limitations? |
| 06:48:03 | cdm | which memory limits? The fact that it has very little of it? |
| 06:48:23 | scanline | Well, there are problems with using larger DIMMs in the Tux |
| 06:48:33 | cdm | I hope that the Linux efforts can benifit since we will be benifiting from thier efforts at first. |
| 06:50:19 | scanline | ick... it's almost 2 AM here... |
| 06:50:26 | cdm | yeah, 1:50 here. |
| 06:50:35 | scanline | 1:53 here :P |
| 06:50:39 | scanline | hehe |
| 06:50:47 | cdm | scanline: where you at? |
| 06:50:53 | scanline | Boulder, Colorado |
| 06:51:12 | cdm | cool. |
| 06:51:18 | cdm | what are you doing in Boulder? |
| 06:51:23 | scanline | college |
| 06:51:26 | scanline | where are you? |
| 06:51:34 | cdm | New Mexico, Albuquerque. |
| 06:51:38 | cdm | Wife is doing her PhD. |
| 06:51:47 | cdm | I tele-commute back to Canada. |
| 06:52:21 | scanline | ah. How is it in New Mexico? |
| 06:53:06 | cdm | it is nice enough - for America. ;) |
| 06:53:10 | cdm | drivers are terrible. |
| 06:53:24 | cdm | but the weather is nice and the cost of living is pretty low. |
| 06:53:31 | scanline | yeah. Not as bad as Italy though |
| 06:53:43 | cdm | so I don't mind being here for a couple of years until we head back to Canada (Ottawa probably). |
| 06:53:48 | scanline | I've heard some horror stories from friends who were on a trip to Italy, having to survive the traffic there |
| 06:53:49 | cdm | since QNX is in Ottawa. |
| 07:00:54 | scanline | me finds the QNXscreen home page |
| 07:02:36 | cdm | did ya? |
| 07:03:04 | scanline | not much there yet |
| 07:03:12 | scanline | how much of QNX do you have running on the Tux? |
| 07:04:12 | cdm | nothing ATM. |
| 07:04:18 | cdm | I am too busy with http://qnx.wox.org/ipaq/ |
| 07:04:19 | cdm | ;) |
| 07:04:23 | bhimaji | bac. |
| 07:04:26 | cdm | since that one is for work. ;) |
| 07:04:41 | scanline | yeah. I saw the screenshots from that |
| 07:05:08 | bhimaji | my aunt lives in albuquerque. seemed nice when I visited. |
| 07:05:33 | bhimaji | any ideas why blob wouldn't load on a tuxscreen? |
| 07:05:38 | cdm | scanline: Yeah - checkout the docs as well. ;) |
| 07:05:54 | bhimaji | I gave it the c command from an inferno session on windows. |
| 07:06:11 | bhimaji | and it didn't say it was erasing flash, but it seemed to complete successfully. |
| 07:07:26 | scanline | cdm: Nice. I don't have an iPaq though. Can you make QNX run on a Helio? ;) |
| 07:08:24 | bhimaji | does the window manager UI stuff on QNX scale well to a 320x240 screen? |
| 07:08:33 | bhimaji | Most X11 WMs and apps don't :) |
| 07:10:27 | cdm | bhimaji: Yes, very well. |
| 07:10:43 | cdm | bhimaji: We are designed to run on these systems. |
| 07:10:53 | bhimaji | cdm: cool. I look forward to that :) |
| 07:11:07 | bhimaji | <--- Newton user |
| 07:11:10 | cdm | bhimaji: sweet. |
| 07:11:13 | bhimaji | <--- PDA UI bigot :) |
| 07:11:45 | scanline | <--- PDA UI developer (willing to take suggestions :) |
| 07:11:49 | cdm | hahaha... |
| 07:12:17 | bhimaji | scanline: you should play with a Newton if you can. you might want to read through apple's big Newton UI guidelines document too :) |
| 07:12:17 | scanline | Though I've mostly had my head in the low-level stuff lately |
| 07:12:41 | cdm | bhimaji: Right now we are working on the PtWindowFrame hook to do all the things we want it to do. http://207.198.90.123/ipaq_bsp/users_guide.html |
| 07:13:03 | bhimaji | is lynx-only right now :/ |
| 07:13:07 | cdm | ;) |
| 07:13:35 | bhimaji | on an athlon 1.4GHz with 512MB of RAM :) |
| 07:13:47 | bhimaji | and a $10 used 14" monior. |
| 07:14:07 | bhimaji | need to find space to put one of my spare 21"s in here. I have lots of fixed frequnecy 21" monitors. |
| 07:59:23 | bhimaji | hrm. anybody have a 0.4 blob I can get? |
| 08:24:59 | scanline | bhimaji: There's one in the tuxscreen download directory |
| 10:43:45 | Tangent | <- c[_] |
| 11:07:46 | scanline | is away: sleep |
| 16:36:03 | irc | holas. |
| 16:53:29 | bhimaji | yawns. |
| 16:53:34 | bhimaji | 0 |
| 16:54:04 | bhimaji | wonders why there is an all-caps virtual terminal... |
| 17:08:44 | GoRK | greetings |
| 17:09:29 | AlHaz | nanoo nanoo |
| 17:11:38 | GoRK | what's been happening since thursday when i went out of town? trying to catch up here |
| 17:12:06 | bhimaji | so what'sup with the all caps virtual terminal? it confuses me! |
| 17:12:33 | GoRK | bhimaji: hrm you must have done something bizzare... log off and log back on to it |
| 17:13:23 | bhimaji | just rebooted, actually, and now it's gone. |
| 17:13:37 | bhimaji | it was bizarre - everything was caps, but it knew what it was supposed to be. |
| 17:13:47 | bhimaji | LS worked - but if you held down the shift key it didn't. |
| 17:14:16 | bhimaji | just also installed the microwin image. |
| 17:14:19 | bhimaji | very nifty. |
| 17:14:40 | GoRK | certain escape codes can tell the term to go all caps. i dont know for sure, but running reset or logging off and back on usually will fix it |
| 17:16:11 | GoRK | has anyone else built a shanip board? |
| 17:16:47 | GoRK | mine barely worked (only for recording) and someone from the list said that there were some unclear things (which i probably screwed up) that he had found |
| 17:17:07 | bhimaji | what does the shanip let you do? |
| 17:17:47 | GoRK | hook ucb1200 chip's audio in/out's to the DSP so you can play/record audio |
| 17:18:18 | bhimaji | oh, can you make the speakerphone work on this? |
| 17:19:23 | bhimaji | that sounds nifty. I should make those modifications. |
| 17:20:51 | GoRK | yes. i have written the code to make the telephone work with spacecoaster's dsp patch and cosmicpenguin wrote daemon hooks for it and scanline has written a gui phone app that uses it... so yes the speakerphone, callerid, mute, etc. and everything else on the phone currently work |
| 17:21:44 | GoRK | the only thing left is parallel set detect, hold button, remote dtmf detect, and other misc garbage |
| 17:24:49 | bhimaji | cool! |
| 17:24:56 | bhimaji | where canI get this stuff? :) |
| 17:25:09 | GoRK | you cant get binaries yet. all the sources are in cvs |
| 17:25:21 | bhimaji | needs to work on his web-based voice mail system again. |
| 17:25:28 | GoRK | hopefully ill get a new picogui image out with all of it again |
| 17:25:32 | bhimaji | previously it was based on a Macintosh with a GeoPort telecom adaptor. |
| 17:25:56 | bhimaji | (software modem thing. not one of these wimpy half-software modems. this one was basically an audio in/out to the phone line device) |
| 17:29:24 | GoRK | GPSFan_away: in your shanip schematic, you list all the "1-10" uF caps as 10uF.. I built this board with some 4.7uF caps and it doesnt really work. could that be it? |
| 17:29:42 | GoRK | GPSFan_away: I also built it on a breadboard, so i could have screwed something also |
| 17:31:15 | GoRK | oh hmm i know what i did wrong.. the pcmcia jumper has to be connected even if youre not using the 5V pcmcia hack. no wonder i got no sound output |
| 17:31:21 | GoRK | wires it up |
| 17:35:19 | SpaceCoaster | GoRK: well, what happened? |
| 17:35:33 | GoRK | gettin ready to boot |
| 17:35:37 | GoRK | who else made this board? |
| 17:36:09 | SpaceCoaster | I haven't seen anyone else do it |
| 17:37:00 | GoRK | kurt mahan... who is that on irc? he posted to the list that he made one |
| 17:37:21 | SpaceCoaster | ooops hold on I might have a log |
| 17:38:31 | SpaceCoaster | is he ProtWork? |
| 17:38:38 | GoRK | dunno |
| 17:40:08 | SpaceCoaster | no sorry can't find anything |
| 17:40:09 | GoRK | im not confident that i soldered onto the right pads |
| 17:40:19 | GoRK | the images are not clear at all |
| 17:41:00 | SpaceCoaster | I think you need GPSFan |
| 17:41:04 | GoRK | maybe gpsfan's schematics are a little better.. he took his versioning system down.. the shanip shcemes say version 0.6 |
| 17:41:18 | GoRK | which afaik means incomplete or something.. and it's a simple circut, so... |
| 17:41:48 | | gpsfan was last seen on #tuxscreen 18 hours, 45 minutes and 4 seconds ago, saying: off to dinner... [Sat Oct 27 23:56:44 2001] |
| 17:41:48 | GoRK | ibot seen gpsfan |
| 17:41:55 | GoRK | hrm |
| 17:42:01 | SpaceCoaster | some people talked about contradictions, pictures not matching schematics etc |
| 17:42:15 | bhimaji | can linux turn the screen off? |
| 17:42:48 | GoRK | SpaceCoaster: yes that is the problem that i am having... the mofo doesnt work |
| 17:43:08 | GoRK | SpaceCoaster: and i thought i built it from the pictures |
| 17:43:34 | SpaceCoaster | which should be correct |
| 17:43:50 | bhimaji | last night there was some discussion, and at least one of the people thought that there was disagreement about which transistor was which in one place. |
| 17:44:16 | SpaceCoaster | is that for the pcmcia mod? |
| 17:44:21 | GoRK | you can't see very well where the wires in the photos go... the black wires are hard to see and you can't really tell which pads some wires solder to |
| 17:44:35 | GoRK | that must be for the pcmcia mod. afaik it's the only one that uses a transistor |
| 17:45:25 | GoRK | well... i guess im going to go make this board so i can be sure about my circut |
| 17:45:50 | GoRK | the pcb artwork pretty much has to be right |
| 17:46:11 | SpaceCoaster | how do you make the pcb? |
| 17:46:42 | bhimaji | after the PCMCIA mod, can you still use 3.3v cards as well? |
| 17:46:44 | GoRK | i use rub-on masks . it's really very easy |
| 17:47:27 | bhimaji | needs to start making some UV etched boards. |
| 17:47:35 | GoRK | bhimaji: yes the 5v mod only affects the bottom slot. you can use 3.3v cards only in the top one still and you can use 3.3v cards in the bottom slot also if you turn the 5v off |
| 17:47:37 | bhimaji | found an old EPROM eraser (ie: UV exposure thing) |
| 17:47:40 | GoRK | but it's a manual switch |
| 17:47:55 | bhimaji | ok. so you'll kill it if you put a 3.3v card in the bottom slot? |
| 17:48:32 | GoRK | doubtful. most of the pcmcia cards that we are using that are 3.3v will also work at 5v |
| 17:48:41 | GoRK | but |
| 17:48:48 | GoRK | it's not a certain thing |
| 17:49:19 | GoRK | i think cards are supposed to request which voltage they want |
| 17:49:50 | bhimaji | do CF to PCMCIA adaptors have voltage regulators in them? |
| 17:49:57 | bhimaji | I'm doubtful they do... |
| 17:50:10 | GoRK | i think that the cf spec requires cf cards to tolerate 5v |
| 17:50:34 | bhimaji | yeah, that's what I was thinking. |
| 17:50:51 | GoRK | imo you'd only do the mod if you had a specific card you needed to get working in the phone.. if you only want to use CF stuff, then why would you do the mod in the first place? |
| 17:50:57 | bhimaji | wants a 32MB CF card and a WaveLAN card in hs device :) |
| 17:51:19 | bhimaji | I might need two 5v cards. Ethernet plus wavelan. |
| 17:51:37 | GoRK | use cf ethernet |
| 17:51:38 | bhimaji | I'm going to use a tuxscreen for a wavelan base station. |
| 17:51:47 | GoRK | 2 5v cards is probably not going to happen... |
| 17:51:47 | bhimaji | cf ethernet is expensive. |
| 17:51:58 | bhimaji | why wouldn't two be possible? |
| 17:52:27 | GoRK | probably there is not enough room to get the extra components in... plus the top slot is soldered directly to the main board |
| 17:52:58 | GoRK | you'd have to do 2 of the 5v mods ... one for the top slot and one for the bottom one |
| 17:53:41 | bhimaji | oh. I'm fine with two mods. and I can do SMT rework. |
| 17:53:57 | bhimaji | I managed to get 128MB into an ipaq :) |
| 17:54:08 | GoRK | well then you are probably good to go. heh |
| 17:54:28 | GoRK | ouch 128mb... i'd like to have one of those to compile on |
| 17:54:48 | bhimaji | you might wanna try the handhelds.org skiffcluster. |
| 17:54:58 | bhimaji | but, yeah, compiling is one of the reasons I did that :) |
| 17:54:59 | GoRK | they only have 32mb and no swap though |
| 17:55:19 | bhimaji | ahh. ouch. |
| 17:55:25 | GoRK | i was trying to get perl compiled on them a few weeks ago.. it didnt work |
| 17:55:32 | bhimaji | is going to enjoy coda on his ipaq. |
| 17:55:47 | GoRK | somene gave me an account on a netwinder with 64mb and swap which worked fine |
| 17:57:08 | bhimaji | have you tried a cross-compiling toolchain? |
| 17:57:20 | GoRK | perl is almost impossible to x-compile |
| 17:57:57 | GoRK | it can be done but unless you have infinite knowledge of the perl build system you still have to run a ./config.sh natively |
| 17:58:15 | bhimaji | mmm, ok. icky. |
| 17:58:25 | bhimaji | is actually working on an arm emulator for another project. |
| 17:58:34 | bhimaji | that might be nifty for cross compiling. |
| 17:58:39 | bhimaji | though it's not going to be high performance. |
| 17:59:04 | GoRK | and a program called 'miniperl' gets built to bootstrap the compile.. and it shares object files with the final perl binary, so miniperl really has to be compiled for the target arch also |
| 18:00:00 | GoRK | but in answer to your earlier question, for most things i use emdebian's release of gcc-2.95.2 for arm targets |
| 18:05:49 | GoRK | and who was it who was going to hack the ceiva's?.... i got mine and have some ideas on where to start and scans of the board in it |
| 18:07:13 | bhimaji | I don't like big, complex build environments. have you ever used cons as a built tool? |
| 18:07:37 | GoRK | nope havent even heard of it.. what is it |
| 18:09:32 | bhimaji | it's a perl-based build tool that is very nifty. |
| 18:09:38 | GoRK | ah |
| 18:09:44 | bhimaji | it lets you build very large projects easily. |
| 18:09:51 | bhimaji | and it doesn't recompile anything it doesn't need to :) |
| 18:10:07 | bhimaji | we use it at work. large, complex codebase targetted towards multiple CPUs. |
| 18:14:31 | collord | GoRK: prpplague is the other ceiva dude... |
| 18:15:37 | GoRK | collord: that's what i thought.... anyway i know the frame dials in and will reconfigure its local number... it should be pretty easy to fake a connection and reconfigure it to dial into a pbx extension or something.. and then............ oooh yeah :) |
| 18:17:32 | GoRK | hmm you cant subscribe to the service in any increment smaller than 1 year |
| 18:18:12 | bhimaji | can you make the tuxscreen turn its LCD off or adjust the backlight? |
| 18:18:21 | GoRK | bhimaji: yes |
| 18:19:49 | collord | GoRK: you think they designed it to receive s/w updates over the phone? |
| 18:20:04 | GoRK | collord: what? the ceiva frame or the tuxscreen? |
| 18:20:16 | collord | GoRK: ceiva (sorry) |
| 18:21:10 | GoRK | collord: probably.. i know they did do an update to it where it will hold 20 pictures instead of just 10... dont know if that was a memory upgrade or a software upgrade to support higher compression or something |
| 18:21:13 | bhimaji | gork: cool. how do you do that? :) |
| 18:21:42 | GoRK | bhimaji: currently it's implemented via ioctl's to /dev/ucb1200-ts but in later kernels it will be implemented differently |
| 18:22:48 | GoRK | collord: of course that software change could have been entirely on ceiva's end with an optimized encoder or something.. the pictures are supposedly jpeg on the frame |
| 18:23:08 | bhimaji | gork: where would those be documented? |
| 18:23:38 | GoRK | bhimaji: no they aren't really.. you can read the source after you apply the patches (or use buildroot)... i can look em up for you though.. hang on |
| 18:24:36 | GoRK | ioctl 64 is backlight power (on=1 off=0) |
| 18:24:47 | GoRK | ioctl 65 is set brightness 0-0xFF |
| 18:24:55 | GoRK | ioctl 66 is get brightness |
| 18:25:08 | GoRK | ioctl 67 is set contrast 0-0xFF |
| 18:25:16 | GoRK | ioctl 68 is get contrast |
| 18:25:29 | bhimaji | thanks! |
| 18:25:33 | bhimaji | makes notes. |
| 18:27:09 | SpaceCoaster | GoRK: I think the brightness/contrast changed to be native values i.e. 0..7 and 0..63 |
| 18:29:05 | bhimaji | ahh, so the default stuff doesn't include those? |
| 18:29:30 | bhimaji | or do I just need to get the sourceto read ti? |
| 18:54:49 | wej | holas. |
| 18:55:34 | wej | how goes it nelson? |
| 18:59:39 | nelson | waj: yo estoy bueno. |
| 19:24:29 | GPSFan | GoRK: did you fix your problem? you had a question on the shanip board shchmatics. |
| 19:25:57 | SpaceCoaster | GPSFan: hi, GoRK has gone to make a pcb! |
| 19:26:26 | SpaceCoaster | GPSFan: wanna talk memory? |
| 19:27:08 | GPSFan | woooo! that's nice, did you catch the problem on the 5Vpcmcia mod where the schematic sketch shows D2 in the wrong position? |
| 19:27:57 | SpaceCoaster | no, I was staying away from that stuff until it was given the general all clear |
| 19:29:07 | GPSFan | good, the schematic sketch will lead to frying D2 & T1, the bottom sketch is correct but hard to follow. |
| 19:29:40 | SpaceCoaster | GoRK: is doing the audio board |
| 19:30:29 | SpaceCoaster | GPSFan: ok to talk memory issues? |
| 19:30:31 | Lenolium | So, do we have some real plans for doing the PCMCIA-5V yet? :) |
| 19:32:08 | GPSFan | Sure, I did a seconv version of the audio board schematic, and moved the current revisions to the schematic wiki page, where it belonged. The second round schematic is closer to being correct, but I had to trace the Lucent PCB picture, and ther3e may still be some errors. |
| 19:32:37 | GPSFan | like inmy typing ;>P |
| 19:32:52 | SpaceCoaster | GoRK: saw your 0.6 version |
| 19:33:24 | GPSFan | that is the newest... |
| 19:33:46 | SpaceCoaster | GPSFan: ok memory, I have a cunning plan... |
| 19:34:23 | GPSFan | ok, Baldrick, what is your cunning plan??? |
| 19:35:44 | SpaceCoaster | GPSFan: each of the ARM machines, except the shannon, tweaks the memory map in Linux. An example is linux/arch/arm/mach-sa1100/brutus.c |
| 19:36:11 | SpaceCoaster | It sets the banks of memory to hardwired values. I suggest we do the same. |
| 19:37:28 | GPSFan | SpaceCoaster: the major banks of DRAM are defined by the SA1100 architecture. C0000000, C8000000, D0000000, D8000000. |
| 19:37:47 | SpaceCoaster | The cunning part is that we load at d0000000 which has enough memory in both situations |
| 19:38:42 | GPSFan | Ah, BZ commented that loading at other than C0000000 would take a lot of work. |
| 19:40:58 | GPSFan | SpaceCoaster: so how much work is it really? |
| 19:41:18 | SpaceCoaster | GPSFan: ho hum, it appears to be configurable but I tried it and it didn't work |
| 19:41:59 | GPSFan | SpaceCoaster: how far did it get? |
| 19:42:42 | SpaceCoaster | It did the Uncompressing Linux and all the dots. Then nothing |
| 19:43:34 | SpaceCoaster | Do you know how the uncompressing works, how does it shuffle the kernel around? |
| 19:44:07 | GPSFan | SpaceCoaster: maybe it had trouble with DRAM at C0000000, that could be disabled in BLOB, so all there would be is 16M at D0000000, and 16M at D8000000. |
| 19:44:44 | GPSFan | I don't know what happens between the final uncompressing dot and the first message printed out. |
| 19:44:55 | SpaceCoaster | Well I am trying it with the 8+8 and with the first 8 disabled in blob, blob just reports d0 and d8. |
| 19:45:18 | GPSFan | Good starting point. |
| 19:46:38 | SpaceCoaster | I thought it shouldn't have problems with memory registers etc. |
| 19:50:04 | SpaceCoaster | maybe an uncompress kernel would be better? |
| 19:50:47 | GPSFan | If ther is room in the flash, try it. then you would know the uncompressing isn't an issue. |
| 19:51:50 | SpaceCoaster | I will compile up a tiny kernel. |
| 19:54:57 | GPSFan | SpaceCoaster: has anyone developed a version of blob that will allow booting off a compact flash card? |
| 19:55:36 | SpaceCoaster | not blob but I saw discussions for the ipaq bootloader |
| 19:57:33 | GPSFan | it would have know about filesystems, and of course would be bigger than the current blob, but might be very usefull for kernel development. |
| 19:58:26 | SpaceCoaster | even better would be tftp for network boots. |
| 19:58:52 | GPSFan | that too would be a great development tool. |
| 19:59:36 | SpaceCoaster | but I see how much junk is in the pcmcia support and it puts me off. |
| 20:01:02 | GPSFan | is some of that for hot plugging, all that would be required for blob would be to see if a card was present and set the interface for ATA mode. |
| 20:03:08 | SpaceCoaster | what does the ATA mode look like, disk, memory, i/o port? |
| 20:04:13 | GPSFan | On the Tux, I don't know, but the CF in ATA mode looks like an IDE disk. |
| 20:04:53 | GPSFan | so blob would need to drag an IDE driver along with it. |
| 20:10:35 | GPSFan | bbiab... |
| 20:23:28 | GPSFan | back... |
| 20:24:11 | SpaceCoaster | hmm, an uncompressed kernel just prints Starting kernel ... |
| 20:24:29 | GPSFan | even in the 8 + 8 config? |
| 20:25:12 | SpaceCoaster | yeah, with it loading at d0 |
| 20:26:13 | GPSFan | bur works loading at c0? |
| 20:27:16 | SpaceCoaster | don't sure, that needs a different compile |
| 20:28:19 | SpaceCoaster | the uncompressing linux comes from header code glued onto the vmlinux, so we are executing the downloaded code |
| 20:29:07 | SpaceCoaster | when it is compiled it generates a piggy.gz, just realised it is "piggy in the middle", has a header and trailer glued onto it. |
| 20:30:32 | GPSFan | piggy.gz, does that imply the the middle is compressed? |
| 20:31:17 | SpaceCoaster | sorry that was the compressed version, the uncompressed doesn't do that |
| 20:31:34 | GPSFan | oh ;>0 |
| 20:33:03 | GPSFan | so we know that code will execute at d0, there is something in the kernel that doesn't like to be there, despite it being a configurable parameter. |
| 20:34:04 | SpaceCoaster | indeed, it's very early on too, no I/O |
| 20:34:31 | GPSFan | would it be useful to re-compile for c0 and do a diff between the two binaries? |
| 20:35:04 | GPSFan | no I/O from the kernel, but the header prints something. |
| 20:35:54 | SpaceCoaster | indeed, I wonder where it decompresses it to? |
| 20:36:59 | GPSFan | is there such a thing as a kernel debugger? |
| 20:37:41 | SpaceCoaster | indeed there is, never used it |
| 20:37:59 | GPSFan | maybe now is a good time to start? |
| 20:38:15 | SpaceCoaster | :-) |
| 20:38:30 | SpaceCoaster | downloading uncompressed kernel compiled for C0 |
| 20:40:03 | SpaceCoaster | hmm, an uncompressed kernel doesn't run either! |
| 20:40:23 | GPSFan | that is actually good, I think. |
| 20:43:43 | SpaceCoaster | hmm might have trimmed it down too much, too out the console! |
| 20:44:17 | SpaceCoaster | s/too out/took out/ |
| 20:45:13 | GPSFan | oops, stdout too i presume. |
| 20:45:53 | SpaceCoaster | guess so, I lost my tiny config from yesterday, so I started again, from the non-working direction. |
| 20:49:42 | SpaceCoaster | GPSFan: ok, still no serial ports but the compressed tiny kernel at C0 outputs to the LCD |
| 20:50:20 | GPSFan | did you change anything, or just look at the LCD? |
| 20:51:14 | SpaceCoaster | I enabled the frame buffer |
| 20:51:42 | GPSFan | ok, maybe see what happens with a d0 compiled one... |
| 20:51:48 | SpaceCoaster | the uncompressed still does nothing, ok over to the d0 version. |
| 20:53:41 | SpaceCoaster | I had disabled the serial ports too, doh |
| 20:53:51 | GPSFan | ;>)) |
| 20:54:32 | SpaceCoaster | glad I'm not being paid to do this :-) |
| 20:56:36 | SpaceCoaster | :-( the tiny kernel, compressed at D0, just prints the booting the kernel message and I saw the FB support being compiled in! |
| 20:58:22 | GPSFan | ok, so we ahve 2 kernels, c0, & d0, one works (sort of) one doesn't, is it possible to do a diff on the binaries to see how different they are? |
| 21:02:17 | SpaceCoaster | It's the compressed one that works, so we need to diff the file used to generate piggy.gz |
| 21:02:49 | GPSFan | yep. |
| 21:03:20 | SpaceCoaster | hmm, it's just the vmlinux, as you would expect |
| 21:04:05 | SpaceCoaster | 10823 bytes different |
| 21:04:14 | GPSFan | out of how many? |
| 21:04:26 | SpaceCoaster | 769360 |
| 21:04:54 | GoRK | hello |
| 21:04:58 | GoRK | no i didnt make the pcb yet |
| 21:05:04 | GPSFan | hi |
| 21:05:13 | GoRK | but my question had to do with capacitor sizes.... |
| 21:05:35 | GoRK | the caps listed 1-10uF... do those all need to be 10uF? |
| 21:06:04 | GPSFan | oh, I just used 10uf as a placeholder, the actual value may or may not be important. |
| 21:06:41 | GPSFan | this is audio, as long as it is big enough to pass the low freq's you want it's ok. |
| 21:06:54 | GPSFan | (should be that is) ;>) |
| 21:07:15 | GoRK | so using 10uF might be better bet than using 4.7uF to start testing w/ |
| 21:07:16 | SpaceCoaster | GPSFan: most of the differences are 0xd0 and 0xc0 |
| 21:07:24 | GoRK | that was a question, sorry... |
| 21:07:46 | SpaceCoaster | yeah / is a question mark, almost |
| 21:08:24 | GoRK | what are you doing diffs of here? |
| 21:08:34 | SpaceCoaster | binaries |
| 21:08:34 | GPSFan | GoRK: yes if you have 10's them use them, if you have 4.7's they would probably work. after it is built, you could do a frequency sweep to see how the low end rolled off, and adjust. |
| 21:09:17 | GoRK | GPSFan: yeah im using a bunch of 4.7's right now and getting horrible sound on recording. (this is on the breadboard and i think it's screwed up also |
| 21:09:27 | GPSFan | SpaceCoaster: what are the non c0/d0 ones? |
| 21:09:39 | GoRK | GPSFan: i am also unsure of the pins i have soldered to on the mongoose connector |
| 21:09:42 | SpaceCoaster | GPSFan: it's likely to be something that should be different but isn't |
| 21:09:55 | SpaceCoaster | a lot of 63 --> 62 |
| 21:10:15 | SpaceCoaster | that's octal |
| 21:10:26 | GPSFan | yeah, that's prpbably right, as luck would have it. |
| 21:10:49 | GPSFan | octal? you ever work at DEC? |
| 21:11:04 | GoRK | what are the differences between these kernels? not the binary differences but the functional differences? |
| 21:11:16 | SpaceCoaster | 33 -> 32 hex, no but the cmp program was written for a PDP11 |
| 21:11:36 | GPSFan | ;>) |
| 21:11:56 | SpaceCoaster | fully backwards compatible with the 1970s |
| 21:13:10 | GPSFan | GoRK: what kind of horrible sound? feedback like, distortion? |
| 21:13:49 | GoRK | we should write to softmodem.technicalsupport@philips.com .... since this modem is only v.34 capable and not v90 we might get them to release some code for making it work :) |
| 21:13:55 | GoRK | GPSFan: yeah it's distorted |
| 21:13:57 | SpaceCoaster | GoRK: I am attempting to generate a kernel which loads and runs at d0000000, we have at least 4m of memory at this address in both 8+8 and 8+32 configurations. |
| 21:15:06 | GoRK | SpaceCoaster: ahh so that we bypass the 8x1M banks entirely? |
| 21:15:39 | GoRK | SpaceCoaster: you also have to modify the blob jump to that address, right? |
| 21:17:42 | GPSFan | GoRK: it sounds like something is being over-driven. How about playback of sounds recorded some other way. |
| 21:17:45 | SpaceCoaster | GoRK: I can jump to the kernel from blob, it runs the decompression code (which is in a header on the kernel) but nothing after that. |
| 21:18:45 | SpaceCoaster | GoRK: most of the other ARM machines run a routine called fixup() to fixup the memory map after the bootloader, we don't, yet |
| 21:19:22 | GoRK | GPSFan: i think my circut is messed up on this breadboard, so i'm just waiting on building the pcb |
| 21:19:29 | GoRK | brb |
| 21:19:52 | GPSFan | GoRK: does playback work at all? |
| 21:20:47 | GPSFan | SpaceCoaster: what does fixup do? does it play with the MMU? |
| 21:21:53 | SpaceCoaster | It hacks the memory map passed in from blob |
| 21:23:12 | SpaceCoaster | GPSFan: the memory map is the table that we see displayed in blob. |
| 21:23:18 | GPSFan | SpaceCoaster: is the source anywhere I can look at it? |
| 21:23:37 | GPSFan | No, I don't have a build environment. |
| 21:23:45 | AlHaz | I'm surprised the modem is implemented just with the ucb1200 and not with the dsp |
| 21:24:26 | GoRK | GPSFan: i can see some voltages on my meter, but i dont hear anything. i think i probably just have a connection to the board at the wrong place or something |
| 21:25:03 | GPSFan | GoRK: did you build it from my schematic, and if so what version? |
| 21:25:35 | GoRK | GPSFan: im building it directly from their pcb artwork |
| 21:26:00 | GoRK | i built the breadboard out of a schematic i drew from their pcb artwork :) |
| 21:26:09 | GoRK | so... another potential problem |
| 21:26:59 | GPSFan | GoRK: the first schematic I drew from their artwork missed a few connections that were not readily visable. look at my schematic rev .6 it has where to connect all the wires. |
| 21:27:13 | GPSFan | to the Tux boards. |
| 21:29:53 | SpaceCoaster | GPSFan: can you download stuff and apply patches? |
| 21:30:28 | GPSFan | never tried, remember I'm not a programmer, just curious. ;>) |
| 21:31:10 | SpaceCoaster | is eating |
| 21:53:34 | GPSFan | GoRK: have you looked at the 5V pcmcia mods yet? |
| 22:31:28 | sb-- | what will the DSP code do |
| 23:05:46 | wej | buh |
| 23:05:53 | wej | has *anyone* gotten any 802.11 working? |
| 23:06:07 | bhima | I might tonight! :) |
| 23:07:24 | wej | seriously? |
| 23:07:27 | wej | using which card? |
| 23:07:39 | bhima | I'm going to be modifying it to do 5v and testing out a Lucent card. |
| 23:07:48 | wej | whoah. |
| 23:07:50 | bhima | whenever the pizza finally gets here. |
| 23:07:52 | bhima | grrs. |
| 23:07:54 | wej | how'd you get your hands on the 5v mod? |
| 23:08:09 | bhima | it's documented in the wiki. |
| 23:08:16 | wej | has a linksys card, and a cisco aironet... |
| 23:08:19 | bhima | s/documented/linked from/ |
| 23:08:20 | wej | the aironet is a 5v |
| 23:08:31 | wej | that must be recent.... |
| 23:08:35 | wej | i'll take a look. |
| 23:08:35 | wej | brb. |
| 23:08:37 | bhima | yeah. |
| 23:16:24 | GPSFan | bhima: did we talk yesterday about the 5V mod? |
| 23:16:54 | bhima | gps: yeah, we did. |
| 23:17:24 | GPSFan | ok, was worried that you might wire it up like the schematic sketch... |
| 23:17:39 | bhima | gps: ahh. I didn't remember that there was a problem with that. |
| 23:17:42 | bhima | how do I wire it? |
| 23:18:02 | GPSFan | look at D2 and what happens when T1 in "on"... |
| 23:18:10 | GPSFan | sin/is |
| 23:19:00 | bhima | so what is the right diagram? |
| 23:19:03 | GPSFan | also look at the wireing diagram below and notice that the cathode of D2 goes to somewhere other than is shown in the above schematic. |
| 23:19:43 | GPSFan | the bottom. the cathode of D2 should be tied to 3-5V--PCMCIA Card Power. |
| 23:19:56 | GPSFan | the anode is going to 3.3V |
| 23:20:04 | GPSFan | in both places. |
| 23:21:14 | GPSFan | if the top were wired up, and T1 is "on" (as in when not resetting) you have a direct path from 3.3V through D2 & T1 to ground...Fry... |
| 23:25:20 | bhima | ergh. |
| 23:25:25 | bhima | that sounds bad. |
| 23:26:15 | GPSFan | it looks like a simple mistake when the schematic sketch was drawn. the wireing diagram shows D2 correctly... |
| 23:29:11 | GPSFan | off to dinner... |
| 23:29:16 | bhima | thanks :) |
| 23:39:14 | drclone | hello do i need special settings for xf86 when using a tft panel? |
| 23:40:05 | bhima | drclone: what hardware? tuxscreen? or other stuff? |
| 23:40:28 | bhima | some flat panels are just random monitors, others use a slightly different interace, some of them are really unique. |
| 23:40:37 | drclone | hardware:: erm some kind of tft screen on a laptop... |
| 23:41:07 | drclone | doesnt know exactly. there is no doc around. |
| 23:41:22 | bhima | on a laptop, usually you just need the right driver for the chipset. |
| 23:41:48 | drclone | well for the video card this already happened. (i think so at least) |
| 23:42:09 | drclone | i have a sis 630 chip, so xf86 4.1.0 supports it just fine. |
| 23:42:37 | bhima | ok, so what is the problem...? |
| 23:43:08 | drclone | if i set a higher resolutin than 8 bpp the screen stays black. |
| 23:43:14 | drclone | dont know why. |
| 23:43:33 | drclone | with 15,16 and 24 it doesnt works |
| 23:44:05 | bhima | do you have enough VRAM? Does it work with other OSs? |
| 23:44:35 | drclone | it works with windoze, and i have 16 megs of vram. |
| 23:44:45 | drclone | so it should be just fine. |
| 23:45:13 | bhima | hrm. odd. that sounds like you should search out device specific advice on google or various newsgroups :) |
| 23:45:47 | drclone | sounds good. i even dont know who produced this tft panels :))) |
| 23:46:07 | bhima | well, it's more likely to be a chipset thing than a tft thing. I believe. |
| 23:46:38 | drclone | you think so? whats your opinion, what should i try ?? |
| 23:47:04 | bhima | what I mean is- it looks like your chipset programming info is more important than the kind of TFT panel. |
| 23:47:18 | bhima | TFTs are usually quite passive devices. |
| 23:47:40 | drclone | i also thought this until now :))) |
| 23:48:29 | drclone | besides:: sis doesnt provide ANY kind of drivers for the chipset. |
| 23:49:54 | drclone | ah and something else:: when starting X in a resolution higher than 8bpp the screen turns kinda "green" after a while, and it seems, like some slime flowing around the panel .... really scary :)) |
| 23:50:16 | bhima | ick. sounds like you need the right config stuff. |
| 23:50:33 | bhima | but this really isn't something I am familiar with in practical terms, just theoretical :) |
| 23:50:39 | drclone | any idea? |
| 23:51:20 | bhima | get a Mac and run Darwin/OS X. Great support for the flat panels there :) |
| 23:51:30 | drclone | :))))))) |
| 23:51:35 | drclone | lol |
| 23:52:27 | bhima | seriously, you get good UNIX support on them :) |
| 23:52:31 | drclone | might be an idea... |
| 23:52:56 | bhima | plus, you don't get the "teensy company that popped up, prodcued a run of them, and disappeared" issue. |
| 23:53:02 | drclone | i know a friend has os X |
| 23:54:04 | drclone | well madrake should be ok too. |
| 23:56:10 | drclone | well ok thank you for all. |
| 23:56:39 | bhima | good luck. |
| 23:57:51 | drclone | bye |
