02:13.57 | Jag | LTSP is pretty cool |
02:14.22 | mastermnd | per someone elses suggestion I'm going to bring a tuxscreen to try and set that up as one of our clients at the meeting. |

03:03.39 | sorphin | today |
03:03.45 | prpplague | sorphin: what? |
03:03.49 | sorphin | 'my maxim samples ;p |
03:03.56 | MattSmith | I made the mistake of doing make clean or dirclean maybe... so now I'm missing tuxphone again. |
03:04.00 | prpplague | thats what i was about to say |
03:04.11 | sorphin | prpplague: sent me the wrong crap tho |
03:04.22 | sorphin | 'sent 233s (fine) and 225s instead of 235s |
03:04.36 | prpplague | MattSmith: hey how many lcd's have you got for the tuxscreen? |
03:04.41 | sorphin | heh, 225's cost $2.00 more, draw 2ma more, and are SOICs only |
03:04.54 | prpplague | sorphin: fun |
03:04.59 | MattSmith | prpplague: 2 |
03:05.09 | prpplague | sorphin: my pcb prototype stuff showed up today |
03:05.19 | prpplague | MattSmith: not using them for anything? |
03:05.28 | sorphin | prpplague: cool |
03:05.29 | prpplague | MattSmith: they are very sa friendlt |
03:05.41 | MattSmith | sa friendly? |
03:05.46 | sorphin | strongarm |
03:06.20 | MattSmith | well, I've just got the two tuxscreens - nothing else to attach to them.. unless you've got some ideas.. Maybe a display for in-car or something |
03:06.42 | prpplague | MattSmith: did you got headless? |
03:06.43 | MattSmith | I may get rid of the whole lot if I can't figure this stuff out.. |
03:06.44 | MonMotha | sorphin: they sent me a chip in SSOP even though I specifically requested DIP...I can't work with SSOPs...SOICs maybe (solder small wire right onto the pins), but not SSOPTs |
03:06.58 | prpplague | MattSmith: whats up? |
03:07.22 | sorphin | MonMotha: 14 pins |
03:07.27 | sorphin | *2 |
03:07.34 | MattSmith | prpplague: headless? I'm trying to add wireless-tools to the tuxscreen image - I'm not having much luck. I'm trying to turn them into ap's... |
03:07.45 | sorphin | MonMotha: better spacing than the arm ;) |
03:07.58 | MonMotha | sorphin: true...though still tough to work with |
03:07.59 | MattSmith | the phone part got hit by lightning, so it's either get this working, or get rid of them. |
03:08.08 | sorphin | MonMotha: these aren't bad |
03:08.26 | MonMotha | I just hope they don't send me a uCSP (chip scale) package |
03:08.44 | sorphin | hehe |
03:08.47 | MonMotha | which are basically ungodly small BGAs |
03:09.04 | sorphin | MonMotha: better warm up that toaster oven ;) |

03:17.18 | prpplague | ibot: tell MattSmith about prpplague |
03:17.47 | prpplague | MattSmith: let me know if you need some help |
03:19.17 | MattSmith | prpplague: I could use a little direction on what is required for a .mk file... and I need the tuxphone package source.. but anon cvs is down... |
03:19.59 | prpplague | MattSmith: you can read the info about the .mk from the buildroot info |
03:20.08 | prpplague | ibot: buildroot |
03:20.09 | | somebody said buildroot was a cool system for building embedded root file systems and can be found at http://uclibc.org/cgi-bin/cvsweb/buildroot/ or a heavily modified version used by the OpenZaurus project, or see oz buildroot |
03:20.24 | prpplague | let me check about the buildroot |
03:20.53 | sorphin | prpplague: sf cvs is disabled now, so.. |
03:21.08 | prpplague | MattSmith: you can get a base tar ball from http://www.tuxscreen.net/download/ |
03:21.55 | prpplague | MattSmith: that can get you started |
03:22.04 | prpplague | sorphin: whats up with sf? |
03:22.39 | sorphin | prpplague: from what russ said, too much load |
03:22.47 | prpplague | sorphin: i think i'm with ac about sf, we are putting tooooooo much confidencience and dependence with sf |
03:23.09 | sorphin | ac ? |
03:23.39 | prpplague | alan cox |
03:24.45 | mastermnd | MattSmith: I can send a current buildroot |
03:24.49 | MattSmith | prpplague: I'm a little past started... I've builtroot successfully - I'm not seeing any .mk file info in the buildroot area |
03:25.18 | mastermnd | look in buildrook/make |
03:26.22 | MattSmith | there's a bunch of .mk files - is there one in particular that is well commented or something? |
03:27.32 | mastermnd | don't think so, pick the one that's most similar to what your doing as an example, or the simplest looking one. |
03:27.58 | mastermnd | they're just like Makefiles |
03:28.32 | prpplague | MattSmith: one of the best to look at is the tinyx build |
03:28.51 | MattSmith | k |
03:28.57 | prpplague | MattSmith: the thing to remember is that all function needs to be seperated with a ; |
03:29.10 | prpplague | MattSmith: you can use alot of shell script functionality |
03:29.12 | MattSmith | mastermnd: except different |
03:29.37 | prpplague | MattSmith: what kinda project are you working on? |
03:29.59 | prpplague | MattSmith: btw, most every one is every familiar with what every one else is working on |
03:30.11 | MattSmith | um.... wireless access point.. |
03:30.19 | prpplague | MattSmith: makes it easier to get to the person that knows the most about the topic |
03:30.32 | prpplague | MattSmith: oops you already told me that |

03:31.40 | prpplague | ahh |
03:33.43 | MattSmith | I've done the 5v mod, got the driver loaded and working, I just can't modify the wireless cards settings without the wireless toolkit |

04:13.07 | sorphin | kergoth: in other news, my maxim parts showed, but one of the samples is wrong (225 SOICs instead of 235 dips), and the Z is still sleeping in the cradle ;p |
04:15.13 | kergoth | heheh |
04:16.51 | MonMotha | sorphin: how well do you think a USB mod for the tuxscreen would be received? think it's worth the hack value or should I not bother? |
04:16.54 | prpplague | ha, dextor's libretto is on |
04:17.04 | MonMotha | the hardware appears to be rather simple, but SA-1100 (and 1110) UDC is a pain to work with in software |
04:17.15 | sorphin | MonMotha: hmm |
04:17.28 | sorphin | MonMotha: i'd see what daveyboy thinks and/or tim |
04:18.00 | MonMotha | I can do some work on it (and we can steal from the ipaq people's usbf driver as I know it's GPL or maybe the zaurus one) |
04:18.34 | kergoth | word is the USBD stack from Lineo is a better design than usb-ether, but either would certainly do the job. |
04:18.40 | MonMotha | I'm looking at the fairchild USB1T11A line transceiver for hardware...should be pretty much direct connect to the SA-1100 UDC pins (though I need to confirm that) |
04:18.40 | prpplague | MonMotha: i'd love one for the hack kit, and the core module for the tuxscreen should be pretty close |
04:18.51 | MonMotha | prpplague: yeah, it should carry over fairly nicely |
04:19.08 | sorphin | MonMotha: :) |
04:19.41 | MonMotha | I should have asked Intel for a SA-1100 dev manual when I asked for the SA-1110 dev manuals |
04:20.23 | MonMotha | prpplague: well, once I get my SA-1110 manual I'll get started |
04:20.38 | prpplague | lol |
04:20.43 | MonMotha | 497 (or whatever it is) PDFs are a little inconvenient to read so I asked for it in dead tree form |
04:21.12 | prpplague | ahh, i have an old hp duplex printer for that purpose |
04:21.36 | MonMotha | well, they're free...you just have to wait for them to be shipped |
04:21.41 | MonMotha | and then you get nice binding and all |
04:21.51 | MonMotha | they don't ship them fast...UPS ground I think |
04:22.04 | MonMotha | I'm amazed at TI and fairchild with samples and shipping |
04:22.14 | MonMotha | TI ships UPS next day air, fairchild FedEx next day air |
04:22.36 | prpplague | MonMotha: hell, i got some crystal samples send fedex overnight red... |
04:22.42 | MonMotha | wow |
04:23.04 | MonMotha | code red is damn fast (I've seen times of under 8 hours for fedex red) |
04:23.12 | sorphin | MonMotha: and maxim, slowest 1st class i've ever seen |
04:23.17 | MonMotha | same day shipping...next best thing to a courier |
04:23.19 | MonMotha | sorphin: heh |
04:23.23 | sorphin | they picked my samples on the 7th :P |
04:23.48 | prpplague | MonMotha: you know its so strange that you can get chip samples free and quick, and you order an arm board and you have to pay >1k and wait forever |
04:24.06 | sorphin | prpplague: they're baiting you w/ the samples that's why |
04:24.07 | MonMotha | prpplague: yep :) |
04:24.18 | sorphin | prpplague: when they have your $ for the order, they make you wait |
04:24.52 | MonMotha | got some nice shift registers |
04:24.55 | MonMotha | very useful |
04:25.07 | MonMotha | sucks that RS doesn't have them |
04:26.50 | prpplague | RS is a shit hole these days |
04:28.46 | MonMotha | yes |
04:29.12 | prpplague | MonMotha: if you want to electronics these days you have to go all out and be a pure whore during the day to afford it |
04:29.29 | MattSmith | can anybody recommend a good irc client (not gui) ? |
04:29.57 | kergoth | irssi, bitchx |
04:29.59 | prpplague | MonMotha: in the last 6 months i've never been closer to understanding the mentality of stripers |
04:30.47 | MonMotha | prpplague: ??? |
04:30.59 | kergoth | prpplague: lol |
04:31.30 | prpplague | MonMotha: you see kergoth understands |

04:33.02 | prpplague | MonMotha: i.e. prostitue yourself out during the day for money |
04:33.37 | MonMotha | prpplague: ah, I was thinking too deeply |

18:29.35 | mattsmith | can't seem to find mkjffs |
18:30.11 | CosmicPenguin | mattsmith: it has to be in the buildroot, otherwise nothing would work |

19:22.12 | CosmicPenguin | yeah, your libc |
19:22.24 | CosmicPenguin | Did you build them with uclibc like the rest of the apps? |
19:22.50 | mattsmith | Hmmm... probably not |
19:23.15 | CosmicPenguin | mattsmith: you really gotta insert your app into the buildroot - otherwise stuff like that will happen |

22:04.13 | mastermnd | anyone with tuxscreen commit access here? |
22:07.17 | MonMotha6 | mastermnd: certainly. why? |
22:07.40 | MonMotha6 | I don't but I know Erik does, and some others too |
22:08.33 | mastermnd | I've got a line to add to busybox.mk |
22:08.55 | mastermnd | a clean buildroot wont make it past linux.mk without this line: |
22:09.05 | mastermnd | $(BUSYBOX_DIR)/scripts/depmod.pl: busybox-unpack |
22:09.14 | MonMotha6 | that would be erik |
22:14.30 | CosmicPenguin | mastermnd: send a patch to the Tuxscreen list |
22:14.56 | CosmicPenguin | I've got commit, but thats Erik's area of expertise |
22:15.50 | mastermnd | ok, what about zlib.mk? the way CFLAGS is defined it doesn't come out right. |
22:16.34 | CosmicPenguin | mastermnd: patches are always acceptable |
22:23.25 | mastermnd | "cvs diff -u <filename>" correct? |
22:25.49 | *** join/#elinux file (jwired@mctn1-2814.nb.aliant.net) |
22:30.20 | CosmicPenguin | No, do a normal diff - CVS diffs have issues |
22:30.27 | CosmicPenguin | diff -urN <original> <new> |
22:30.47 | CosmicPenguin | Or rather, diff -urN --exclude CVS <orignal> <new> |
22:30.49 | andersee | mastermnd: take a look at the latest here |
22:30.52 | andersee | mastermnd: http://www.uclibc.org/cgi-bin/cvsweb/buildroot/make/ |
22:31.01 | mastermnd | ok |
22:31.33 | andersee | mastermnd: I've made a _lot_ of updates that I've not yet merged back into the tuxscreen buildroot |
22:32.30 | MonMotha6 | andersee: does OpenSSL work now? |
22:33.03 | andersee | mastermnd: oops. Looks like I forgot to update the zlib cflags |
22:33.10 | andersee | MonMotha6: it works for me |
22:33.23 | MonMotha6 | andersee: nice...I know the tuxscreen one didn't last I checked |
22:35.44 | andersee | MonMotha6: Hmm. |
22:37.39 | mastermnd | are the .mk files pretty much drop-in compatible between the uclibc.org buildroot and the tuxscreen one? |
22:38.32 | andersee | mastermnd: for most of them yes. |
22:38.52 | andersee | mastermnd: For a few specialized one, like linux.mk, no |
22:40.14 | andersee | mastermnd: pcmcia is another one that would need a little bit of hand tuning. |
22:41.42 | mastermnd | ok, that's basically what I figured. |
22:41.56 | andersee | mastermnd: if you just grabbed buildroot from uclibc.org, you'll want to do a 'cvs up'. I just checked in a few little fixes, including the zlib cflags fix |

22:44.30 | mastermnd | the uclibc busybox.mk didn't help. I'm not sure if this is best fixed in busybox.mk or linux.mk, but it's easiest to fix in busybox.mk |

22:55.45 | file | talk to me... like lovers do |
22:55.49 | file | walk with me... like lovers do |
23:13.13 | MonMotha6 | ok, I really should learn more about analog electronics... |
23:13.55 | file | MonMotha6: hehe |
23:15.27 | MonMotha6 | file: well, I have a situation that there has to be a solution to, but I don't know it |
23:16.07 | MonMotha6 | I've got the output of a flip-flop cascaded to the input of another flip-flop to make a poor man's shift register, however I also have each set of outputs going to an address bus |
23:16.28 | file | lol |
23:16.32 | MonMotha6 | normally that bus is at 5V, but there is a situation where on pin has to be at 12V. I can tri-state the latches outputs, but the inputs are a problem |
23:16.41 | MonMotha6 | 12V is well outside the ratings on the inputs of these things |
23:17.01 | MonMotha6 | starting over? |
23:18.11 | MonMotha6 | there's no easy way around the problem that if I use cascaded shift registers (as I will have to...they don't make 24 bit parallel in-parallel out shift registers that shift 8 bits at a time), the input of one will be on the A9 pin of this PROM |
23:18.26 | MonMotha6 | and the A9 pin has to be able to be raised to 12V to get the manuf. ID |
23:18.52 | file | mmm |
23:18.54 | file | I dunno |
23:32.08 | ade|desk | MonMotha6: best way to do 12V to ttl is just a straight invert buffer, most can cope with high inputs (~15V) |
23:32.54 | ade|desk | and invert the invert of course |
23:32.56 | MonMotha6 | ade|desk: so basically just throw a buffer in between those two and let it handle the 12V? |
23:33.12 | ade|desk | should work |
23:33.20 | ade|desk | not cmos though |
23:33.20 | MonMotha6 | k |
23:33.52 | MonMotha6 | yeah, I may have to find a TTL one...fortunately all my parts are HCT so they can interface directly to a TTL part |
23:35.04 | ade|desk | HCT .. fast a useful ... but not here :/ |
23:35.18 | MonMotha6 | yeah |
23:35.26 | MonMotha6 | well, radio shack sells HCT parts |
23:36.20 | ade|desk | poo my browser just stopped :( |
23:36.38 | MonMotha6 | ade|desk: someone suggested jsut using a zener diode :) |
23:38.13 | ade|desk | that would work |
23:38.45 | ade|desk | just find one with correct break |
23:38.54 | MonMotha6 | 5V, right? |
23:39.02 | MonMotha6 | if it's over 5V, drop it to ground |
23:39.24 | MonMotha6 | damn, I'm actually going to have to do some calculations here :) |
23:40.22 | ade|desk | but (5~12)-->5V and below 3 -->0V yes ? |
23:41.11 | MonMotha6 | nono, the input that I'm protecting doesn't care when the 12V will be coming |
23:41.46 | MonMotha6 | what I have is an output hooked up to two inputs; one is a PROM, and the other is another flip-flop |
23:42.10 | MonMotha6 | when the 12V is applied, I'm attempting to read the Manuf. ID fromthe PROM, so the flip-flops are all disabled anyway and will be put back into a known state before being used again |
23:43.29 | MonMotha6 | I could just put a buffer on the A9 pin (the one getting hit with 12V) |
23:43.47 | MonMotha6 | the inputs will be tri-state when the 12V is applied, and the input of the flip-flop will be behind the buffer |
23:44.11 | ade|desk | ah right |
23:44.40 | MonMotha6 | I should probably do that anyway to protect all the inputs |
23:46.09 | Jag | Anyone here booted a cramfs off a falsh device? |
23:46.11 | Jag | flash even |
23:46.41 | ade|desk | why whats up ? |
23:48.02 | Jag | Can't get this one to boot |
23:48.16 | Jag | I'm trying it with Midori's cramfsboot bootloader |
23:48.26 | Jag | It doesn't seem to be co-operating |
23:48.43 | Jag | I don't think grub supports loading the kernel from a cramfs partition. |
23:48.49 | Jag | Nor syslinux |
23:49.28 | Jag | Hmm.. Perhaps I could put the kernel on a never actually mounted ext2 filesystem, and just have it mount the cramfs root.. |
23:50.54 | MonMotha6 | Jag: or just throw it on a raw partition |
23:51.07 | MonMotha6 | lots of stuff can boot that |
23:51.28 | Jag | So, just leave the kernel in a raw paritition 1, and dd the cramfs onto partition 2? |
23:51.37 | Jag | And then load grub or something in as the boot laoder. |
23:51.51 | Jag | Hmm.. grubs a bad idea since it wants it's stage 1.5 off a file system |
23:51.58 | Jag | syslinux would be the way to go I guess |
23:52.13 | MonMotha6 | why use GRUB? I'd think it would be darn simple to boot it at that point |
23:52.23 | Jag | It's accessed as an IDE device |
23:52.30 | MonMotha6 | in fact, on some arch's the kernel can boot itself at that point |
23:52.33 | MonMotha6 | like x86 on floppy |
23:52.36 | MonMotha6 | dunno if it can do it off a hdd |
23:52.44 | Jag | Not on a hd |
23:52.57 | Jag | But some minimal bootloader will do the trick |
23:53.17 | MonMotha6 | basically the kernel just needs to be copied to RAM and jumped to, right? |
23:53.19 | Jag | lilo perhaps, it can run just in the boot sector |
23:53.24 | MonMotha6 | there you go then |
23:53.40 | Jag | I'll give it a shot. Thanks |
