| 02:38.33 | ka6sox-office | hey jacques |
| 02:38.45 | ka6sox-office | wazzup? |
| 02:39.25 | jacques | I was wondering if you had any mpc824x bdi2000 config files I could look at |
| 02:39.33 | jacques | I need examples of flash chip config |
| 02:40.19 | ka6sox-office | no I don't unfortunately...we will in a month or so when we start working on the 8241 board we will be getting. |
| 02:40.33 | jacques | ah ok |
| 02:41.46 | ka6sox-office | the ones I have are for MPC86X |
| 02:42.08 | jacques | they have flash chip defs? |
| 02:44.04 | ka6sox-office | I think that the BDM knows how to manipulate the registers in the CPU to program the flash |
| 02:44.21 | ka6sox-office | we just download the file via ftp and then program it into the flash. |
| 02:45.07 | jacques | but there has to be a section in the cfg that defines certain properties of the flash is my understanding |
| 02:45.21 | ka6sox-office | yes. |
| 02:45.38 | ka6sox-office | lemme see if I can log into the bdi if nobody else is using it and dump the cfg. |
| 02:45.42 | NAiL | isn't the ds101g+ a mcp824x? |
| 02:45.51 | ka6sox-office | yes it is...(I have one here) |
| 02:46.19 | jacques | ka6sox-office, can't you just look at the tftp dir where the bdi gets its config file? |
| 02:46.29 | ka6sox-office | I think so. |
| 02:46.37 | jacques | cool |
| 02:46.41 | ka6sox-office | but I've never had to play with that. |
| 02:46.48 | jacques | ah |
| 02:46.53 | jacques | neither have I before today |
| 02:46.59 | ka6sox-office | since we have been using the same target for a while (like the last 3 years. |
| 02:47.01 | ka6sox-office | ) |
| 02:47.42 | jacques | heh |
| 02:50.48 | ka6sox-office | the box is in use but will be free in 30 minutes |
| 02:51.06 | ka6sox-office | Ron and Stephanie are at home debugging the board that they are working on. |
| 02:51.14 | ka6sox-office | (kernel drivers for SCSI) |
| 02:52.15 | jacques | cool |
| 03:17.53 | ka6sox-office | I"m using CVS for all my CMS needs...its old, its slow but it works :P |
| 03:28.04 | ka6sox-office | Can I be excused...my brain is full! |
| 03:30.57 | jacques | must... resist... starbucks |
| 03:31.44 | ka6sox-office | you *will* be up at 3am....still! |
| 03:40.58 | ka6sox-office | talk to me....I'm your Starbuck's Anonymous partner... |
| 03:44.49 | jacques | I'm still undecided |
| 03:45.10 | jacques | I'd rather be building latest debianslug |
| 03:49.50 | ka6sox-office | LE? |
| 03:50.40 | jacques | yes |
| 04:02.41 | ka6sox-office | ah |
| 04:34.26 | ka6sox-office | mornin mate. |
| 04:34.42 | z3ro | hi :) |
| 04:34.44 | z3ro | lennert: ping |
| 04:34.56 | ka6sox-office | north or south Island? |
| 04:35.15 | z3ro | ka6sox-office: south |
| 04:35.19 | z3ro | NAiL: hmm, okay. |
| 04:35.20 | ka6sox-office | 2hrs and he will have one eye open. |
| 04:35.27 | z3ro | NAiL: I don't know his timezone. :p |
| 04:35.32 | z3ro | ka6sox-office: okay. :) |
| 04:35.36 | ka6sox-office | GMT+1 |
| 04:35.40 | NAiL | z3ro: It's 05:35 where lennert is IIRC |
| 04:35.51 | z3ro | okay |
| 04:36.08 | ka6sox-office | the Joys of worldwide development |
| 04:36.16 | NAiL | hehe |
| 04:36.26 | ka6sox-office | NAiL, never sleeps. |
| 04:36.32 | NAiL | the joys of worldwide development is what is keeping me up all the time ;) |
| 04:36.40 | ka6sox-office | not our fault! |
| 04:36.57 | ka6sox-office | z3ro, I honeymooned on South Island |
| 04:37.27 | z3ro | ka6sox-office: heh :p |
| 04:37.49 | ka6sox-office | I love the place. |
| 04:38.06 | z3ro | that, and the internet here is terrible. |
| 04:38.32 | ka6sox-office | k |
| 04:39.06 | ka6sox-office | I was there many years ao and it was dialup at best. |
| 04:39.28 | ka6sox-office | on the Otago Penninsula where I was for a bit it was non-existant! |
| 04:39.41 | z3ro | there is adsl now, but still nothing comparable to the rest of the world. |
| 04:39.59 | ka6sox-office | when your not stuck in .nz where are you? |
| 04:40.31 | z3ro | well, I live here (for now, anyway) |
| 04:40.52 | z3ro | hopefully in a few years I can move to another country. :) |
| 04:41.23 | ka6sox-office | I know a guy who just moved down there. |
| 04:41.31 | ka6sox-office | to Dunedin |
| 04:41.55 | z3ro | hmm |
| 04:51.39 | NAiL | lennert: ping? The DoC now works. Could you help me a tad with NAND stuff? :) |
| 05:13.20 | ka6sox | wb |
| 05:14.19 | z3ro | :) |
| 05:14.57 | ka6sox-office | I actually didn't see one Fry's electronics store in NZ when I was there...but I did see a Dick Smith. |
| 05:15.40 | z3ro | dse is horrible, for any real electronics parts, I go to sicom (or international order) |
| 05:17.30 | z3ro | damn... I was just looking around for a fpga placement/routing algorithm on google. |
| 05:17.34 | z3ro | didn't find anything. :( |
| 05:18.21 | z3ro | I was hoping for something like pcb routing algorithms where ansi.org has a few. |
| 05:20.27 | ka6sox-office | that I've not seen |
| 05:21.51 | z3ro | http://www.eecg.toronto.edu/~vaughn/challenge/challenge.html is the closest I've seen... but afaik, they target a "fake" fpga. |
| 05:21.56 | z3ro | not a real chip. |
| 05:22.20 | z3ro | but I wounder how different their fake chip would be to real xilinx fpga's (spartan/virtex) |
| 05:22.39 | z3ro | I mean, they would have to base the rules for the fake chip from a real chip for the results to have any meaning. |
| 05:28.16 | jacques | ka6sox-office, any luck on the bdi config file? |
| 05:28.22 | ka6sox | the nice thing about FPGAs and CPLDs is that (within reason) you can move things around |
| 05:28.29 | jacques | it should really just be in a /tftp dir somewhere |
| 05:28.29 | ka6sox | they left their connectin up |
| 05:28.37 | ka6sox | and just got back from dinner |
| 05:28.41 | ka6sox | I'masking now. |
| 05:28.44 | jacques | you shouldn't have to touch the bdi |
| 05:29.34 | ka6sox | he is logged in |
| 05:29.52 | ka6sox | and I don't want to mess with what he is doing.:) |
| 05:30.27 | jacques | logged into what? |
| 05:30.31 | jacques | I'm confused |
| 05:30.34 | ka6sox-office | the BDI |
| 05:30.41 | jacques | that should not matter at al |
| 05:30.45 | ka6sox-office | k |
| 05:31.01 | jacques | the bdi downloads its config file via tfp on boot |
| 05:31.19 | jacques | somewhere there is a unix or windows box running a tftpd and the config file/s are there |
| 05:31.32 | ka6sox-office | let me poke around the ppc devel lappy. |
| 05:31.39 | ka6sox-office | thats where its going to be. |
| 05:31.43 | jacques | ok |
| 05:33.45 | jacques | bah, there is no mention whatsoever about the location of firmware upgrades for the bdi2000 on the abatron site |
| 05:34.12 | jacques | they don't even say you have to buy them - nothing other than that they exist and all the cool new features I don't have |
| 05:36.08 | ka6sox-office | got it. |
| 05:36.14 | ka6sox-office | found the files |
| 05:36.15 | jacques | :-D |
| 05:36.16 | ka6sox-office | the config ones. |
| 05:36.42 | ka6sox-office | I'll zip em up and send em where? |
| 05:36.46 | ka6sox-office | or put em where? |
| 05:36.48 | jacques | hmm |
| 05:36.59 | jacques | nudi ? that still exist? |
| 05:37.10 | ka6sox-office | heh...I"m looking right at it. |
| 05:37.21 | jacques | fastmail changed something an I can no longer connect with mutt, even following their instructions |
| 05:37.51 | jacques | yeah at least I can still login to nudi :-) |
| 05:38.38 | jacques | th omy ping times are hovering around 500ms |
| 05:38.48 | jacques | what's that about I wonder |
| 05:39.08 | jacques | final hop |
| 05:39.13 | jacques | link is saturated :-\ |
| 05:39.31 | ka6sox-office | ugh |
| 05:39.40 | ka6sox-office | okay its in my homedir on nudi |
| 05:39.42 | ka6sox-office | confs.tar |
| 05:41.14 | jacques | I see it :-) |
| 05:41.24 | ka6sox-office | ya but can you get it? |
| 05:42.06 | jacques | got it, thanks! |
| 05:42.15 | jacques | 5.7KB/s |
| 05:42.17 | jacques | :-D |
| 05:43.39 | jacques | oooh, this looks good |
| 05:43.46 | jacques | I really appreciate it ka6sox |
| 05:45.56 | ka6sox | np |
| 05:46.22 | ka6sox | this is for PPC850 and 860/862...not 8241 |
| 05:46.49 | jacques | yeah, I know, but the [FLASH] section/s look really informative |
| 05:47.58 | jacques | I spend 90% of today getting linux to run on a silly toshiba laptop, but tommorrow I need to teach the bdi2000 to write to the flash on our board |
| 05:48.01 | ka6sox | cool! |
| 05:48.02 | jacques | spenT |
| 05:54.32 | ka6sox-office | does this mean you resisted Starbuck's? |
| 05:56.37 | jacques | yep |
| 05:57.09 | ka6sox-office | so you are set? |
| 05:57.24 | ka6sox-office | wait until you see our new JTAG/LA setup. |
| 05:57.47 | ka6sox-office | up to 64 channels of 150mhz samples! |
| 05:58.52 | jacques | wow! |
| 05:59.13 | jacques | yep I am set for more bdi info than I can digest right now :-) |
| 05:59.27 | ka6sox-office | okya |
| 05:59.37 | ka6sox-office | this *is* the place for this kind of thing |
| 05:59.37 | jacques | and am building debianslug to play with lude for first time since sunday night |
| 05:59.45 | ka6sox-office | ah |
| 05:59.57 | ka6sox-office | I'm going to use BE. |
| 06:00.10 | ka6sox-office | (since there is a beautiful repo out there) |
| 06:00.43 | jacques | maybe I will convert to BE at some point, but I'm trying to limit the variables at this point |
| 06:02.08 | jacques | looks like pbrook's been doing a nice bit or work on qemu arm emulation over the last three weeks |
| 06:02.17 | jacques | (no BE yet that I can see tho) |
| 06:03.32 | ka6sox-office | k |
| 06:03.45 | jacques | "Fix Arm big-endian host bug." hmmm |
| 06:04.08 | jacques | it can run on a BE arm host but not emulate one? |
| 06:04.22 | jacques | getting closer I suppose |
| 06:05.05 | ka6sox-office | heh |
| 06:14.47 | dyoung-away | jacques: sorry link saturation is my fault |
| 06:14.58 | dyoung-away | was sucking 14G, but its taking a REALLY REALLY long time. |
| 06:15.24 | ka6sox-office | how much do you have left to suck? |
| 06:15.37 | dyoung-away | most of it. |
| 06:15.52 | dyoung-away | at this rate it would be faster to fedex the disk here me suck it, the fedex it back |
| 06:16.05 | dyoung-away | I only have 4.5G |
| 06:16.16 | jacques | 14GB??? |
| 06:16.41 | ka6sox-office | total downloaded? |
| 06:16.44 | ka6sox-office | or left? |
| 06:17.05 | dyoung-away | I have 4.5G |
| 06:20.04 | ka6sox-office | maybe I can find a 10gb hd to send you |
| 06:21.40 | dyoung-away | This is a bit ludicrous. |
| 06:21.50 | dyoung-away | jacques: are you still sucking? |
| 06:21.53 | dyoung-away | I can interrupt this. |
| 06:22.36 | jacques | dyoung-away, nope, I only needed a few kB |
| 06:22.44 | jacques | and I got them |
| 06:22.47 | ka6sox-office | I sent him a small tar file |
| 06:23.15 | dyoung-away | btw, I dont remember if I mentioned it; but it was pretty cool meetin up with y'all. |
| 06:24.32 | ka6sox-office | :) |
| 06:24.39 | jacques | yep, same here |
| 06:24.49 | jacques | we need to do it again |
| 06:25.10 | jacques | (even before next year's SCALE) |
| 06:25.22 | NAiL | yes |
| 06:25.26 | NAiL | Norway is a nice place ;) |
| 06:25.43 | jacques | heh |
| 06:26.26 | ka6sox-office | NAiL, you got any sun yet? |
| 06:26.58 | NAiL | sun? what is that? |
| 06:27.02 | NAiL | ;) |
| 06:29.11 | ka6sox-office | heh |
| 06:29.30 | ka6sox-office | you know....that warm ball in the sky periodically |
| 06:30.48 | NAiL | oh, the thing that makes it near impossible to sleep in summer... |
| 06:30.56 | NAiL | nah, haven't seen that much of it yet |
| 06:31.20 | dyoung-away | yeah, I wonder if we can try sneek into LWE.... |
| 06:31.37 | jacques | we did it before :-) |
| 06:32.04 | dyoung-away | Dunt Dunt Dunt Dunt. |
| 06:32.18 | dyoung-away | (I just snuck in to a convention today too) |
| 06:32.35 | dyoung-away | jacques: I should mail you a scan of this brochure. |
| 06:32.44 | dyoung-away | the guy is actually selling this. |
| 06:33.03 | NAiL | ka6sox-office: btw, someone mentioned you when I asked about stickers |
| 06:33.04 | dyoung-away | its a float with 1000m of semi-rigid hose around 8" ida |
| 06:33.08 | dyoung-away | dia. |
| 06:33.27 | dyoung-away | it has little thingos in it like heart valves. |
| 06:33.42 | dyoung-away | so you throw it over, and it "pumps" up water through the motion of the sea. |
| 06:33.58 | dyoung-away | so all this cold water that gets pumped up to surface is supposed to prevent hurricaines. |
| 06:34.44 | jacques | lol |
| 06:36.06 | ka6sox-office | is that the answer to global warming? |
| 06:36.12 | dyoung-away | So I have this bridge for sale too..... |
| 06:36.21 | ka6sox-office | its in Arizona |
| 06:36.37 | dyoung-away | Thats oaky, I'm still selling it. :-) |
| 06:38.02 | jacques | isn't london bridge in arizona? |
| 06:38.51 | ka6sox-office | yep...thats the one. |
| 06:38.52 | NAiL | Tower bridge, you mean? Yeah. And it's for sale :-P |
| 06:39.12 | ka6sox-office | NAiL, are you the exclusive agent? |
| 06:39.19 | NAiL | no, dyoung is |
| 06:39.47 | jacques | I'd rather buy land on the moon |
| 06:40.01 | NAiL | (which is equally worthless) |
| 06:40.22 | dyoung-away | Hey I can sell you a cozy crater on the moon too. |
| 06:41.07 | NAiL | WOOHOO :-D |
| 06:41.25 | dyoung-away | doesnt include air. |
| 06:41.27 | NAiL | "working" |
| 06:41.31 | jacques | it has an lcd?? |
| 06:41.35 | NAiL | no, mine has |
| 06:41.38 | NAiL | :) |
| 06:42.13 | NAiL | echo "test" > /dev/ttyUSB0 gives me "^@test<chinese char><chinese char>" |
| 06:42.34 | NAiL | I had just soldered TX to the wrong pin |
| 06:42.41 | jacques | lol |
| 06:43.27 | NAiL | ah |
| 06:43.36 | NAiL | echo -n doesn't give the chinese chars |
| 06:43.53 | NAiL | things start working today |
| 06:45.29 | jacques | speaking of working |
| 06:45.34 | jacques | I gotta go to sleep |
| 06:46.58 | jacques | see you guys tomorrow |
| 06:47.11 | dyoung-away | nighty. |
| 06:49.32 | ka6sox-office | nitey jacques |
| 07:16.57 | ka6sox | hybird? |
| 07:17.05 | NAiL | nah, diesel |
| 07:19.13 | NAiL | yay |
| 07:19.32 | NAiL | the display on my DS101 now reads "Welcome to OpenSyn!", with no chinese chars at all ;) |

| 09:09.48 | AchiestDragon | hi |
| 09:19.07 | ka6sox | 'lo |
| 09:19.14 | ka6sox | just about to crash |
| 09:19.25 | ka6sox | but it was a good day |
| 09:19.34 | AchiestDragon | k kool |
| 09:20.23 | AchiestDragon | im going to finalize the bus spec and try to finalize the spec for the ep board today |
| 09:21.27 | ka6sox | excellent. today I downloaded all the specs and when I get the printer spool working tommorrow I'll print them up so that I have my Project notebook setup. |
| 09:21.51 | dyoung-away | Okay, so do I not need to run a heat profile on a cardbus card then? |
| 09:22.05 | ka6sox | at this point no. |
| 09:22.18 | dyoung-away | Grr |
| 09:22.21 | ka6sox | I think that the EP9302 only takes 1 watt. |
| 09:23.20 | AchiestDragon | i have been running my ts7200 for some time now , the heat problem seems to be the net phy |
| 09:23.32 | AchiestDragon | that realy could do with a heatsink |
| 09:24.19 | AchiestDragon | the termal that would be good to have is that for the fpgas in stack |
| 09:25.23 | ka6sox | what is the phy? make/model? |
| 09:25.30 | AchiestDragon | given that we can stack pcbs at 1/8" apart or multiples of that |
| 09:26.38 | AchiestDragon | micrel ks8721(8 or |
| 09:26.51 | AchiestDragon | B) L |
| 09:27.30 | ka6sox | I have little bits of heatsink that if I knew the package size I could cut one off. |
| 09:27.44 | ka6sox | you would need some thermal epoxy. |
| 09:27.57 | AchiestDragon | when its been runing for about a day on a t10 then it is hot but still tuchable |
| 09:28.33 | ka6sox | k |
| 09:28.54 | AchiestDragon | thats in free air not in an enclosure |
| 09:29.54 | z3ro | hehe :p |
| 09:30.05 | z3ro | I should probably try to figure out the rest of the file format first... |
| 09:30.16 | AchiestDragon | i have setup a small fan that blows air accross it , without a heatsink and it cools it well , butwould think a heatsink would work better , less noise |
| 09:30.27 | ka6sox | yes |
| 09:30.37 | ka6sox | okay I'm doing the keyboard dived. |
| 09:30.40 | ka6sox | er dive |
| 09:31.44 | z3ro | the first part of the xilinx-xdm v1.4e files is easy, but the later part I haven't figured out yet. :( |
| 09:32.25 | z3ro | anyone want to take a look at http://z3ro.geek.nz/fpga.html#Xilinx-_0027XILINX_002dXDB_0027-Parsing (look at 'XILINX-XDM V1.4e' subsection, example 1) |
| 09:32.34 | z3ro | maybe a fresh set of eyes will help. |
| 09:46.45 | lennert | AchiestDragon: you can turn off the micrel phy on the TS board, gpio port H bit 2 |
| 09:46.56 | lennert | z3ro: pong |
| 09:46.57 | lennert | NAiL: pong |
| 09:47.20 | z3ro | lennert: hi |
| 09:47.49 | NAiL | http://pastebin.com/568254 <-- Do you know why I only get two partitions? :) |
| 09:48.05 | z3ro | lennert: just wanted to continue our discussion about fpga stuff (and maybe get some help with the xdm v1.4e format) |
| 09:48.10 | AchiestDragon | lennert: maybe, but no help turning it off if your communicating to to it over telnet on the ethernet |
| 09:50.14 | lennert | AchiestDragon: true :) |
| 09:50.26 | lennert | AchiestDragon: didn't know whether you needed it |
| 09:50.48 | lennert | NAiL: how big is the diskonchip, 16 meg? |
| 09:50.56 | NAiL | yup |
| 09:51.10 | lennert | NAiL: redboot? |
| 09:51.12 | lennert | z3ro: a second.. |
| 09:51.20 | z3ro | lennert: okay |
| 09:51.33 | NAiL | lennert: yes? |
| 09:51.45 | lennert | NAiL: do you have redboot partition table scanning compiled in? |
| 09:52.08 | NAiL | no, since I *believe* that the RB partition table is empty on the DS101. I can try though |
| 09:52.15 | lennert | ah, right |
| 09:52.19 | lennert | so what does 'fis list' give in redboot? |
| 09:52.31 | NAiL | nothing, since redboot can't read the DoC |
| 09:52.40 | lennert | that's weird |
| 09:52.50 | NAiL | (it has a tacked-on thingy that reads the first two partitions to ram and does "exec") |
| 09:52.59 | NAiL | RedBoot doesn't have DoC support |
| 09:53.08 | lennert | so how many partitions _should_ there be? |
| 09:53.16 | NAiL | 6 or 7 |
| 09:53.27 | lennert | okay |
| 09:53.35 | lennert | how does the 2.4 kernel detect the partition table? |
| 09:53.44 | lennert | you might just have to hardcode the partition table into the linux sources |
| 09:53.49 | lennert | couple of other boards do that as well |
| 09:53.58 | NAiL | yeah, I've seen it |
| 09:59.46 | dyoung-away | har har like the stock 2.4 linksys nslu2 kernel hackery. |
| 10:00.00 | lennert | dyoung-away: hehe |
| 10:00.18 | lennert | same with the ts72xx for some reason, even though they do seem to have a redboot partition table |
| 10:00.27 | NAiL | http://www.nslu2-linux.org/gallery/album01/img_1983 <-- l33t DS101 :-D |
| 10:00.43 | dyoung-away | D00d |
| 10:00.47 | dyoung-away | you kutt it. |
| 10:00.53 | NAiL | yeah |
| 10:01.08 | NAiL | doesn't look good on the pic though |
| 10:01.21 | NAiL | looks ok when you don't throw a flash at it ;) |
| 10:01.22 | AchiestDragon | was reading the redboot on the ep9302 yesterday |
| 10:01.58 | AchiestDragon | it looks in a few diferent locations to load a 2k loader that loads the rest |
| 10:02.43 | AchiestDragon | serial , and a few diferent ram locations & eeprom |
| 10:02.55 | lennert | AchiestDragon: yeah |
| 10:03.18 | lennert | AchiestDragon: they have TS-NANDBOOT, a small loader, which then loads TS-BOOTROM, and that loads redboot |
| 10:03.35 | lennert | AchiestDragon: i'm not sure how they boot TS-NANDBOOT, but i think the cpld emulates a spi rom or something |
| 10:03.40 | lennert | AchiestDragon: as the ep93xx can boot from spi rom |
| 10:04.23 | AchiestDragon | they should be able to boot direct from the flash |
| 10:04.51 | NAiL | lennert: The strange thing is that *some* ds101's can do "fis list" |
| 10:05.00 | NAiL | Name FLASH addr Mem addr Length Entry point |
| 10:05.00 | NAiL | RedBoot 0x50000000 0x50000000 0x00060000 0x00000000 |
| 10:05.00 | NAiL | zImage 0x50060000 0x11600000 0x00180000 0x11600000 |
| 10:05.02 | NAiL | rd.gz 0x501E0000 0x10800000 0x006E0000 0x10800000 |
| 10:07.53 | lennert | hmmm |
| 10:07.59 | lennert | they have a hardcoded partition table then |
| 10:08.20 | lennert | AchiestDragon: yeah, but only the ts7200 has NOR flash, the rest has NAND |
| 10:08.44 | lennert | AchiestDragon: so, i think the cpld emulates a spi rom from the first N kb of NAND |
| 10:09.24 | AchiestDragon | does that flash chip have a boot block thats nor compatable |
| 10:09.44 | lennert | uhm, no? |
| 10:09.51 | AchiestDragon | k |
| 10:09.54 | lennert | it's just 8 bits of data bus, no address pins, ALE/CLE/WE/nCS pins |
| 10:23.59 | AchiestDragon | its a 16 bit flash in the ts72xx |
| 10:30.38 | AchiestDragon | no the cpld does not have a connection to the spi lines , there brought out to the dio header and used as gpio not spi |
| 11:01.45 | AchiestDragon | ok so intel dont have the data for the te28f128 thats easy to find on there site |
| 11:02.16 | dyoung-away | I have that data sheet. Hang on |
| 11:05.22 | dyoung-away | Ok the intel document number is 29066721 |
| 11:05.27 | dyoung-away | I can mail it to you too.... |
| 11:05.28 | AchiestDragon | but from the ep9301 data it can boot from ether serial , eeprom , async flash or sram/rom , sync flash or sdram or spi |
| 11:06.07 | AchiestDragon | no point , theres better devices arround |
| 11:07.41 | AchiestDragon | like why have a 32mb device when we could have a 512mb |
| 11:09.28 | AchiestDragon | debian arm fits in a 256mb c/f , could have it loaded onto the onboard flash |
| 11:09.43 | dyoung-away | really? |
| 11:09.55 | dyoung-away | I guess for the basic package set. |
| 11:11.51 | AchiestDragon | they do 1G devices also , so with 2 chips thats a 2G block although looks like there may be an address limit of 256mb per device on the ep9302 |
| 11:13.13 | AchiestDragon | 64mb if async mode is used |
| 11:16.42 | lennert | AchiestDragon: my ts7250 has an 8bit NAND flash part |
| 11:17.14 | lennert | AchiestDragon: okay, i don't know how else they do that then, they must be using either the CSx, the spi rom or the serial method for booting |
| 11:17.23 | lennert | AchiestDragon: and the first block of NAND flash does have the CRUS header in it |
| 11:17.58 | AchiestDragon | then there booting it direct |
| 11:18.16 | AchiestDragon | its just read as a memory location and booted |
| 11:18.18 | lennert | but the cpld doesn't connect to all the address lines, iirc |
| 11:19.48 | AchiestDragon | but the ep9301/2 devides the memory up into 16 blocks that some are provided as ce outputs for a unique address space |
| 11:20.42 | AchiestDragon | so all the 64mb address space is avalable to each device |
| 11:21.36 | lennert | the cpld only connects to A25, A24, A23, A22 |
| 11:21.39 | AchiestDragon | the sdram is mux'ed ant theres provision for 4 sync devices so 256mb per sync device is posible |
| 11:21.44 | lennert | and you can't boot directly off the nand flash |
| 11:21.53 | lennert | so there must be some other way they're doing it |
| 11:23.05 | lennert | z3ro: ok, let me find those files |
| 11:23.30 | z3ro | lennert: do you want me to upload example files? |
| 11:23.43 | lennert | z3ro: example files for what? |
| 11:24.05 | z3ro | a ngc file, and the decrypted version. |
| 11:24.24 | lennert | i'm not sure if i want to go there :) |
| 11:24.32 | z3ro | or were you talking about different files? |
| 11:24.51 | lennert | the files that describe the .bit bits i found so far |
| 11:24.58 | z3ro | oh, okay |
| 11:25.05 | lennert | i should have them somewhere here.. *looks* |
| 11:27.12 | lennert | i used the tools at http://svn.wantstofly.org/vhdl/utils/ for diffing .bit files |
| 11:27.31 | lennert | there's a file that'll decode the bitstream and a simple shell script that can diff two decoded dumps |
| 11:27.58 | z3ro | okay :) |
| 11:28.05 | lennert | can't find the other files yet |
| 11:28.14 | z3ro | let me know when you do. |
| 11:29.49 | AchiestDragon | ok before i get any further with the ep board theres a few points that i could do with some feedback on |
| 11:31.00 | AchiestDragon | the spec so far is 4 sdram devices ( 64mb seems to be the biggest type i can get ) so 256mb ram |
| 11:33.07 | AchiestDragon | although should support 256mb devices and 4 would give 1Gb , need to study the ep9302 data a bit more to see the size limit of them |
| 11:33.18 | lennert | z3ro: i put some stuff in http://www.wantstofly.org/~buytenh/xilinx/ |
| 11:33.30 | lennert | z3ro: i think there was more but no idea where i put it.. |
| 11:33.39 | z3ro | lennert: okay |
| 11:33.58 | lennert | z3ro: for the xc3s50 it has which frames contain the keeper/driveattrbox/ioattrbox/slew bits |
| 11:34.11 | lennert | z3ro: pull up/pull down/io standard/drive strength |
| 11:34.20 | z3ro | lennert: 403 on http://www.wantstofly.org/~buytenh/xilinx/ |
| 11:34.25 | lennert | z3ro: the bram as well |
| 11:34.31 | lennert | oh, a sec |
| 11:34.38 | lennert | fixed |
| 11:34.38 | AchiestDragon | 2 flash chips at 64mb each , would like to suport 512mb total but that may not be posible |
| 11:34.52 | z3ro | lennert: okay, thanks. |
| 11:34.53 | lennert | all the iob bits are in there |
| 11:35.14 | lennert | i'm sure i had the clb bits decoded too |
| 11:35.28 | lennert | and bits of the routing |
| 11:35.43 | lennert | the easiest way to go about it is via xdl files |
| 11:35.52 | lennert | write an xdl file, convert it to ncd, and bitgen it |
| 11:36.00 | lennert | change the xdl slightly, same thing again, and bit-diff it |
| 11:36.16 | z3ro | hmm, I see. |
| 11:36.50 | lennert | i haven't had time to work on this lately at all |
| 11:37.03 | z3ro | okay, well, this information should be helpful. :) |
| 11:37.17 | AchiestDragon | the expantion bus is a 50mhz bus , and suport is provided for etherent , 1 rs232 , 2 usb , and a 16 bit dio port , theres a full 14 pin arm jtag for the ep9302 and the other ports are brought to a connector so if the user wants he can get to them |
| 11:37.25 | lennert | good luck |
| 11:37.32 | z3ro | btw, do I have permission to reference this work or include information from the files, and do you want credit or to remain anonymous? |
| 11:38.16 | AchiestDragon | any requests for extras or thougts on the spec |
| 11:38.38 | lennert | z3ro: feel free to incorporate everything, but please keep me anonymous |
| 11:38.55 | z3ro | lennert: okay, absolutly. |
| 11:38.56 | lennert | z3ro: the files are under the do whatever you want with them license |
| 11:39.05 | z3ro | okay |
| 11:39.13 | lennert | AchiestDragon: sounds good, not sure what else to add |
| 11:40.54 | AchiestDragon | the fpga board for is next , and an expation board that will give CF, ide and video, audio and ps2 is planned later |
| 11:41.25 | AchiestDragon | fpga board for the jtag /anlizer |
| 11:43.59 | AchiestDragon | is wondering atm if i can use a cpld to frig the ep9302 into using the sdram timings to let us use ddr rams then may be able to get more ram using less chips |
| 11:59.03 | AchiestDragon | :S looks like the ram is limited to 4 64mbyte blocks so 256mb ram is going to be the max |
| 11:59.46 | AchiestDragon | and 128mbytes of flash with the 2 chips |
| 11:59.52 | AchiestDragon | that enough ? |
| 12:01.19 | AchiestDragon | theres also 128mb of ddr ram on each fpga card and alowance for 64mb of video ram |
| 12:02.59 | AchiestDragon | btw we have 2 external dma chans on this that the ts72xx did not impliminet |
| 12:20.23 | z3ro | lennert: are you interested in the xilinx-xdb v1.4e format, used in the ngo and ngd files? I put some example files and diff's online, but I'm having a hard time deciphering the format of the decrypted content. thought maybe you might want to look at it. |
| 12:20.46 | z3ro | the string table is easy to figure out, but the rest is less obvious. |
| 12:22.36 | lennert | z3ro: no, please -- i'd like to stay out of that |
| 12:23.37 | z3ro | lennert: hmm. I thought you would want to crack these formats, since you're already working on the 'configuration bits' problem... :( |
| 12:23.50 | z3ro | lennert: is it some legality thing? |
| 12:24.08 | lennert | yeah |
| 12:24.20 | z3ro | hmm :( |
| 12:24.34 | lennert | i believe that i'm in the clear as long as i just try to find out what bits do what in the .bit file, but i'm not so sure about de_crypt_ing their file formats |
| 12:24.51 | lennert | decrypting = circumventing protection measure, yadda yadda |
| 12:25.26 | z3ro | afaik, it's legal to reverse engineer a file format in order to find out what information it contains. |
| 12:25.55 | z3ro | I think it's only illegal if it's patented. |
| 12:26.11 | z3ro | but I'm not a lawyer, I've just read this online somewhere. |
| 12:27.52 | AchiestDragon | guess if you read the data from the chip and store it in your own format then theres not much they can do about it |
| 12:28.17 | AchiestDragon | unless the data beeing read is theres |
| 12:29.17 | z3ro | well, I'm just stuck on figuring out one of their file formats. The file is "encrypted", but it's just xor encryption, so it's not like they wanted it to be secure... |
| 12:29.25 | z3ro | the decoded content is what I'm stuck on. |
| 12:29.39 | z3ro | first part is a string table, but the rest is very strange. |
| 12:29.52 | z3ro | it's all ascii (the decoded content) |
| 12:30.25 | lennert | i would concentrate on the xdl file format |
| 12:30.35 | lennert | xdl is all ascii representation of an ncd file |
| 12:30.41 | lennert | xilinx provide tools to convert to/from ascii |
| 12:30.45 | lennert | and ascii is human-readable |
| 12:30.48 | *** join/#openjtag prpplague (n=billybob@72.22.131.136) |
| 12:30.50 | lennert | so you're in the clear there |
| 12:31.00 | z3ro | I'd like to avoid their tools... |
| 12:31.27 | lennert | i think you'll have to use their tools at least initially |
| 12:31.39 | lennert | unless you can have someone else do the 'cleanroom' work |
| 12:31.46 | z3ro | take a look at z3ro.geek.nz/fpga/xdm/0_foobar.ngo.indent (an indented version of the decrypted content) |
| 12:32.21 | z3ro | that's the data inside a .ngo file. |
| 12:32.51 | z3ro | it's the text after the first 4 lines that I'm stuck on |

| 14:02.19 | lennert | prpplague: come to fosdem |
| 14:02.54 | prpplague | wish i could, busy on too many projects and short on $$ this month |
| 14:03.08 | lennert | too bad.. |
| 14:03.15 | prpplague | yea |
| 14:03.26 | prpplague | lennert: i used to have a large budget for conferences |
| 14:03.31 | prpplague | lennert: at my last company |
| 14:03.50 | prpplague | lennert: then they go some new management and they deemed it a waste of money |
| 14:04.04 | prpplague | lennert: no training, no conferences, no certs |
| 14:04.18 | prpplague | lennert: they had 20+ people quit on the same day |
| 14:04.21 | lennert | haha |
| 14:04.26 | lennert | out of how many? |
| 14:04.34 | prpplague | 300 |
| 14:04.54 | lennert | probably the smartest 20 as well |
| 14:04.56 | prpplague | over the next month they lost a total of about 75 more ppl |
| 14:05.14 | prpplague | including myself, hehe |
| 14:05.49 | lennert | i'm sure the management proudly advertised their 33% staff reduction |
| 14:06.04 | lennert | to show their cost-cutting methods were effective |
| 14:06.06 | prpplague | lennert: yea thats how they played it up |
| 14:06.24 | lennert | to CEO: "Oh, you didn't want us to cut productivity by 100%? You didn't tell us.." |
| 14:06.38 | prpplague | lennert: i found out later that the vp that made the decision about the conferences got a giant bonus for reducing costs |
| 14:06.58 | lennert | company went down the crapper yet? |
| 14:07.04 | prpplague | lennert: yea they are still in business, but the moral is horrible |
| 14:07.13 | lennert | serves them right |
| 14:07.17 | prpplague | lennert: most of the ppl working there are "rejects" |
| 14:07.27 | lennert | that sucks for them |
| 14:07.41 | lennert | the central IT institution of Leiden University is similar |
| 14:07.51 | lennert | management was replaced by idiots one day |
| 14:08.00 | lennert | all the people that had no trouble finding something different quit |
| 14:08.07 | prpplague | hehe |
| 14:08.10 | lennert | so now they only have people that are stuck there because they are incompetent |
| 14:08.29 | lennert | so whatever you want to do here, you have to deal with incompetent idiots |
| 14:08.30 | prpplague | lennert: yea the management was replace all with sales people |
| 14:08.39 | prpplague | jeeze |
| 14:09.13 | lennert | (OT, www.stfu.se/stfuse.swf is fun :) |
| 14:09.15 | prpplague | lennert: the company i work for now has never really had a budget for conferences |
| 14:09.32 | prpplague | lennert: i'm trying to get them to see the benefit of them |

| 14:26.31 | lennert | okay :) |
| 14:28.11 | prpplague | lennert: maybe a Duvel or Chimay |
| 14:28.25 | lennert | mmm duvel |
| 14:29.28 | prpplague | lennert: i got this nice set of 4 tulip duvel glasses with a large 1500ml bottle once |
| 14:29.49 | prpplague | lennert: my #$%#%^$#%^ ex-wife put them in the dishwasher and they all got broken |
| 14:30.25 | lennert | whoops |
| 14:30.42 | lennert | i can see why you divorced her ;) |
| 14:30.45 | prpplague | hehe |
| 14:30.47 | lennert | inexcusable |
| 14:31.06 | prpplague | lennert: hehe no i divorced her because she was a bitch, hehe |
