| 00:00.11 | T0mW | memvars |
| 00:00.39 | jacques | it was challenging - when we started the toolchains hadn't even been tested in BE (mostly) |
| 00:00.48 | jacques | and definitely not armeb softfloat |
| 00:01.14 | T0mW | IIRC, there were type-coercion issues with big endian which little endian avoids |
| 00:01.16 | jacques | there were problems with glibc too |
| 00:01.43 | jacques | now we are in the process of getting a new arch (armeb) added to debian (officially) |
| 00:02.14 | T0mW | uint foo; uchar bar; if (foo != (uint)bar) .... |
| 00:02.44 | T0mW | something like that anway |
| 00:02.51 | T0mW | s/anway/anyway/ |
| 00:03.06 | T0mW | jacques: but, you have to deal with it, right, heh |
| 00:03.37 | T0mW | jacques: so, what are you doing that is usefull with your unit? |
| 00:04.49 | jacques | useful? I don't do useful :-) |
| 00:05.23 | jacques | but seriously, I was using mine to compile things that don't cross-compile properly - like perl and emacs |
| 00:06.11 | jacques | since I've been moving around last few months I haven't done much with the units themselves tho I have been playing a lot with emulators lately |
| 00:06.52 | T0mW | oh, where are you earning your rent money lately? |
| 00:07.27 | jacques | I haven't earned money in quite a while - was living on savings in oregon and now am in the process of moving around and trying to find a job |
| 00:09.06 | jacques | BIAB |
| 00:11.05 | T0mW | sigh |
| 00:11.22 | T0mW | ld still insists on linking with the wrong libraries |
| 00:20.13 | thraxisp | jacques: what toolchain are you using? |
| 00:20.45 | T0mW | my own |
| 00:20.48 | T0mW | gcc |
| 00:21.31 | T0mW | looks like when I build gcc, the multilib option means both thumb + thumb_iw, but not plain arm32 library for libgcc |
| 00:21.48 | T0mW | newlib is building all three |

| 00:33.04 | jacques | thraxisp, crosstool and oe generated |
| 00:34.39 | jacques | since we have multiple dists (one is backwards compatible with linksys binaries) we use a gcc 3.3/ glibc 2.2.5 and a gcc 3.4 / glibc 2.3.x |
| 00:34.58 | jacques | we also have uclibc based dists |
| 00:39.32 | thraxisp | thanks. I'm trying to update tools for a similar platform. |
| 00:41.55 | thraxisp | I was trying to build them with buildroot. The toolchain we have is missing some libraries. |
| 00:42.22 | jacques | for uclibc based, buildroot should be good |
| 00:43.03 | thraxisp | I've been working on one for a few weeks. The big-endian and no FPU seems to be a problem for buildroot. |
| 00:44.09 | jacques | hmm, I had built armeb uclibc softfloat toolchains with it in late 2004 |
| 00:44.18 | jacques | well like sept 2004 |
| 00:44.53 | jacques | well I'm 99% sure they were softfloat |
| 00:46.03 | thraxisp | recent versions of buildroot seem to be problematic. |
| 00:46.18 | jacques | ah I wonder what changed |
| 00:47.59 | thraxisp | Oct 15 fails and I left Oct 1 building at work. |
| 00:49.18 | jacques | what type of errors are you seeing? |
| 00:51.45 | thraxisp | a few specific errors. The most recent ones are mixed host and target libraries when building libstdc++. |
| 00:52.04 | thraxisp | There is also a problem building a shared uclibc. |
| 00:52.11 | jacques | ugh, I've seen stuf flike that - it required patches I think |
| 00:52.17 | thraxisp | both were reported in the tracker. |
| 00:54.28 | thraxisp | I have a patch for the latter but it doesn't make sense. There are functions missing from libgcc when uclibc is compiled. |

| 18:50.41 | jamie | Is anyone using uclinux-2.4.26 (or thereabouts) with a hard disk and ext3? |
| 18:51.36 | jamie | I'm seeing data loss and other problems, and wonder if it's just my system or a known uclinux issue. |
| 18:53.10 | prpplague | jamie: harddisk specific or ata interface such as a cf card to ide adapter? |
| 18:53.43 | jamie | Ordinary hard disk - 40G Travelstar. |
| 18:53.59 | jamie | This is on a proprietary ARM board. |
| 18:54.38 | prpplague | jamie: sorry no, all i have is cf used as hd's |
| 18:54.45 | jamie | With potentially dodgy IDE drivers or even dodgier electronics. However, it might be uclinux memory management or scheduling. |
| 18:54.55 | jamie | Have you used ext3 on them? |
| 18:55.09 | jamie | I'm wondering if ext3's journalling is not working properly with uclinux 2.4.x. |
| 18:55.25 | jamie | (cf should be no different than hd for this). |
| 18:55.52 | prpplague | jamie: i've used it in the past however i was worried about buring up the cf flash so i switched to ext2 |
| 18:56.12 | prpplague | jamie: i didn't seem to have any problems that i noticed |
| 18:56.16 | jamie | I'm more worried about booting to a corrupt disk image, considering I write logs to it quite often. |
| 18:56.28 | jamie | IT seems to be fine while it's running. |
| 18:57.08 | jamie | But if I change a file / create a file / whatever, then do "sync" which should commit it, then power cycle, often the changes are absent. |
| 18:57.17 | jamie | And sometimes I get I/O errors which indicate fs corruption. |
| 18:57.28 | jamie | Both of those should never happen, in principle, with ext3. |
| 18:57.58 | jamie | I also find that if I write to the disk _too fast_, the system crashes. I suspect the queuing of I/O requests or dirty data is a bit buggered in uclinux 2.4.x. |
| 18:58.22 | cdm | I think the ipod linux boys would have seen that if it was the case. |
| 18:58.23 | prpplague | hmmm |
| 18:58.25 | jamie | (Because I suspect that the system is filling with dirty data, then panics as it can't allocate any more). |
| 18:58.27 | cdm | sounds like a bad ATA driver. |
| 18:58.49 | jamie | It could be. One out of 13 boards corrupts data regularly, though I haven't seen it with the others. |
| 18:58.50 | prpplague | i'm with cdm |
| 18:59.05 | jamie | And it is a proprietary driver whose code does not inspire confidence. |
| 18:59.11 | prpplague | jamie: noisy trace? |
| 18:59.31 | prpplague | jamie: maybe the pcb has a minor trace problem |
| 18:59.31 | cdm | If the driver was chewing up memory the OMM killer would still run before the system died. |
| 18:59.42 | jamie | prpplague: Seems likely there are quite a few, given the various I2C / IDE / random lockup problems on various instances of this board :) |
| 19:00.27 | jamie | I'm just trying to pin down the problem, and checking if it's a known problem. |
| 19:01.00 | jamie | cdm: I was wondering if it was a generic I/O buffer management thing, given that uclinux changes that area of linux quite significantly. I'm not sure how mature the 2.4.26 patches were. |
| 19:01.10 | jamie | Alas, using 2.6 would be nice but not an option. |
| 19:01.26 | prpplague | jamie: i feel for ya, i spent the first week of this month tracing down an sdram init issue that turned out to be a badly implemented buffer |
| 19:01.49 | prpplague | jamie: can you scale down the main clock? |
| 19:02.09 | prpplague | jamie: i.e. if you are running at 200mhz might try running the system at 100mhz |
| 19:02.16 | prpplague | jamie: see if you have the same issue |
| 19:02.38 | jamie | prpplague: rumours are that it's possible. If I just wade through the vast directory of unfinished, dodgy, apparently abandoned proprietary code :/ |
| 19:02.40 | prpplague | jamie: most of the RF trace issues will not show up until after about 100mhz |
| 19:02.50 | cdm | jamie: the biggest users of uclinux that I know of are the ipod linux guys. And they have been running a 2.4 uclinux kernel driving ATA disks for sometime now. |
| 19:02.50 | prpplague | jamie: hehe |
| 19:02.53 | jamie | This thing ticks quite a bit higher than that. |
| 19:02.58 | jamie | It's a Sigma Designs video processor. |
| 19:03.04 | prpplague | ugh |
| 19:03.05 | prpplague | ugh |
| 19:03.06 | prpplague | ugh |
| 19:03.18 | jamie | I, of course, have faith in the h/w team to ensure noiseless operation :) |
| 19:03.39 | joe_bleau | jamie: where is sigma located? I think I may have known someone that worked there |
| 19:03.43 | jamie | And then I noticed a blatant ripple on the VGA output which rather dented my confidence in the h/w team ;-) |
| 19:03.44 | prpplague | jamie: hehe, i blame the hardware first |
| 19:03.54 | jamie | This board isn't from Sigma. |
| 19:04.06 | jamie | Just the main chip, and most of the code I have. |
| 19:04.28 | prpplague | jamie: ahh, well sigma for me is associated with their many resellers who are non-GPL compliant |
| 19:04.59 | jamie | joe_bleau: Somewhere in the USA. I don't know, they didn't respond to a direct attempt to buy stuff - we ended up getting our bits through a Taiwanese company that's bigger than Sigma :) |
| 19:05.05 | joe_bleau | The sigma I'm thinking of is in PA. They do broadcast video hardware. |
| 19:05.33 | jamie | joe_bleau: Probably the same. sigmadesigns.com. Used to be (or have something to do with) RealMagic, who designed the kit. |
| 19:06.05 | jamie | prpplague: I remember at one time, they were threatened with a suit by the Xine folks for nabbing code. |
| 19:06.23 | joe_bleau | Nope, this isn't the sigma my friend worked for. |
| 19:06.24 | prpplague | jamie: you might check with cosmicpenguin over in #elinux, iirc before he left CenturySoftware, he did some sigma work |
| 19:06.31 | jamie | But I gather they replaced the offending code. I haven't seen any blatant GPL-violations in the code that I've got yet - the kernel drivers come with source and it's LGPL'd. |
| 19:06.55 | jamie | Though I can easily see downstream vendors not complying - but that's not their problem. |
| 19:07.06 | prpplague | jamie: their resellers are still listed on the busybox hall of shame, and are frequented on the gplviolations.org mailing list |
| 19:07.39 | jamie | prpplague: Fair point. I think the company I'm getting stuff from don't really comprehend the GPL, but at least they supplied me with code anyway. |
| 19:07.51 | prpplague | jamie: anyway, cosmipenquin might be able to help ya out some |
| 19:07.53 | jamie | I never did sign the NDA, as it didn't make sense considering the licensing of the code. |
| 19:07.55 | jamie | Cheers. |
| 19:08.46 | prpplague | jamie: i'd still look at droping the clock freq below 100mhz if you can |
| 19:08.52 | jamie | So, new variation on question: how do I check what's being sent to the IDE driver? |
| 19:09.11 | jamie | I.e. how to I tell the difference between I/O requests not being sent to the driver, and the driver not sending them to the disk? |
| 19:09.42 | jamie | prpplague: That would be good anyway. Though I fear video decoding won't look too impressive. |
| 19:10.58 | prpplague | jamie: well, you will laugh, but when i have a problem like that, i usually load the code down with printk's and log like crazy to a uart |
| 19:11.33 | jamie | No laughing, I was thinking of it. Don't much like the idea, as "make" in the painfully convoluted source tree takes an hour. |
| 19:12.08 | prpplague | jamie: yea |
| 19:12.11 | jamie | And the UART would severally affect the timing, which might hide the problem. Then again, at least I'll know if it hides the problem :) Good plan. |
