| cwillu | rcn-ee, null pointer patch -> http://marc.info/?l=linux-netdev&m=127490516731906&w=2 | 00:00 |
|---|---|---|
| cwillu | going to try to run with that, and check if the memory leak was fixed elsewhere in 2.6.35 | 00:00 |
| cwillu | rcn-ee, okay, that patch fixes the null pointer at least, just got it booting | 02:38 |
| cwillu | currently 36 objects in slab size-2048 | 02:39 |
| cwillu | ... and no increases yet | 02:39 |
| cwillu | I'll ping back in an hour | 02:39 |
| cwillu | rcn-ee, note that this is _with_ the micrel patches, plus an additional one which I'll email you | 02:41 |
| cwillu | (er, it's actually the one from the link, so I'll only email you if you want a known-to-be-working copy of it :p) | 02:42 |
| rcn-ee | cool cwillu, was playing with the patch.. http://marc.info/?l=linux-netdev&m=127490516731906&w=2 needed for 2.6.34 and 2.6.35 ? ;) | 02:57 |
| cwillu | rcn-ee, haven't tested it under 2.6.34 | 02:58 |
| cwillu | rcn-ee, I'm suspicious that the null-pointer was a resulting from freeing the memory (i.e., what wasn't happening in .34 and earlier) | 02:59 |
| cwillu | you're referring to the 2 -> 4 line? | 02:59 |
| rcn-ee | okay, will queue up for 2.6.35 and get a build out, will test 2.6.34 tomorrow too just for kicks.. | 02:59 |
| cwillu | k | 02:59 |
| cwillu | re, leak test, it's still holding at 36 objects | 03:00 |
| cwillu | I've seen it go up to 100 or so, but it came back down | 03:00 |
| cwillu | so, it seems to be working properly | 03:00 |
| rcn-ee | yeah, it's more stablized then the previous version which shot up too fast.. | 03:00 |
| cwillu | going for a walk for an hour | 03:04 |
| cwillu | I might dance a little while I'm walking :p | 03:04 |
| cwillu | (road trip to replace / upgrade a bunch of hardware with bb + zippy's, and that wasn't going to work out to well if the max uptime of a zippy is a day :p) | 03:05 |
| rcn-ee | you should... too much stress from the ks8851 driver for you this weekend.. | 03:05 |
| cwillu | now I can actually write features to pack in before I leave wednesday :) :D \o/ | 03:05 |
| rcn-ee | yeah that would have sucked big time, nothing like hardware that refuses to stay up.. | 03:05 |
| cwillu | yep | 03:07 |
| cwillu | I knew I had this problem, but I thought I remembered that 2.6.33 didn't have it | 03:07 |
| cwillu | as it turns out, I just never used the ethernet under 2.6.33 :) | 03:07 |
| cwillu | I mean, I had a couple crappy workarounds, but I didn't want to have to explain their need to my boss :p | 03:08 |
| cwillu | hardware that stays up is better | 03:08 |
| rcn-ee | yeap... :) (crap replaced device 1 with 2, migrate to 2, shutdown 1, device 1 no longer repsonding..) | 03:09 |
| rcn-ee | (device 2 no longer responding) | 03:09 |
| cwillu | we get enough lightning strikes that I already have enough issues :p | 03:09 |
| cwillu | had a customer call me up saying my system was rebooting every few seconds | 03:10 |
| cwillu | he didn't feel the need to mention that his desktop was also doing the same | 03:10 |
| rcn-ee | yeah, you need good ups in the summer.. (or two or three in line..) | 03:10 |
| cwillu | in this case, if the power is out, they're not doing anything anyway | 03:13 |
| cwillu | and I've gone through the sd testing routine and so forth | 03:13 |
| cwillu | I'm actually considering reimplementing reboot as "sync; dontechodangerous b > /proc/sys-rq-trigger" | 03:13 |
| cwillu | nice and quick :) | 03:13 |

| furibondox | hi to everybody... | 13:26 |
| furibondox | I've the same problem... segmentation fault on line 282 in rootstock | 13:26 |
| furibondox | now I'm using a physical ubuntu Lucid installation | 13:27 |
| furibondox | any idea? | 13:27 |
| furibondox | http://www.mail-archive.com/ubuntu-bugs@lists.ubuntu.com/msg2382346.html | 13:30 |
| rsalveti | furibondox: known issue | 13:30 |
| rsalveti | furibondox: what rootstock version are you using? | 13:31 |
| rsalveti | bug 604872 | 13:31 |
| ubot2 | Launchpad bug 604872 in qemu-kvm (Ubuntu) (and 1 other project) "qemu-system-arm segfaults emulating versatile machine after running debootstrap --second-stage inside vm (affects: 1) (heat: 8)" [Medium,Triaged] https://launchpad.net/bugs/604872 | 13:31 |
| rsalveti | depends on what you're installing | 13:31 |
| rsalveti | sometimes it just get stuck and sometimes you'll get the segfault | 13:31 |
| furibondox | rsalveti: the latest from ubuntu repository | 13:31 |
| rsalveti | furibondox: you can try upstream version, I'm still fixing other bugs before releasing a new version | 13:32 |
| furibondox | from svn? | 13:32 |
| rsalveti | but you're still going to have the seg fault, the only difference is that it's going to try qemu more than once | 13:32 |
| rsalveti | furibondox: bzr | 13:32 |
| furibondox | ok | 13:32 |
| furibondox | I will try | 13:32 |
| rsalveti | bzr branch lp:project-rootstock | 13:33 |
| furibondox | I'm installing bzr | 13:34 |
| cwillu_at_work | rootstock reworked to use a chroot works great :) | 13:34 |
| furibondox | cwillu_at_work: using chroot instead of qemu???? | 13:35 |
| cwillu_at_work | furibondox, chroot with qemu-static | 13:35 |
| rsalveti | chroot with qemu | 13:35 |
| furibondox | ah ok | 13:35 |
| cwillu_at_work | it actually works spectacularly well :p | 13:35 |
| rsalveti | furibondox: the problem is that the additional packages are installed with apt-get | 13:36 |
| cwillu_at_work | as you can make use of as many cores as you have available, etc | 13:36 |
| rsalveti | with a full vm | 13:36 |
| cwillu_at_work | rsalveti, I reworked it to not use the vm at all beyond the chroot itself | 13:36 |
| rsalveti | so, if you're still getting lots of segfault, try installing ubuntu-minimal and then installs the rest at your board | 13:36 |
| rsalveti | cwillu: yeah, with root this is the best way | 13:37 |
| rsalveti | still need to take a better look at that | 13:37 |
| rsalveti | cwillu_at_work: gota a patch? | 13:37 |
| cwillu_at_work | not really; I've really had my way with the script | 13:37 |
| cwillu_at_work | actually, I guess alot of it would be patchable | 13:37 |
| furibondox | rsalveti: if I try to install ubuntu-minimal and then I create a script to install all the other packages I need and I call it with --script it should work? | 13:37 |
| rsalveti | yeah, don't worry, will take a better look at it later | 13:38 |
| cwillu_at_work | it's pretty straightforward though | 13:38 |
| rsalveti | yep | 13:38 |
| rcn-ee | it'll need some tweaks after the rootless changes.. ;) | 13:38 |
| rsalveti | rcn-ee: yep, but still somehow an easy change | 13:38 |
| rsalveti | furibondox: nops, because the script runs inside the vm | 13:39 |
| rsalveti | what you can do is to mount the filesystem, copy qemu static on it and chroot | 13:39 |
| rsalveti | then you are free to work on whatever you want | 13:39 |
| furibondox | ok | 13:39 |
| rsalveti | https://wiki.ubuntu.com/ARM/RootfsFromScratch | 13:39 |
| rsalveti | furibondox: see sing qemu user mode emulation (with chroot) | 13:40 |
| rsalveti | *using | 13:40 |
| furibondox | OK, however now I try with the latest bzr release | 13:41 |
| lag_ | ogra: Can you send me the line to make boot.scr please? | 14:05 |
| lag_ | mkimage *** | 14:05 |
| ogra | mkimage -A arm -T script -C none -n "Ubuntu boot script" -d <source> <target> | 14:05 |
| hrw | ogra: how many bytes does mkimage adds to initrd? | 14:18 |
| ogra | hrw, i think 64 ... one sec | 14:18 |
| ogra | hrw, 72 :) https://wiki.ubuntu.com/ARM/BeagleEditBootscr | 14:19 |
| * ogra knew he wrote that up somewhere | 14:19 | |
| hrw | thx | 14:19 |
| slangasek | ogra: ok, why does this not work?: dd if=/mnt/uInitrd skip=1 bs=72 | gunzip -c | cpio -t | 14:21 |
| lag_ | ogra: Cheers | 14:21 |
| ukleinek | ogra: a vanilla mkimage only adds 64, no? | 14:23 |
| ogra | slangasek, probably because -T ramdisk adds different stuff | 14:26 |
| ogra | ukleinek, might be, i think it varies with the comment (-n option) | 14:26 |
| slangasek | ogra: well, so how do I unpack it? :) | 14:27 |
| ogra | so the 72 might only be true if the comment is "Ubuntu boot script" | 14:27 |
| ukleinek | ogra: IIRC, no | 14:27 |
| ogra | slangasek, i never unpacked a uInitrd | 14:27 |
| slangasek | the comment is "Ubuntu Initrd" | 14:28 |
| ogra | ukleinek, funny, then i wonder why 72 works | 14:28 |
| ogra | slangasek, you flipped bs and skip options ? | 14:28 |
| ukleinek | http://git.denx.de/?p=u-boot.git;a=blob;f=include/image.h;h=bcc08d1a73224bb715d15983adea4767ce0e85fc;hb=HEAD#l176, 7*4 + 4 + 32 | 14:29 |
| slangasek | ogra: er, they're reversible | 14:30 |
| slangasek | except that the way I've done it gives better performance :) | 14:30 |
| slangasek | (and may spit a warning at the end due to a partial read) | 14:30 |
| lag_ | ogra: And the uimage mkimage script? (my 'useful commands' file is at home) | 14:58 |

| cooloney | rsalveti: thanks, actually, i don't have the HW for testing, | 15:15 |
| cooloney | rsalveti: can you test that lucid kernel? i did not prepare the maverick kernel | 15:16 |
| rsalveti | cooloney: I got it with lucid | 15:16 |
| rsalveti | didn't test maverick one yet | 15:16 |
| rsalveti | neither upstream | 15:16 |
| cooloney | rsalveti: cool, how's the result of lucid testing kernel? | 15:17 |
| rsalveti | cooloney: if you're at prague we cat probably give you one beagleboard so you can reproduce it | 15:17 |
| rsalveti | cooloney: same issue with latest lucid kernel, 2.6.33-502-omap | 15:18 |

| godstar | Hello | 19:27 |
| godstar | I am looking to install Ubuntu on a Archos 5 IT, any pointers? | 19:28 |
| loluengo | hi folks! | 20:09 |
| loluengo | i have a little question | 20:09 |
| loluengo | i'mm looking for a small system to begin with ubuntu/arm development | 20:10 |
| loluengo | i would like to have some advice | 20:10 |
| loluengo | which one you think is most suitable to begin?? | 20:11 |
| loluengo | beagleboard? or tincantools' hammer? | 20:12 |
| pcacjr | loluengo, beagleboard | 20:12 |
| loluengo | why? | 20:12 |
| loluengo | i mean... why pcacjr? | 20:12 |
| loluengo | any advantage? | 20:13 |
| pcacjr | hmm | 20:13 |
| pcacjr | it's simple to use | 20:13 |
| pcacjr | you could get the beagleboard C4 | 20:13 |
| pcacjr | it's a good hw | 20:13 |
| loluengo | i think the tincantools' nail kit is also very easy | 20:14 |
| pcacjr | loluengo, well i've only been hacking on beagleboard lately | 20:14 |
| pcacjr | loluengo, http://beagleboard.org is a good start | 20:15 |
| loluengo | and flyswatter for jtag progamming? | 20:15 |
| pcacjr | maybe :-), depends on you mate | 20:16 |
| pcacjr | heh | 20:16 |
| loluengo | any other not-so-expensive jtag emulator recommendation? | 20:18 |
| godstar | What image do I use to install Ubuntu on an ARM device? | 20:19 |
| loluengo | i looked at ti.com page and all of the emulator the recommend are VERY expensive! | 20:21 |
| prpplague | loluengo: it all depends on what you want to do | 20:23 |
| prpplague | loluengo: for alot of the basic operations of OMAP3 you don't really need a jtag | 20:24 |
| loluengo | prpplague, what do you mean by basic operations? | 20:25 |
| prpplague | loluengo: the OMAP3 has internal rom code that supports booting from SD card, uart, USB and nand flash | 20:25 |
| prpplague | loluengo: so jtag isn't really needed for initial bootloader programming | 20:26 |
| loluengo | prpplague, programming? debugging? tracing? | 20:26 |
| prpplague | loluengo: basic programming debugging can be done via uart or other I/O, but if you really need jtag, you can use something like the flyswatter with openocd | 20:27 |
| loluengo | hmmm | 20:27 |
| loluengo | that sounds like a great PLUS for beagleboard | 20:28 |
| loluengo | (over tincantools' hammer) | 20:28 |
| prpplague | loluengo: beagle and hammer aren't exactly in the same ball park | 20:29 |
| prpplague | loluengo: they are for different purposes | 20:29 |
| loluengo | prpplague, why do you say that? | 20:35 |
| loluengo | i see them similar | 20:35 |
| loluengo | both are arm-based boards | 20:35 |
| loluengo | both run linux | 20:35 |
| prpplague | loluengo: the hammer was designed as a hardware developers platform with limited resources | 20:35 |
| prpplague | loluengo: the beagle was designed as a software development platform with very little hardware expansion | 20:36 |
| prpplague | loluengo: they are vastly different target audience | 20:36 |
| prpplague | s/are/have | 20:36 |
| loluengo | aaahhh ok | 20:36 |
| loluengo | if i understood hammer is like a processor module - no peripherals added | 20:37 |
| loluengo | and beagleboard has plenty of peripherals, intended to develop software | 20:38 |
| prpplague | exactly | 20:40 |
| prpplague | loluengo: the hammer is available with some peripherals, but those are mainly for testing and reference for the developer | 20:40 |
| loluengo | good advice prpplague | 20:43 |
| loluengo | i think hammer is for me... | 20:43 |
| loluengo | my work is more hardware oriented than software oriented | 20:44 |
| prpplague | loluengo: is there something specific you are planning to work on? | 20:49 |
| loluengo | prpplague, yes... some kind of data logging device | 20:51 |
| prpplague | loluengo: ahh | 20:51 |
| loluengo | prpplague, not so interesting, but veeery useful | 20:52 |
