| Xofrats | hi, quick question, why does rootstock on karmic insist on qemu even when running under arm? | 10:24 |
|---|---|---|
| ogra_ | sigh, apachelogger had a boring sunday it seems | 11:43 |
| * ogra_ wades through bugmail | 11:44 | |
| === lilstevie|ZNC is now known as lilstevie | ||
| lilstevie | ogra: heh, any interesting bugs? | 11:55 |
| ogra_ | nah, just general noise | 11:56 |
| lilstevie | damn | 11:56 |
| lilstevie | you should see this weird bug I have had come up since switching to a newer kernel :p | 11:56 |
| apachelogger | ^^ | 11:57 |
| ogra_ | tell me | 11:57 |
| apachelogger | ogra_: more like proper triage :P | 11:57 |
| ogra_ | heh, yeah | 11:57 |
| lilstevie | the bootloader image is taking over, graphical corruption all round, | 11:57 |
| ogra_ | ouch | 11:57 |
| lilstevie | basically in samsungs 2.6.35 sourcedrop the fbdev driver has been royally screwed | 11:57 |
| ogra_ | yeah, sounds bad | 11:58 |
| lilstevie | my login screen is a few gdm elements overlayed over the bootsplash | 11:58 |
| ogra_ | did you try to roll back the driver ? | 11:58 |
| lilstevie | not yet | 11:58 |
| lilstevie | I will try that when I get back | 11:59 |
| lilstevie | brb | 11:59 |
| lilstevie | food | 11:59 |
| Xofrats | Hey, either of you familiar with rootstock? | 11:59 |
| Xofrats | I guess I killed the channel again | 12:02 |
| ogra_ | while i initially wrote rootstock i havent touched it in more than 12months | 12:03 |
| Xofrats | Well, close enough... I had a sorta-generic question | 12:04 |
| Xofrats | Is there a armel image that contains enough to run rootstock from a chroot setup? | 12:05 |
| Xofrats | Because most of the references I see refer to qemu this or that | 12:06 |
| * ogra_ has never run rootstock on arm ... and it wasnt originally created for that | 12:06 | |
| Xofrats | I can't even apt-get rootstock on karmic because it fails on qemu | 12:06 |
| ogra_ | iirc someone patched it to be able to run natively though, but i have zero experience with that | 12:07 |
| Xofrats | Hmmm.... | 12:07 |
| ogra_ | you shouldnt run karmic anyway | 12:07 |
| ogra_ | its EOL | 12:07 |
| Xofrats | I know, but that's the image I got to be able to run Ubuntu on an android phone | 12:07 |
| Xofrats | Linux localhost 2.6.32.9 #1 Sun May 22 19:44:33 CDT 2011 armv7l GNU/Linux | 12:08 |
| ogra_ | what HW is that ? | 12:08 |
| Xofrats | epic | 12:08 |
| ogra_ | ah, thats samsung, right ? | 12:09 |
| hrw | htc | 12:09 |
| Xofrats | Yeah | 12:09 |
| hrw | sorry | 12:09 |
| Xofrats | no. sammy | 12:09 |
| Xofrats | evo is htc | 12:09 |
| ogra_ | lilstevie has some samsung experience ... | 12:10 |
| Xofrats | k, good | 12:10 |
| Xofrats | I want to also sorta-resurrect rhodbuntu for xda soon | 12:10 |
| ogra_ | if you want a barebone image, take the omap preinstalled netbook image, grab the content of the second partiton and touch /var/lib/oem-config/run | 12:10 |
| Xofrats | hmm, k | 12:11 |
| ogra_ | tar it up and untar it on your phone | 12:11 |
| Xofrats | well, there lies the issue | 12:11 |
| ogra_ | or if you want it more minimal you can du the same with the headless image | 12:11 |
| Xofrats | this *is* my computer atm | 12:11 |
| ogra_ | *do | 12:11 |
| Xofrats | so right now karmic is chroot'ed and running epic4 which lets me be here | 12:12 |
| Xofrats | but I want to be able to create something a bit better | 12:13 |
| lilstevie | which device? | 12:14 |
| Xofrats | I just find it quite amusing that I can subsystem a true GNU/Linux on my phone | 12:14 |
| Xofrats | epic 4g | 12:14 |
| lilstevie | that is the same family as the i9000 isn't it | 12:14 |
| Xofrats | yeah | 12:14 |
| Xofrats | galaxys | 12:15 |
| Xofrats | only one with a keyboard | 12:15 |
| lilstevie | ok, if you give me a bit I will run through some of it with you, I have already gotten things working on the sgs i9000 | 12:15 |
| lilstevie | just no modem | 12:15 |
| Xofrats | I don't need modem, I just nice chroot /data/local/ubuntu /bin/sh | 12:16 |
| lilstevie | eh I don't chroot | 12:16 |
| Xofrats | Let android handle the hw... | 12:16 |
| lilstevie | chrooting is far from ideal, just fyi | 12:17 |
| Xofrats | I know | 12:17 |
| Xofrats | Trust me, I know | 12:17 |
| lilstevie | heh | 12:18 |
| lilstevie | I have a nice setup going, flash kernel and param with heimdall and throw the image on one of the SD cards | 12:18 |
| ogra_ | lilstevie, btw, how about providing your flash-kernel patch for upstream inclusion (or at least ubuntu inclusion) | 12:19 |
| Xofrats | I just use an ext4 kernel and loopmount the ubuntu image | 12:19 |
| lilstevie | ogra_: I dd | 12:19 |
| ogra_ | oh ? | 12:19 |
| lilstevie | ogra_: the kernel is stored in its own block device that the bootloader reads | 12:20 |
| lilstevie | a flash_kernel patch may help for easier updates including command line | 12:20 |
| ogra_ | yes | 12:20 |
| lilstevie | I'm still trying to figure exactly how but there is a socket in one of the closed source modules that allows writing direct to the non-volatile stash that bootloader params are stored in | 12:21 |
| Xofrats | how big is your sd image? | 12:21 |
| lilstevie | my SD image is 2GB | 12:21 |
| lilstevie | brb gotta do something so the mrs doesn't kill me | 12:22 |
| Xofrats | The current "linux" image is woefully inadequate | 12:23 |
| Xofrats | the guy that wrote the bootstrap script doesn't even know how to sed and cut | 12:24 |
| Xofrats | I got it to the point where it doesn't whine about fs and partiion layouts | 12:25 |
| Xofrats | but at least android uses the linux kernel to the point that you can chroot and run a gnu system under it | 12:27 |
| lilstevie | back, | 12:27 |
| lilstevie | I use an ubuntu initramfs in my kernels | 12:28 |
| lilstevie | after playing round with the compression managed to get a natty initramfs to fit too :) | 12:28 |
| Xofrats | nice | 12:29 |
| ogra_ | lilstevie, oh. you had compression issues ? | 12:29 |
| Xofrats | kernel now supports lz right? | 12:29 |
| lilstevie | ogra_: yeah the zImage was 8.3MB | 12:29 |
| ogra_ | lilstevie, what did you do ? | 12:30 |
| ogra_ | i have a similar prob on the ac100 | 12:30 |
| lilstevie | but the partition is just over 7 | 12:30 |
| lilstevie | I switched to lzma | 12:30 |
| Xofrats | thought so | 12:30 |
| Xofrats | lz is great except it's a memory hog | 12:30 |
| ogra_ | hmm, doesnt help here | 12:31 |
| * ogra_ already tried all possible compression methods | 12:31 | |
| lilstevie | gzip gave me an 8.3MB kernel | 12:31 |
| lilstevie | lzo gave me 10mb | 12:31 |
| lilstevie | lzma is just fitting weighing in at 6.9MB | 12:31 |
| Xofrats | everytime someone posts something in 7z I can't decompress half cuz the dictionary is too big | 12:31 |
| lilstevie | ogra_: how big is your partition | 12:32 |
| ogra_ | 8M | 12:32 |
| lilstevie | hmm | 12:32 |
| lilstevie | why so big then? | 12:32 |
| ogra_ | but for a full fastboot boot.img | 12:32 |
| lilstevie | do you need to mkboot | 12:32 |
| ogra_ | the kernel is 3.5M | 12:32 |
| ogra_ | so i only have 4.5 left | 12:33 |
| lilstevie | the samsung bootloader takes a raw vmlinux | 12:33 |
| lilstevie | or zImage | 12:33 |
| ogra_ | ah, lucky you | 12:33 |
| ogra_ | ac100 uses a fastboot img file to boot ... i need to pre-process kernel and initrd | 12:34 |
| lilstevie | I also have a serial shell with the bootloader | 12:34 |
| ogra_ | using abootimg | 12:34 |
| ogra_ | no serial port here | 12:34 |
| lilstevie | eugh, I am not looking forward to that with the transformer | 12:34 |
| ogra_ | so a console wouldnt help much | 12:34 |
| ogra_ | yep | 12:34 |
| ogra_ | well, should be easy | 12:34 |
| lilstevie | heh yeah, going to be kernel level for most of it | 12:35 |
| ogra_ | i guess it shouldnt take more than one/two days to get a first cut image running | 12:35 |
| lilstevie | yeah thats how long I give it | 12:35 |
| lilstevie | it is being sent tomorrow, | 12:35 |
| ogra_ | properly integrated rather a week or two | 12:35 |
| ogra_ | (depending on the kernel) | 12:35 |
| lilstevie | but when it gets here I forsee booting within the hour | 12:35 |
| lilstevie | I am going to be getting on ASUS ass about GPL | 12:36 |
| ogra_ | the kernel source is there | 12:36 |
| lilstevie | they still haven't released the 3.1 kernel source | 12:36 |
| ogra_ | question is how the nvidia bits are integrated | 12:36 |
| lilstevie | much like the xoom | 12:37 |
| lilstevie | from what I have looked over so far in the 3.0 source | 12:37 |
| ogra_ | if transformer uses nvec as badly as ac100 it will be really really bad to get the peripherials working | 12:37 |
| lilstevie | yeah I hope not :/ | 12:37 |
| ogra_ | they all need undocumented init codes from nvec here | 12:37 |
| lilstevie | are nvidia willing to cooperate? | 12:37 |
| ogra_ | so for ac100 it took nearly 6 months to get that properly worked out | 12:37 |
| lilstevie | I take it not | 12:37 |
| ogra_ | nvidia ? | 12:38 |
| ogra_ | lol | 12:38 |
| lilstevie | heh well their SoC is horribly documented | 12:38 |
| ogra_ | i think the devs would love to ... but management doesnt care | 12:38 |
| lilstevie | heh | 12:38 |
| lilstevie | samsung are actually taking a big interest in OSS which has been a huge plus | 12:38 |
| Xofrats | stevie: do you think using rootstock is the best way to create a new image? | 12:38 |
| ogra_ | just getting their 3D driver in a binry form like the x86 one would change the world | 12:39 |
| lilstevie | I have been using the omap4 prebuilt | 12:39 |
| Xofrats | didn't they just send a few 'pad to kernel hackers? | 12:39 |
| Xofrats | hmm, k | 12:39 |
| lilstevie | yeah they sent a 10.1 to supercurio | 12:39 |
| Xofrats | and natty works on the galaxy? | 12:40 |
| Xofrats | and I think karmic was the last one to support arm6 correct? | 12:41 |
| hrw | yes | 12:43 |
| hrw | (karmic) | 12:43 |
| lilstevie | it is much harder galaxy s is armv7 | 12:43 |
| lilstevie | 'er | 12:43 |
| lilstevie | shouldnt stop half way in :p | 12:44 |
| lilstevie | galaxy s is an armv7 device, cortex-a8 | 12:44 |
| Xofrats | Well, gonna use natty on the epic | 12:44 |
| lilstevie | ogra_: 3D drivers are something we wish for here too | 12:45 |
| Xofrats | But I also want to do something similar for the msm7k2 | 12:45 |
| Xofrats | which is arm6 | 12:45 |
| ogra_ | lilstevie, well, the nvidia ones exist ... but they are linked and built against unusable xorg versions | 12:45 |
| Xofrats | memory might be an issue though | 12:45 |
| ogra_ | so you can onyl use them if you also replace half your rootfs | 12:45 |
| lilstevie | ogra_: while I can try hijacking the tiomap SGX drivers my gpl-glue is horrible and doesn't support DRI | 12:46 |
| lilstevie | ew | 12:46 |
| ogra_ | you should talk to jessebarkers team in #linaro :) | 12:46 |
| lilstevie | why would they do that | 12:46 |
| lilstevie | for the module? | 12:46 |
| Xofrats | would omap4 be the right one for karmic too? | 12:47 |
| lilstevie | I've been chipping away at patching in the samsung stuff to the DKMS but it has been a slow process | 12:47 |
| ogra_ | the module isnt the prob, the xerver is | 12:48 |
| ogra_ | i can roll a kernel that ignores all versioning info from that module | 12:48 |
| ogra_ | but i cant run userspace without the right xlibs | 12:48 |
| lilstevie | well when I say I use the omap4 image, I use the rootfs, rip out all the omap stuff and replace with hummingbird modules and firmwares | 12:49 |
| ogra_ | dont use omap4 :) | 12:49 |
| ogra_ | use omap | 12:49 |
| lilstevie | ah you mean for the ULP GeForce | 12:49 |
| lilstevie | what is the difference | 12:49 |
| ogra_ | omap4 has the PPA bits | 12:49 |
| lilstevie | ah | 12:49 |
| ogra_ | so you have a few pieces more to remove to get back to a clean image | 12:50 |
| lilstevie | I used the omap4 image cause hardware wise it is closest, ie: same GPU :p | 12:50 |
| ogra_ | on omap you can just dpkg -l |grep omap and remove all the bits | 12:50 |
| lilstevie | ah nice | 12:50 |
| Xofrats | okay | 12:51 |
| Xofrats | what's ppa, sorry | 12:51 |
| lilstevie | Personal Package Archives | 12:53 |
| Xofrats | k | 12:53 |
| * ogra_ actually hopes someone from the nouveau people will develop some interest in tegra | 12:54 | |
| lilstevie | ogra_: I really hope that the keyboard dock for the transformer doesn't need undocumented shit implemented in nvec to work | 12:55 |
| lilstevie | that would be a massive failure | 12:55 |
| ogra_ | well, that would be what i expect though :) | 12:56 |
| ogra_ | from nvidia | 12:56 |
| Xofrats | how different is the omap prebuilt to say rootstock-based image? | 12:56 |
| ogra_ | it uses a diffrerent build system | 12:56 |
| lilstevie | ogra_: lets just hope asus took a bit more control for their dock | 12:57 |
| ogra_ | we'll see | 12:57 |
| Xofrats | any pro/cons to either, or am I being a n00b | 12:58 |
| ogra_ | well, prebuilt gives you a read made system, rootstock *creates* a system | 13:00 |
| ogra_ | and given that you cant run it natively apparently, i dodnt really see where you have choice ;) | 13:01 |
| lilstevie | eugh, looking at the sources it appears the dock is interfaced through NVIDIA Tegra internal matrix keyboard controller | 13:02 |
| Xofrats | yeah, true | 13:02 |
| ogra_ | sounds like nvec | 13:03 |
| plm | Are there plans to support tegra? | 13:05 |
| ogra_ | no, but there will be an ac100 community image | 13:07 |
| ogra_ | and probably also one for the eeepad tarnsformer | 13:07 |
| ogra_ | *trans | 13:07 |
| Xofrats | how much ram is considered decent for arm-based sytem? | 13:07 |
| ogra_ | there wont be official tegra support from ubuntu though | 13:07 |
| ogra_ | Xofrats, 512M works ... i wouldnt even start trying with anything less | 13:08 |
| lilstevie | hopefully my eeepad arrives this week | 13:08 |
| lilstevie | 512 is ok | 13:08 |
| Xofrats | hmmm, ew... | 13:08 |
| Xofrats | wonder how rhodbuntu got it working with 200 | 13:08 |
| lilstevie | I am actually thinking of cramfs | 13:08 |
| ogra_ | Xofrats, cutting out tons of stuff | 13:09 |
| ogra_ | Xofrats, my ac100 uses 130MB for teh desktop on start | 13:09 |
| ogra_ | as you can see you can indeed use that on 200M | 13:09 |
| ogra_ | just dont start any app ;) | 13:09 |
| Xofrats | I guess | 13:10 |
| Xofrats | But in this case it'll be sharing memory space with *ndr**d | 13:10 |
| lilstevie | yeah I use about 150MB on boot with the tab | 13:10 |
| ogra_ | using a browser with 20tabs open, xchat with about 30 channels on several servers, a bunch of terminals and evolution via ssh -X from another machine i use 380M ram and 250M swap here | 13:11 |
| Xofrats | 20 tabs... | 13:11 |
| ogra_ | according to htop | 13:11 |
| plm | ogra_: why wont be official tegra support from ubuntu? any special subject? | 13:12 |
| Xofrats | I don't need much for gui from ubuntu anyway | 13:13 |
| ogra_ | no collaboration with nvidia atm | 13:13 |
| lilstevie | ogra_: k maybe it doesn't I am looking in the wrong config block | 13:13 |
| Xofrats | tons of useful console/ncurses app to use | 13:13 |
| Xofrats | strobe, ping -f... | 13:14 |
| plm | ogra_: wow, nvidia is so close.. :-( | 13:14 |
| Xofrats | oh wait, wrong hat *switches hat* | 13:14 |
| ogra_ | plm, but there are a bunch of community projects for specific devices | 13:14 |
| ogra_ | plm, so we will have community images on cdmiang for some | 13:15 |
| ogra_ | *cdimage | 13:15 |
| plm | ogra_: yes, I know about OMAP3/4 of TI.. | 13:15 |
| ogra_ | i.e. toshiba ac100 ... probably the transformer, likely the nook color | 13:15 |
| plm | ogra_: like as pandaboard, bealge ans so one.. | 13:15 |
| ogra_ | they are official images | 13:15 |
| ogra_ | panda and the omap3 ones are fully supported by canonical | 13:16 |
| ogra_ | the tegra2 ones wont be | 13:16 |
| lilstevie | ogra_: how does one go about getting a community image on cdimage | 13:16 |
| ogra_ | lilstevie, we just work on documenting that | 13:17 |
| plm | ogra_: yes.. I would like to use tegra3.. and I would like know if are a there (i not found) a community project for tegra3 like as are there with panda.. | 13:17 |
| ogra_ | for now you need to work with a person from the cdimage team (or be in that team) | 13:17 |
| lilstevie | ah ok | 13:17 |
| ogra_ | lilstevie, though it all starts with having a kernel package in universe | 13:17 |
| ogra_ | plm, i dont think you can get tegra3 HW aynwhere yet | 13:18 |
| ogra_ | so there is no community for it yet | 13:18 |
| plm | ogra_: ok.. but not for tegra2 too :-( | 13:18 |
| ogra_ | well, for tegra2 the above applies | 13:19 |
| lilstevie | ogra_: ah ok, well my galaxy kernel is nowhere near that standard yet | 13:19 |
| ogra_ | ac100 images will be there for oneiric | 13:19 |
| ogra_ | lilstevie, what standard ? | 13:19 |
| ogra_ | its universe | 13:19 |
| lilstevie | ogra_: my standard | 13:19 |
| plm | ogra_: above? | 13:19 |
| ogra_ | lilstevie, if it doesnt remove all your user data from the HDD and makes most devices work it should be enough | 13:20 |
| plm | ogra_: what is that ac100 ? | 13:20 |
| ogra_ | indeed if you have a "wipe my disk" bug you ship, thats below any standard :) | 13:20 |
| plm | ogra_: I'm looking for in https://wiki.ubuntu.com/ARM | 13:20 |
| ogra_ | plm, toshiba ac100 netbook | 13:20 |
| ogra_ | yeah, persia wanted to add a page for tegra/ac100 ... apparently thats not there yet | 13:21 |
| Xofrats | Mine comes with "nuke from orbit" and locks onto my agps chip | 13:21 |
| Xofrats | does that count? | 13:21 |
| plm | ogra_: ok.. well.. notebook is so big.. I would like to use power of GPUs but in a little device.. like as omap with dsp... | 13:22 |
| lilstevie | ogra_: my standard means it works and can be used | 13:22 |
| ogra_ | lilstevie, well, if it does that, roll a package from it :) | 13:23 |
| lilstevie | by can be used I mean modem and all | 13:24 |
| lilstevie | and modem is far from even close to booting | 13:24 |
| lilstevie | ogra_: the more I look at the source for the eeepad the more it looks like it is going to be done in nvec | 13:28 |
| Xofrats | anyway, thanks for the info, I'll prolly be back with more n00b q | 13:33 |
| lilstevie | welcome back ogra | 13:52 |
| jeremiah | w00t! The oneiric daily build from today is booting on the OMAP 4 pandaboard :) | 15:05 |
| ogra_ | funny, given that there was no build today | 15:07 |
| ogra_ | oh, wait, you mean headless | 15:08 |
| jeremiah | ogra_: Yeah, the headless version. :) | 15:09 |
| jeremiah | Still going through some filesystem checks at the moment. | 15:09 |
| ogra_ | yeah, netbook wouldnt be much fun atm | 15:09 |
| ogra_ | given that the whole USB stack seems to be screwed in the current kernel | 15:10 |
| jeremiah | Ah. | 15:10 |
| jeremiah | That sounds, um, painful. | 15:10 |
| lool | ogra_: hey | 15:14 |
| lool | ogra_: how much do you use qemu-system-arm with versatile kernels these days? | 15:14 |
| ogra_ | lool, me ? | 15:14 |
| lool | ogra_: you | 15:14 |
| ogra_ | i havent used that since two releases iirc | 15:14 |
| lool | Ok; thanks :-) | 15:15 |
| ogra_ | rootstock still uses it though | 15:15 |
| ogra_ | should be ported to omap or some such | 15:15 |
| lilstevie | heh | 15:15 |
| noah1989 | hi | 15:17 |
| noah1989 | where can i browse the packages available for ARM architectures? | 15:18 |
| noah1989 | packages.ubuntu.com seems to have amd64 and i386 only | 15:18 |
| ogra_ | launchpad | 15:20 |
| ogra_ | generally you can say though that the source package list doesnt differ between x86 and armel, apart from very few arch specific packages like bootloaders | 15:21 |
| ogra_ | http://qa.ubuntuwire.org/ftbfs/natty.html has a list of binaries that didnt build on arm | 15:22 |
| ogra_ | everything else is available on armel as well as on i386 | 15:22 |
| noah1989 | ah.. that's fine | 15:26 |
| jeremiah | http://pastie.org/2096114 | 15:28 |
| jeremiah | Hmm, OMAP 4 headless image hangs there ^^ | 15:28 |
| ogra_ | how big is your SD ? | 15:30 |
| ogra_ | the actual write of the resizing happens after that line, it might take a moment with bigger SDs | 15:30 |
| jeremiah | 8 gigs | 15:30 |
| ogra_ | (you should see the LEDs being busy though) | 15:30 |
| jeremiah | Both LEDS are busy | 15:31 |
| jeremiah | :) | 15:31 |
| ogra_ | good | 15:31 |
| ogra_ | then just give it time | 15:31 |
| jeremiah | Will do. | 15:31 |
| ogra_ | lool, yre you planning to drop versatile completely or just the v7 patch ? | 15:49 |
| lool | ogra_: drop it completely | 15:50 |
| ogra_ | good | 15:51 |
| lool | ogra_: essentially, vexpress should be better in all respects | 15:51 |
| ogra_ | in aemu respects too ? :) | 15:51 |
| lool | I'm using vexpress these days, and it's buggy, but I believe the same code is used for versatile, so it should be the same really | 15:51 |
| ogra_ | *qemu | 15:51 |
| lool | Yes; AFAIK it's using the same QEMU drivers | 15:51 |
| lool | for SD, fb etc. | 15:51 |
| ogra_ | ah, awesome | 15:51 |
| lool | but it's not much usable sadly | 15:52 |
| lool | the network corrupts or cuts some packets somehow | 15:52 |
| ogra_ | worse than versatile ? | 15:52 |
| lool | and the SD stalls regularly | 15:52 |
| lool | I don't think it's worse than versatile | 15:52 |
| ogra_ | k | 15:52 |
| lool | oddly, using a Debian userspace makes things better | 15:52 |
| lool | not perfect, but better | 15:52 |
| lool | I think it's just an accident though | 15:52 |
| ogra_ | yeah, i heard the same for the ac100 port, people using debian have less kernel issues it seems | 15:53 |
| jeremiah | heh, that reminds me. I want to get debian working on my AC 100 | 15:53 |
| ogra_ | (we have a kernel bug that makes input devices die, apparently that shows only very rarely on debian userspace with the same kernel binary) | 15:53 |
| ogra_ | (and with similar userspace) | 15:53 |
| ogra_ | jeremiah, just bootstrap a rootfs :) | 15:54 |
| jeremiah | Cool, I'll do that. :-) | 15:55 |
| lilstevie | ogra_: actually something I haven't been able to get straight about the tegra2 | 15:57 |
| lilstevie | where does APX exist | 15:57 |
| lilstevie | bootloader, or bootrom | 15:57 |
| ogra_ | APX ? | 15:58 |
| lilstevie | the mode that nvflash talks to | 15:59 |
| alex12 | greetings all. Anyone have a moment to help me out with an ubuntu 11.04 installation on beagleboard-xm rev C? | 15:59 |
| ogra_ | in the ac100 thats in rom i think | 16:01 |
| lilstevie | hm cool, I am just wondering about flashing risk, etc. if I fuck a flash on the tab when it is doing the bootloader, I am pretty much left with jtag as my only option, other than taking it to samsung | 16:02 |
| ogra_ | well, if it is set up similar to the ac100 you cant brick it | 16:02 |
| GrueMaster | alex12: what issues are you having? | 16:03 |
| ogra_ | even if i screw up the MMC completely i can always get it into flash mode and re-do everything | 16:03 |
| lilstevie | ok thats what I wanted to hear | 16:03 |
| lilstevie | I bricked my tab once, :/ | 16:03 |
| ogra_ | thats why i think its in ROM | 16:03 |
| hrw | lilstevie: define 'bricked' | 16:03 |
| lilstevie | ogra_: ok, that tells me what I want to know | 16:04 |
| lilstevie | hrw: as in it was a paper weight | 16:04 |
| lilstevie | hrw: full definition of brick | 16:04 |
| alex12 | I used canonical's pre-built 11.04 image. Followed instructions to replace uImage and the kernel on the sd-card. Booted the bb-xm rev. c. and a.)colors are off (everything is red) b.) no mouse or keyboard response at the first set-up screen. can't go anywhere. any ideas? | 16:04 |
| lilstevie | returned to samsung to fix | 16:04 |
| GrueMaster | alex12: Which image? Netbook or headless? | 16:05 |
| alex12 | netbook | 16:05 |
| GrueMaster | hmmm. Haven't heard of that issue offhand. Unfortunately I don't have one of these newer boards to test with. | 16:05 |
| alex12 | okay thanks for your time. i'm going to try the 10.10 pre-built now. | 16:06 |
| hrw | lilstevie: nice | 16:07 |
| lilstevie | hrw: nice that I am not misusing the term, or nice that the device can be permafucked | 16:08 |
| lilstevie | ? | 16:08 |
| noah1989 | lilstevie: i think he meant "nice" how precisely you defined the term | 16:11 |
| lilstevie | heh | 16:12 |
| hrw | yes | 16:13 |
| hrw | as lot of people say 'bricked' as 'had to reflash' | 16:13 |
| lilstevie | heh soft-brick | 16:14 |
| noah1989 | the correct definition of "bricked" depends on the equipment that you have available | 16:16 |
| noah1989 | for example an AVR microcontroller can be bricked by disabling the ISP programming interface, but that's only for people who don't have a 12V parallel programmer and a soldering iron | 16:17 |
| ogra_ | so its not bricked :) | 16:17 |
| ogra_ | bricked for me means something you cant fix ... its a brick | 16:18 |
| noah1989 | well that depends on wether "you can't" means "you're unable" or "it's impossible" | 16:19 |
| ogra_ | the latter | 16:19 |
| lilstevie | my tab required a new logic board | 16:19 |
| hrw | bricked == have to use jtag or worse - for me | 16:23 |
| lilstevie | hrw: agreed | 16:24 |
| hrw | especially when I lack jtag at home ;D | 16:25 |
| lilstevie | I define bricked as fubar'd | 16:25 |
| lilstevie | yeah my jtag does not work on the tab | 16:25 |
| * ogra_ is happy he doesnt have to work with HW you can actually brick atm | 16:25 | |
| ogra_ | and i hope that wont change :) | 16:26 |
| lilstevie | heh | 16:26 |
| lilstevie | samsung screwed something with iROM by not giving a method of halting boot to get into a bootrom recovery | 16:26 |
| ogra_ | bitter | 16:27 |
| alex12 | did my bb-xm just die? I have the 5V adapter (from digikey, recommended supply). just powered on, all I'm getting is the D5 LED solid green, no other activity... | 16:48 |
| GrueMaster | Do you have an SD plugged in? | 16:51 |
| alex12 | yes | 16:52 |
| ogra_ | sounds like bootloader or kernel screwup | 16:52 |
| alex12 | okay i'll reimage the SD card, thanks! | 16:52 |
| rsalveti | lool: how much mem qemu currently supports for vexpress? 1gb? | 17:47 |
| ogra_ | thats what he wrote in the mail | 17:50 |
| alex12 | i'm using bb-xm demo image of ubuntu (netbook-minimal-11.04). after doing an apt-get update, I used 'apt-get install ssh' to install the meta-package. ubuntu was in the middle of it when DVI image just went dead... same thing happened the other evening when trying to install xfce. any ideas why i'd lose video? | 17:51 |
| ogra_ | a bug ? | 17:57 |
| ogra_ | (would be my first idea) | 17:57 |
| ogra_ | :) | 17:57 |
| lool | rsalveti: yes | 18:09 |
| lool | alex12: could be a power issue too; if you're powering from USB for instance, driving a DVI device + USB + stuff is too much | 18:10 |
| alex12 | lool: thanks, i'll move a device off then | 18:11 |
| alex12 | rcn-ee: thanks for the bb-xm demo image, first time I've been able to get Ubuntu to come alive on my board =) | 18:44 |
| rcn-ee_at_work | cool, your welcome alex12 | 18:48 |
| alex12 | rcn-ee_at_work: so, any ideas why the canonical images don't run right on the -xM rev. C? I know you've been developing the alternatives for quite a while now... canonical still can't keep up? I followed all their instructions, replaced the kernel (which is presumably something similar to what you've done) but I cannot get it to boot. =( Why can't they get it straight? | 18:50 |
| GrueMaster | alex12: Don't blame us. We have a hard time when board revs change functionality and we aren't informed until users complain. And we don't have them to test/debug. | 18:57 |
| rcn-ee_at_work | alex12, the xM C kinda came out suddenly, i was luckly enough to get one early at a ti training, but by that time it was too late for ubuntu's natty.. the kernel's image was frozen.. with my images, i don't have that limiation.. | 19:00 |
| sveinse | Is it possible to run update-initramfs from within a chroot environment? I got "/bin/df: Warning: cannot read table of mounted file systems: No such file or directory" | 19:25 |
| ogra_ | yes, but you need to bind mount /dev from outside the chroot and proc and sys inside the chroot | 19:26 |
| sveinse | Note The chroot is not for the same machine as the running machine | 19:26 |
| ogra_ | well, it still uses /dev/null and stuff | 19:27 |
| sveinse | Interestingly the rootstock script mounts proc and devpts from outside the chroot | 19:28 |
| ogra_ | hmm ? | 19:29 |
| sveinse | iirc that is | 19:29 |
| ogra_ | i dont think so | 19:29 |
| ogra_ | it should chroot | 19:29 |
| ogra_ | unless someone really mangled my original code | 19:30 |
| sveinse | It has been changed | 19:30 |
| sveinse | never the less, what significance are there concerning mounting proc and sys from the inside? | 19:31 |
| ogra_ | the scripts looks at files in there | 19:31 |
| ogra_ | *look | 19:32 |
| sveinse | But there's no real difference between mounting proc before running chroot than mounting it afterwards, is there? | 19:32 |
| ogra_ | no | 19:32 |
| sveinse | good | 19:32 |
| ogra_ | doesnt matter how you mount it, as long as it is populated inside the chroot when you run your command | 19:33 |
| sveinse | yes. And in that context, the rootstock script only mounts proc and devpts, not dev | 19:34 |
| sveinse | Wait a minute, isn't device nodes, like /dev/null, blk nodes, so they dont need /dev as mount to work, or am I misunderstanding? | 19:35 |
| ogra_ | null is a char device | 19:36 |
| sveinse | yeah, but still a device node, so if it exists on the fs it will work. It don't need some mounted /dev | 19:37 |
| ogra_ | i dont know which devices update-initramfs needs | 19:37 |
| ogra_ | null was just an example, just mount it | 19:37 |
| sveinse | Thanks | 19:39 |
| sveinse | There were some talk some time ago about altering update-initramfs to suit uboot image file format. Has this been made? | 19:44 |
| ogra_ | surely not | 19:45 |
| ogra_ | update-initramfs shouldnt have anything to do with handling bootloader specific bits | 19:45 |
| ogra_ | thats the job of flash-kernel in ubuntu/debian | 19:45 |
| ogra_ | (on arm at least) | 19:46 |
| sveinse | But some apt upgrade packages triggers update-initramfs which in turn needs to trigger uboot changes, right. | 19:46 |
| ogra_ | yes | 19:46 |
| ogra_ | so update-initramfs makes a call to flash-kernel | 19:46 |
| ogra_ | after it rolled the new initrd | 19:47 |
| sveinse | does flash-kernel handle uSD cards as well? | 19:47 |
| ogra_ | it handles whatever was set up for your board in the flash-kernel code :) | 19:48 |
| ogra_ | flash-kernel is a pretty horrid script wheer every board cooks its own soup, even if that means to duplicate half the code | 19:49 |
| sveinse | hmm. I see how flash-kernel is setup to be called from initram-fs. It's perhaps easier to just make my small little script to do this part | 19:50 |
| ogra_ | just add a patch to flash-kernel ... | 19:50 |
| ogra_ | and give it to me so i can include it in oneiric ;) | 19:51 |
| * ogra_ needs to do some real life stuff now ... | 19:54 | |
| sveinse | How should /etc/fstab look like on OMAP3? Mine is empty. (I refer to non-storage lines, like proc tmpfs etc.) | 20:20 |
