| ZeZu | Are there any known usb-storage issues on natty/pandaboard ? I have all sorts of interesting issues w/ various chipsets I use in linux/windows on a regular basis, the JM20336 always drops fairly soon after plugging it in, the CY7C68300A normally works but drops sometimes as well ( have rootfs on it so thats troublesome ) ... another gives an error and disables all URBs and never works | 01:31 |
|---|---|---|
| ZeZu | the jmicron chipset gets a reset then tells me the device offlined, not ready after error recovery | 01:37 |
| ZeZu | Seems like it might just not like the SSD connected.. | 01:43 |

| Jef91 | Anyone know a solid guide for getting an ARM system running in qemu? | 02:33 |
| jburkholder1 | Jef91: https://wiki.ubuntu.com/ARM/RootfsFromScratch | 02:45 |
| Jef91 | I've got that, when I try to launch the qemu I'm only getting a black screen | 02:46 |
| jburkholder1 | did you try the chroot? | 02:48 |
| jburkholder1 | IIRC both the system emulator and userspace emulator worked last time I tried | 02:48 |
| persia | What are you trying to do with the emulator? | 02:49 |
| Jef91 | just launch the system | 02:53 |
| Jef91 | I'm launching "qemu-system-arm -M versatilepb -cpu cortex-a8 -kernel ./vmlinuz-lucid -hda arm.img -m 256 -append "root=/dev/sda mem=256M devtmpfs.mount=0 rw" | 02:53 |
| Jef91 | " | 02:53 |
| persia | Oh, I meant at a much higher level. There's been a few people by who wanted to do stuff and it turned out the stuff they wanted to do didn't require the emulator they thought it might initially. | 02:54 |
| persia | That ought work. | 02:54 |
| Jef91 | I want to create a full root FS | 02:55 |
| Jef91 | want to build some packages in the ARM arch. as well for a repo | 02:55 |
| persia | If you have hardware, I'd recommend doing the building there. | 02:57 |
| persia | If you don't have hardware, I'd suggest using sbuild or pbuilder with a cross-chroot, and not running full qemu. | 02:57 |
| Jef91 | I'd like to do it in a full qemu as I'm going to be building a rootfs from it eventually | 02:58 |
| persia | You plan to build a rootfs based on the deritus of the environment in which you've been running builds? | 03:00 |
| Jef91 | No I plan to have two environments | 03:01 |
| persia | A build environment and a target environment, for deployment? | 03:02 |
| Jef91 | Correct. | 03:02 |
| Jef91 | Thats a good idea right? | 03:03 |
| persia | OK. So, for the build environment, I'll recommend *not* using qemu's system emulation, and just use the syscall emulation with pbuilder or sbuild's cross-chroot support. | 03:04 |
| Jef91 | Alrighty - noted. | 03:04 |
| persia | That's more likely to have been tested (yes, it's noisy about some things, but still). | 03:04 |
| Jef91 | I still need a qemu though | 03:04 |
| Jef91 | for setting up a depolyment system | 03:04 |
| persia | For testing, or for chroot creation? | 03:05 |
| Jef91 | Both I would think | 03:05 |
| persia | In my experience, running on hardware and running in qemu have surprisingly different performance characteristics. | 03:07 |
| persia | One of the key bits is that most Ubuntu environments end up not being able to run with the 256M of memory available to qemu's versatilepb environment. | 03:07 |
| Jef91 | I don't care about performance | 03:08 |
| Jef91 | I just want to physically setup the system | 03:08 |
| Jef91 | in a qemu | 03:09 |
| persia | And there was recently a debate about how to generate rootfs images for production in this channel, in which the consensus seemed to be "get some hardware". If you're playing, rootstrap or qemu-debootstrap or multistrap or debootstrap in an emulator can all work, but nobody seemed confident about standing behind any of them. | 03:09 |
| persia | Ah. If you really want to use qemu, then you have to use qemu to do that :) In which case, the instructions on the page already mentioned are supposed to work. | 03:10 |
| Jef91 | I have to run for now - and I am aware they are "suppose" to work. | 03:10 |
| Jef91 | If they did in fact work for me though, I wouldn't be here ;) | 03:10 |
| Jef91 | I guess I'll be back later when hopefully someone can help :-/ | 03:10 |
| === Jef91 is now known as Jef91|AFK | ||
| Jef91|AFK | Thanks for your input persia | 03:11 |
| persia | Sorry I'm not able to help you reach your goal. | 03:11 |
| jburkholder1 | blank screen might be because the console is not going to the right place | 03:12 |
| persia | I thought console went to qemu console by default. | 03:14 |
| persia | (which may not be the default shown in the SDL window) | 03:15 |
| jburkholder1 | the kernel might be using the serial port though | 03:18 |
| jburkholder1 | I seem to remember having to fool with redirecting the serial port to stdout to see the console messages | 03:18 |
| jburkholder1 | either with -nographic or -serial stdio qemu options | 03:24 |
| jburkholder1 | building a toolchain in the system emulator took forever so I switched to the chroot environment | 03:28 |
| === Jef91|AFK is now known as Jef91 | ||
| Jef91 | Howdy folks - so I'm trying to setup an Ubuntu rootfs through qemu and I've followed the guide posted here https://wiki.ubuntu.com/ARM/RootfsFromScratch and when it gets to the step of launching the VM all I get is a black screen. Ideas? | 04:46 |
| jburkholder1 | Jef91: have you tried -nographic? | 05:07 |
| Jef91 | ahh I have not | 05:09 |
| Jef91 | let me try that - one moment | 05:09 |
| jburkholder1 | if that doesn't work try setting the console to serial by passing console parameter to the kernel | 05:10 |
| jburkholder1 | console=ttyAMA0 (this is what I found in google) | 05:11 |
| Jef91 | how do I pass the console argument to the kernel? | 05:12 |
| jburkholder1 | and then you might have to use qemu -serial option to get the serial output on stdio | 05:12 |
| jburkholder1 | with the -append qemu option | 05:13 |
| jburkholder1 | -append "console=ttyAMA0" | 05:13 |
| jburkholder1 | seems that and -nographic should work | 05:14 |
| Jef91 | alrighty | 05:15 |
| Jef91 | setting up something else atm - will try in a few | 05:15 |
| Jef91 | thanks! | 05:15 |
| jburkholder1 | no problem, I'm off to sleep | 05:15 |

| ppisati | ogra_: can i use ac100's internal flash for ubuntu installation? or just usb/sd? | 16:36 |
| ogra_ | ppisati, i would recommend the internal, its the fastes disk you can get on the device (and its not actually fast ...) | 16:36 |
| ogra_ | ppisati, what model did you get ? | 16:37 |
| ppisati | ogra_: 10Z | 16:37 |
| ogra_ | (its written on the bottom) | 16:37 |
| ppisati | 8GB | 16:37 |
| ogra_ | ah, the same as GrueMaster then | 16:37 |
| ppisati | and i didn't update to 2.2 | 16:37 |
| ogra_ | he has massive probs with his ... | 16:37 |
| ppisati | oh sh*t... | 16:37 |
| ogra_ | i hope this is a GrueMaster thing | 16:37 |
| GrueMaster | hey! | 16:38 |
| ogra_ | he has a hand to actually run into strange bugs nobody else gets | 16:38 |

| gfunk | I have a noob question. Can I install ubuntu lucid on an Apple TV 2nd generation witch I believe has an ARM Cortex A-7 | 20:08 |
| gfunk | I found the device support page here https://wiki.ubuntu.com/ARM/DeviceSupport but I don't see the ATV2 | 20:11 |
| GrueMaster | If you can get a kernel & bootloader for it, it should be able to run Ubuntu. I would go with Natty over Lucid as there is more supported apps and better stability. | 20:16 |
| GrueMaster | I suggest looking for someone that has Ubuntu running on an iPad. | 20:17 |
| gfunk | Thanks for the response Grue | 20:21 |
| gfunk | Does the iPAD run the Cortex-8 or 9? | 20:21 |
| GrueMaster | A8 I think. | 20:21 |
| GrueMaster | I don't know. It isn't something we are actively working on and I don't know of any hacks to get it working off hand. | 20:22 |
| gfunk | Are there any natty guides where I can start on a custom kernel & bootloader build? | 20:23 |
| gfunk | i have built custom x86 and amd64 kernels but not bootloaders | 20:24 |
| === prpplague^2 is now known as prpplague | ||
| GrueMaster | You will have to google for it as we don't have any bootloaders that are known to work with Apple arm platforms. | 20:24 |
| gfunk | I am googling now... I see some have tried on the iPAD | 20:25 |
| gfunk | unsuccessfully....... | 20:30 |
| Jef91 | huh | 20:45 |
| Jef91 | even the Ubuntu netboot initrd doesn't boot properly in qemu | 20:45 |
| Jef91 | jburkholder1 got the netboot image rolling... | 20:51 |
| Jef91 | ooo spoke too soon | 20:54 |
| Jef91 | Image gets through the first few installer screens and then just died on me | 20:54 |
| Jef91 | just the blue ncurses screen with nothing up shortly after it starts downloading | 20:55 |
| jburkholder1 | oh, well you got your console working I guess, can't help much from here :) | 21:03 |
| Jef91 | :-/ | 21:05 |
| Jef91 | with the natty netboot image I am geting this in terminal when I try to star the QEMU "Unknown cp14 read op1:0 crn:0 crm:0 op2:0" | 21:08 |

| Jef91 | is there any way to run an arm machine on a desktop system other than qemu? | 23:07 |
| persia | Use an arm desktop :) More seriously, there are some commercial tools, but they aren't especially better, except for simulating specific hardware. | 23:23 |
| Jef91 | ahh persia | 23:37 |
| Jef91 | qemu keeps giving super mixed results | 23:37 |
| Jef91 | and I've yet to find any guide that works for getting ubuntu or debian ARM working under QEMU | 23:38 |
| persia | I've never had real success with it myself. Some sporadic success with jaunty, but most of the times I've tried it since have been frustrating. | 23:38 |
| persia | Hardware is becoming increasingly inexpensive and available. Some devices for as little as USD 99. | 23:39 |
| Jef91 | yea I know | 23:39 |
| Jef91 | I'd just really like a full system to type commands and such into | 23:39 |
| persia | If you just want to run commands, the cross-chroots with qemu-static work fairly well. | 23:41 |
| persia | Yes, this doesn't help with kernel testing, but can do most other things. | 23:42 |
| Jef91 | true | 23:42 |
| Jef91 | Whats a cross chroot again? | 23:42 |
| persia | Some dynamic allocators and anything that depends on binfmt tends to break, but that'S a minority of things. | 23:42 |
| persia | You build an armel chroot on a non-armel system. | 23:43 |
| Jef91 | Got a link for a HOWTO on that one? | 23:43 |
| persia | `apt-get install qemu-user-static; mkdir chroot; sudo qemu-debootstrap --arche=armel natty ./chroot; sudo chroot ./chroot /bin/bash` | 23:44 |
| persia | Err, add a "sudo" in the front :) | 23:45 |
| persia | Oh, and "arch=armel". | 23:45 |
| Jef91 | persia can't find qemu-user-static | 23:47 |
| Jef91 | on a lucid base | 23:47 |
| persia | In lucid, install qemu-kvm-extras-static | 23:47 |
| Jef91 | thanks | 23:48 |
| persia | I'd still recommend a natty chroot, or at least maverick. Lots of porting wasn't complete until maverick. | 23:49 |
| Jef91 | ahh | 23:50 |
| Jef91 | can I have this do a debian chroot? | 23:50 |
| persia | Sure. qemu-debootstrap doesn't have a manpage, but it's argument-compatible with debootstrap. Just read debootstrap(1) on making a Debian chroot. | 23:51 |
| persia | For Debian, I'd recommend at least squeeze. | 23:51 |
| Jef91 | haha easy peasy | 23:52 |
| Jef91 | just "squeeze" | 23:52 |
| Jef91 | thanks mate | 23:52 |
| Jef91 | hopefully this will work well | 23:52 |
| persia | I'm not convinced that lenny had as strong armel support. | 23:52 |
| === Jef91 is now known as Jef91|AFK | ||
| Jef91|AFK | using squeeze | 23:53 |
| persia | I run squeeze on one of my machines, and haven't encountered any significant issues. Mind you, I run that headless, so haven't played much with EFL, but the base is definitely there. | 23:53 |
