| Gopal | can some one help me get ubuntu running on beagle baord | 19:20 |
|---|---|---|
| DanaG | http://elinux.org/BeagleBoardUbuntu -- that site is helpful. | 19:21 |
| Gopal | I have installed as per instruction and now at waiting for root filesystem | 19:21 |
| DanaG | I use kernels from "rcn-ee.net" | 19:21 |
| DanaG | there are some root images also. | 19:21 |
| Gopal | I have tried those images but stuck at Waiting for root device ... | 19:22 |
| Gopal | [ 23.791564] mmc0: new high speed SDHC card at address aaaa | 19:22 |
| Gopal | [ 23.797668] mmcblk0: mmc0:aaaa SD04G 3.69 GiB | 19:22 |
| Gopal | [ 23.802490] mmcblk0: p1 p2 | 19:22 |
| DanaG | hmm, try without the "boot.scr" file on the FAT partition. | 19:22 |
| DanaG | and what format is your second partition? if it's ext4, you'll need to tweak u-boot. | 19:23 |
| Gopal | no it is ext3 | 19:23 |
| Gopal | I will try removing boot.scr file and try | 19:23 |
| Gopal | Hello Dan, I have removed boot.scr file and still same situation | 19:29 |
| DanaG1 | hmm, what kernel, and what root? | 19:35 |
| DanaG1 | I found if I tried to use a karmic listed kernel with lucid rootfs, for example, it hung at about the same point. | 19:35 |
| DanaG1 | If you have serial console, it might be helpful to pastebin it. | 19:36 |
| KjetilK | Hi all! I just came across this: http://news.softpedia.com/news/Acer-Prepares-Freescale-i-MX515-Powered-Smart-Monitor-131435.shtml | 20:21 |
| KjetilK | and it occured to me that the monitor could be ideal for running a mythfrontend and X server only, assuming it has the power... | 20:21 |
| KjetilK | I don't know if mythtv-frontend is packaged for ARM, but would it be realistic to do something like that with Ubuntu? | 20:21 |
| persia | It's completely realistic. | 20:22 |
| KjetilK | sounds great! | 20:23 |
| KjetilK | so, this CPU will give sufficient performance for 720p with a mythfrontend? | 20:23 |
| persia | Well, depends on a whole number of factors :) | 20:24 |
| persia | You will want to have the right graphics drivers, or it won't be as useful as you'd like. | 20:24 |
| persia | Or just show simple video. | 20:24 |
| KjetilK | right | 20:24 |
| persia | I have a similar CPU in my NetWalker. For some sorts of video, it works great. For other sorts, it's slow. | 20:25 |
| KjetilK | oh, ok | 20:25 |
| persia | Looks like mythtv needs a bit of work to compile though : https://launchpad.net/ubuntu/+source/mythtv/0.23.0~trunk23623-0ubuntu1/+build/1534609/+files/buildlog_ubuntu-lucid-armel.mythtv_0.23.0~trunk23623-0ubuntu1_FAILEDTOBUILD.txt.gz is a log of the build failure from a couple weeks ago. | 20:25 |
| KjetilK | is it the encoding is the main factor? | 20:25 |
| persia | I don't really know. | 20:26 |
| * persia doesn't tend to watch much video on that device. | 20:26 | |
| KjetilK | OK | 20:27 |
| persia | KjetilK: Any help getting the mythtv stuff ported/working would be much appreciated. | 20:28 |
| KjetilK | yup, I know :-) | 20:28 |
| KjetilK | I would need to buy the device first, then :-) | 20:28 |
| KjetilK | I haven't got any ARM devices now | 20:29 |
| persia | We have an emulated compilation environment available, if you have an Ubuntu lucid i386 or amd64 install. | 20:29 |
| KjetilK | Yeah, I was hoping to get a lucid system running RSN, but real life has interferred too many times :-/ | 20:29 |
| KjetilK | also, the real reason why I started to look into this was not myth, but something else | 20:30 |
| persia | Well, when you get one, ask here, and I'm sure someone can explain how to set up the emulated environment (it's just `mk-sbuild --arch=armel lucid` but that's easy to forget) | 20:30 |
| KjetilK | I was looking for a cheap device that could transcode and stream video real-time from commodity video cameras over wifi :-) | 20:31 |
| persia | Also, if you want to look at mythtv on armel, JamieBennett is probably the person regularly in this channel with the most interest in that area (but perhaps little time). | 20:31 |
| KjetilK | yup, great! | 20:31 |
| persia | Same issues really : transcoding. A lot depends on having drivers that can *use* the DSP. | 20:31 |
| KjetilK | right | 20:32 |
| KjetilK | could the TI OMAP3525 be a candidate for something like that, or would one need something more powerful? | 20:34 |
| KjetilK | I kinda like the Gumstix way of doing things :-) | 20:34 |
| persia | Personally, I think all the chips are roughly similar in power, but a lot depends on the drivers. | 20:36 |
| KjetilK | ok | 20:36 |
| persia | Hunt around and find out which chip seems to have the best open DSP drivers for linux. | 20:36 |
| persia | Otherwise you'll be doing it on the CPU, and none of them will perform wonderfully under those conditions. | 20:37 |
| persia | (not that the CPUs are slow, just that they aren't as fast as GPU or DSP processing). | 20:37 |
| KjetilK | yeah, this clearly requires some work | 20:40 |
| KjetilK | Also, I suppose another matter could be if Acer has decided to try to prevent people from replacing the OS of that device | 20:41 |
| KjetilK | well, for all I know, it could be Ubuntu running on it already | 20:41 |
| persia | Oh, right :) But most devices get hacked eventually. It's just a matter of tracking which devices have a way to install them. | 20:44 |
| DanaG1 | oh yeah, you may not actually need a usb-hub power adapter if you have a power adapter for the beagleboard itself. | 20:55 |
| KjetilK | yup :-) | 20:55 |
