Hello,

I have developed a script to create a Linux Ubuntu/Debian distro for your roboard from an existing Ubuntu/Debian install.

Use it as mentionned in my wiki to build a working minimal ubuntu for your RB-XXX :

Code: Select all
sudo ./make_distro.sh -a install -p ubuntu-standard,linux-generic -o linux-image-2.6.34.10-vortex86-sg_1.2_i386.deb -b /dev/mmcblk0


As you can see I use the kernel provided by Roboard and the generic one from ubuntu. That's because I have a kernel panic problem with the Roboard one. I'm working on it.
But the generic kernel from ubuntu works perfectly.

When Roboard kernel panic will be solved, it should be possible to build a 12.04 ubuntu distro for your roboard with the same process.

Feel free to report bugs, new features, usage problems, etc...

Enjoy and share !

Hi,

is the 12.04 stock kernel working for you? I myself cannot even start the installer. I tried installing 12.04 on the flash drive in virtual box, but the roboard seems to crash immediately when I try to boot from that flash drive...

Cheers,
Niko

Hi demmeln,

My method is completly different than the classic one using an installer.

Based on debootstrap, I build my system from command line.

So yes I can build the base for a 12.04 distro. But I cannot boot it for now because I do not have a working kernel. It is coming soon :)

Hi gdo and demmeln,

Processors(include Vortex86DX) without cmov instruction are no longer supported by Ubuntu team. All packages are built for i686 platform.
So, we think Ubuntu 10.04 is the latest version that could run on our roboard.

We suggest that you could try using Debian to replace Ubuntu.
Until now, Debian still supports i486(i586) platform.

Hi roboard,

thanks for the the heads up. I think we'll stick with lucid then. Good thing ros fuerte is supported on lucid.

+1 :D

But it is just the kernel provided that does not support processors older than i686. Using the DMP kernel it should work. (with no support and maybe with some bugs but it should work for a minimal ubuntu install).

I will try it and tell you the result once I have a working kernel rebuilt. ;)

By default my script build a lucid distro so you can try it.

Hm... I'm don't know so much, but woulnd't the i686 instruction problem also apply to all library / executable binaries outside the kernel?

I have a working lucid installation (via virtualbox) already, but I have to try you script just for the sake of it! :)

And yes please, keep us updated! Thanks!

Hello.

I'm trying to boot the RB-110 with Ubuntu 12.04 using this method and I'm having the "Kernel Panic" problem.

There is any solution now?

Thanks in advance.

Hello mbj,

Could you give me the exact command you have used and the kernel panic trace ?

Kernel Panic coud have various reason.

Hello gdo, thanks for your fast answer.

Firstly, I downloaded your make_distro code and executed it with the next command:

Code: Select all
sudo ./make_distro.sh -a install -p ubuntu-standard,linux-generic -o distros/linux-image-2.6.34.10-vortex86-sg_1.2_i386.deb -b /dev/sdb


I tried with "DEBIAN_VERSION=precise" (12.04) and this is the trace:

i49 [dot] tinypic [dot] com [slash] rtonet.jpg
(Sorry I can't put url's yet)

I tried with the "DEBIAN_VERSION=lucid" and "works" (well, I get a terminal line where I can login if I execute the non-Vortex86 kernel, but I can't start the X server, that's normal?). In case that I execute the Vortex86 modified kernel, I get the next ouput:

Kernel panic - not syncing: VFS: Unable to mount root fs on unkown-block(0,0).

After that, I tried changing the destination source to /dev/sdb1, but fails when it's making the distro in the step "Prepare rw image".

Can you help me? Thank you very much.

Ok I wait you could upload the trace.

Yes it is normal since you did not specified any desktop or X package in the command line. If you try this command line, you will get a graphic session :
sudo ./make_distro.sh -a install -p ubuntu-standard,linux-generic,lubuntu-desktop -o distros/linux-image-2.6.34.10-vortex86-sg_1.2_i386.deb -b /dev/sdb


In case that I execute the Vortex86 modified kernel, I get the next ouput:

Kernel panic - not syncing: VFS: Unable to mount root fs on unkown-block(0,0).


Do you mean that you used the generic ubuntu kernel with lucid with success but that it fails with the vortex kernel ?

After that, I tried changing the destination source to /dev/sdb1, but fails when it's making the distro in the step "Prepare rw image".

That's normal since sdb1 is a partition and sdb is the full disk containing partition. You must provide path to the full disk so /dev/sdb to the script

Can you help me? Thank you very much.


Sure I can. ;) I will launch some tests tonight to reproduce.

Sorry but I don't know how to capture the trace, is for this reason that I uploaded the photo. I googled the topic and I found that the log should be at /var/log/ folder, but after search through I haven't saw any kernel panic trace or similar. :(

Can you point me out how can I correctly get the trace?

Yes, I want to say that.

Ok, sorry, it was a stupid test... xD

Thank you again.

You cannot find kernel panic traces with /var/log. But just take a photo of your screen.
Or write the error associated with the kernel panic.
There is some ways to debug kernel and get traces but it is a bit "difficult" to use and not really needed for now.

Do you have the same one ?

Hi,

Then I have investigated this week end to know why you got this kernel panic.

I knew that the Ubuntu linux kernel was not supporting i586 arch any more since oneiric (11.10). But I was thinking that it was just the kernel. But it is wrong. The last available ubuntu distribution for roboard and generally for i586 is 10.04.

It is clearly writted on the ubuntu website :
However, Ubuntu oneiric will not run on i586 or earlier processors. Despite the architecture name "i386", support for actual 80386 processors (and their clones) was dropped with the Sarge (r3.1) release of Debian[2]. (No version of Linux has ever supported the 286 or earlier chips in the series.) Support for i586 and lower processors, as well as for i686 processors without the cmov instruction, was dropped in Ubuntu 10.10. Most i686 and later processors are still supported


The script is doing all fine. But it could not run any code from ubuntu since it is not build for i586 and lower, including in initrd and /sbin/init process.
