Thanks for your answer, I successfully built the OpenFirmware's ROM by trying older subversion's revisions (thanks to Marcin). Now that I have the ROM, I am stuck on loading the ROM using Qemu.

Hello Marcin,

Thanks again for your help, it solved the issue in a way. Tried several older revisions: r3500, r3000, r2500, and finally r2000. Only the revision 2000 successfully built the ARM rom called ofw.rom. This revision is from 2010-10-08 02:39:55, when the documentation is from 2010-08-11, 18:45.

Here’s the output :

Only the following line still warns us of a potential issue : ${BP}/ofw/gui/iconmenu.fth:183: expand-rect ?
It seems to concern an icon, so it should not be a problem; the ROM is built, and this is what I wanted.

As it is explained in the documentation, the last step should be to launch qemu : qemu  -L . -bios ofw.rom  -hda fat:.
Here’s the output :

jacky@debiannos:~$ qemu-system-arm  -L . -bios ofw.rom  -hda fat:.

No machine specified, and there is no default.

Use -machine help to list supported machines!

jacky@debiannos:~$

Let’s specify the machine :

jacky@debiannos:~$ qemu-system-arm  -L . -bios ofw.rom  -hda fat:. –machine none

This time, a Qemu window pops, with the following text:

compat_monitor0 console

QEMU 2.1.2 monitor – type ‘help’ for more information

(qemu) $

 

That’s just the Qemu console, correct me if i’m wrong, the bios is not executed.

So I tried some other machines:

jacky@debiannos:~$ qemu-system-arm -L . -bios ~/openfirmware-r2000/cpu/arm/mmp2/build/ofw.rom –cpu cortex-m3 -machine lm3s811evb -hda fat:.

vvfat . chs 1024,16,63

Guest image must be specified (using -kernel)

 

And:

jacky@debiannos:~$ qemu-system-arm -L . -bios ~/openfirmware-r2000/cpu/arm/mmp2/build/ofw.rom -machine connex -hda fat:.

vvfat . chs 1024,16,63

A flash image must be given with the 'pflash' parameter

jacky@debiannos:~$

Also tried with almost all the ones listed thanks to the command qemu-system-arm –machine help.
Why would a flash or a kernel be required when it was not, using Qemu for x86 ?

Which kernel and flash should I use in order to run OpenFirmware? I suppose this question is partly getting off topic, as the base issue has been solved, maybe you want me to open another topic ?

Again, thanks a lot.
