Which Kernel for Ocotea (440GX)?

Which Kernel for Ocotea (440GX)?

[Wolfgang Wegner]

Hi List,

sorry for the blunt question...

I want to get an Ocotea dev board (AMCC 440GX) up and running.
As I saw from old posts (2004/2005) that this board should be supported,
I simply fetched a 2.6.24 kernel and - could not find a valid target...

It seems that support for 440gx in the arch/ppc tree was disabled, but
not yet ported to arch/powerpc.

As I am new to Linux/PowerPC, could anybody give me a hint either which
kernel version to use that supports 440GX/Ocotea out of the box or if
there is another repository of a more recent kernel where I could get
that?

Thank you very much!

Regards,
Wolfgang

You can find Ocotea support (still arch/ppc only) in our kenrel
repository - see git://www.denx.de/git/linux-2.6-denx.git

I think if you just followed the links on AMCC's web site they should
have taken you there, too. Please let me know if this didn't work for
some reason.

Best regards,

thank you very much, I fetched the kernel and at least it built
correctly.

It seems I am still doing something wrong with configuration, but as
I am getting this far, it should be possible to solve. I just wanted
to give feedback in time that the build is OK.

Thank you and best regards,
Wolfgang

At the moment this is what I get:

Re: Which Kernel for Ocotea (440GX)? - working now

Hi again,

sorry for the confusion, I forgot to activate the serial console support,
now the kernel is booting up fine until it tries to mount the root
fs.

Thanks again,
Wolfgang
