ELDK on a PowerPC host machine?

ELDK on a PowerPC host machine?

[annamaya]

I noticed that ELDK from denx does not support running
on a PowerPC host machine like the Power G4 or G5.
When I tried rebuilding it on a Power G4 with
YellowDog installed on it, it complained that the
PowerPC host machine is not supported. Why is this
host architecture not supported? I also found out that
MontaVista does not support the PowerPC host
architecture anymore which they did a while ago. What
seems to be the real reason for not supporting this?
Thanks for the reply.

I'm guessing in the MV case it was cost vs demand.

Correct. PPC host are not supported yet. Also please  not  that  only
RedHat-7.3 will work as a build host without additional tweaking.

Little demand? We have seen less than 5 requests for this so far.

Probably the same reason: little demand.


Well: the ELDK is free software -  if  you  fix  the  existing  build
problems  and  send  me  a  patch I promise to check it in on the CVS
server (as long as it doesn't break anything). But don't expect  this
to be an easy job.

Thanks for the reply Wolfgang. Can you give me a hint
on the kind of work that is required to make this work
for the PPC host?

Hello, Annamaya

I am using a PPC Linux host here, too.

> Thanks for the reply Wolfgang. Can you give me a hint

> for the PPC host?

Maybe you can save a lot of work using a mainstream Linux
distribution for PPC and install the gcc/gdb development as
you need it?!
If you need the ELDK root tree for booting from nfs
just copy the ppc_zyxx- folder over from the ELDK.

Just today, I needed to move to ppc without the ELDK as we
ran out of fast ix86 machines for compiling. I had to go
'back' to my PowerMac G4 which was my 'functional prototype'
for Linux driver development.
Right now (today) I didn't miss anything from the ELDK.

I use the 'CRUX PPC' distribution on that ppc-machine which
is really nice to use (no bells, no whistles).
If you want a fully fledged KDE/Gnome X, maybe you check out
the 'CRUX PPC Evolution' port.
The most painful part was to have the Mac Bootloader installed
to keep have 1x Linux, 2x MacOSX and 1x MacOS9 bootable on
that machine. :-) Maybe I should use U-Boot next time ;-)

Best greets,

Clemens Koller

I do all of my development on PowerPC hosts because
I don't have anything else.  I regularly build compiler
tools to work in a "cross" environment, mainly to ensure
consistency of target binaries and libraries.  I'd be happy
to work with anyone that wants to rebuild ELDK for
YDL 3.x hosts.

If someone wants to use MVL 3.1 in such an environment,
we can discuss that, too.

Of course, if you have a PowerPC host, you can just cheat
in most cases and use the host tools.  This won't work for
such things and 8xx or 85xx SPE, but it would get you
started.

Thanks for the reply Dan. I may know someone who is
interested in porting ELDK for the PowerPC hosts. I'll
ask him to get in touch with  you soon.

Thank you for your input. I guess I need to be more
specific about my needs. I am looking to cross-compile
for my 8xx and 82xx based boards using ELDK on PowerPC
host machines.

What about the 8xx tools in ppc_8xx/usr/bin?  Won't they
run on a 'big' PowerPC as well?

Good idea. I'll give it a try.

RE: ELDK on a PowerPC host machine?

[Demke Torsten-atd012]

Hi,

we use the ELDK on G4 here in the following way:
a) install ELDK on x86
b) move target directory (the one you would use for NFS) to your G4
c) chroot into that target directory on yout G4
d) manually mount /proc, setup path, ...

Compilation of u-boot and Linux Kernel works fine. 
(tested with 82xx and 8xx).

Regards,
Torsten

Thanks for the reply Demke. This is exactly how I
managed to get it going on my G4 even before I read
