LinuxPPC on a Motorola MVME2400

LinuxPPC on a Motorola MVME2400

[Simone Piccardi]

Hi,
we buy just some day ago a Motorola MVME 2431 VME board, to use it for
data acquisition for a Cosmic Ray Physics experiment. I saw from
previous mail that someone has started LinuxPPC on this board. 
Could you give us some info about it? 
Because I'm new to this board and to LinuxPPC (I always used linux on a
PC machine), there is some place (or any kind of documentation)
describing the boot procedure (we would like to use the net booting by
tftp)? 
Thank you in advance

I have Linux/PPCeeee running quite well on 2600s. The corresponding
patches are at:

	ftp://vcorr1.iram.es/pub/linux-2.2/

in files mvme2600.generic-patch-2.2.4 and mvme2600.vme-patch-2.2.4.
(this last one is a VME driver subsystem which I hope to officialy
announce soon, if I can find time to do something else than answering
e-mail).

I've not yet upgraded the various zImage (next week). They have serial
consoles and I've used root-on-NFS with 2.2.1. 

However, the 2400 has a new chipset (Hawk) which is not yet recognized.
If you have the technical information about it, it will be fairly easy to
add support in the early boot code. 

	Regards,
	Gabriel.

Programming is the same as Falcon/Raven since it just integrates them.
The only thing that is needed is perhaps to detect it in your OpenPIC
code.  We are using a different OpenPIC patch as well as some stuff to
detect all the MCG boards and set interrupt routing properly.  Hopefully
it can get rolled in soon.

This really sucks that some of us are working from official tarballs and
some are working from vger. :-/  Though I do understand your bandwidth
constraints to the U.S.

Ok, thanks. It seems the BW situation is improving. But I'll wait until
the release of the VME driver before going back to vger. I've been bitten
very hard in January when vger was closed and had to go back to
official tree. Is there such a big diff between vger and Linus since 2.2.4
(which was painful enough to apply on my tree) ? 


BTW: which bootloader do you use ? I'm going to make significant changes
to prepboot soon (switching to a CHRP like map when a Raven/Falcon/Hawk
is found) ?

	Regards,
	Gabriel.

I posted a patch (check the archives) for DEC21x4x driver a while back.
You'll need that on the 2400.  I don't know if it's in Gabriel's patches
especially since he doesn't need it on his 2600.

The 2.2.5 vger stuff should work well with this board and the de4x5.c
patch, though it won't have OpenPIC support and you may need to modify
interrupt routing for PMC slots if necessary.  I use a local repository
with all this stuff that is has not yet been rolled in and I haven't had a
chance to sort out some patches.

Hi,
thanks for the info. I was trying to build the cross-compiler (so still
I do not even try to boot the system). I look at your page, but I find a
broken link for binutils. 
I have also another question, I'm using RedHat 5.2 that has egcs 1.0.3
(but not for gcc, must I switch to Debian?). 
I find some rpm for egcs 1.1.2, but in the page you are using 1.1.1,
must I find this release ? 
Thank you in advance.
Bye

 Hmm, it seems the maintainer of the Pre-R5 archive is updating his
 site. I don't know how long it will take for the site to get back.
 I do know that a Redhat 4 will cause problems. It did with my board and
 with other folks' boards too. If you can find a more recent Redhat for
 PPC, it might be better. But I cannot say for sure.

 A more recent egcs can only be better ! Honestly, I don't know if it
 will cause troubles, but I think it's OK. The gcc on my MVME board is
 egcs and gcc version 2.9.1.

I fixed the build instructions on my page for binutils and egcs, but have
not tested or updated the binary packages to match yet.  glibc
instructions are not updated at this time because alpha.gnu.org is down
and I can't verify the latested glibc version.

My page was just outdated.  I've been using the older versions since I'm
just working kernel issues and it is has been faster to build kernels on
an available PII/400.  rpms for egcs you're finding are most likely native
compilers.  There is no need to switch dists.  Also, I will update my
binary packages soon and the Debian should be available on the next
official Debian release.
