Linux on Motorola Sandpoint/PPMC7400

Hi,

I've seen that Hard Hat Linux supports the Sandpoint board with
MPC8240 and MPC755. We have a 7400 processor there though. Does anyone
have any experience with this configuration? Can Linux run on it?

Also, is there anything special I should know about booting Linux from
dink32? Here's what I did, and how it failed. I got the latest kernel
snapshot from fsmlabs (I tried the same with both the latest 2.2 and
2.3 trees). I set in the Makefile ARCH := ppc and CROSS_COMPILE :=
powerpc-linux- (the prefix for the tools that I have installed, on my
Debian box, from www.emdebian.org). "make menuconfig", there I made
sure I have support for serial console, there I also set the boot
command line (PReP command line it says) to "console=ttyS0,9600
console=ttyS0 root=/dev/ram" (I don't really have initrd yet, I want
to see the kernel booting first). Then make zImage, which compiles
fine, "file arch/ppc/boot/zvmlinux" tells me it's indeed a PowerPC ELF
image, then I zsrec it to an srec file (I tried all kinds of offsets
-- does it matter?), then I upload it to the PowerPC box, then I "go"
to that offset, and then it just hangs...

Any ideas what to try? I'm simply lost...

Thanks a lot in advance!
