Hello,

I'm trying to get a Linux distro such as Debian in the following system

System:
mpc8572ds HW
u-boot programmed on flash memory
vanillia linux installed on sata disk

Restrictions:
i have not apt-get resident on system


I have tried the following ways with no succeful results:

I tried to run deboostrap with chroot on mpc8572ds

I tried to run deboostrap on another machine, downloading the correct
packages for ppc enviroment and copiny those packages in a new ext2
partition of my 8572 hw. After that i executed "chroot /mnt/newpartition
/bin/bash" and it returned "Illegal instruction". At this point i can't
follow the installation and if i force to startup the machine with that rf
system, it returns a "kernel panic" with error to handling the signal 4 of
init process.

I tried to get start the machine with a debain livecd installation. I
created an uImage and initrd from cdrom's vmlinux and initrd.gz with the
uboot-mkimage tool, then i booted it from u-boot but the kernel didn't
start.

I tried to start a preinstalled Debian for a simillar architecture, in
cocnret from a mpc8561 ppc's Debian. I put its hhdd with the Debian rfs on
my machine and start it with my uImage and dtb files. The results was the
same "kernel panic" and signal 4 error.



I accept all ideas.

Thanks you all and sorry for my english

The 8572 does not have classic PowerPC floating point.  The Debian
binaries use this, so they cannot run without emulation.

Emulation is slow, so you probably want something like this instead:

Do you have floating point emulation turned on in the kernel?

Hello,

I'll try the "linutronix-lenny-gnuspe/" distro option, because i prefer a
option without a fp emulation.

Thanks u all.
