On my ixp1200 system (sa1100 + ...), I am now
running linux-2.3.99-pre3 with the patches
2.3.99-pre3-rmk3 and pre3-rmk3-np2.
It does fine until the /sbin/init is run. I am using the
ramdisk from nico's site. I get a number of
pc: undefined instruction always at the addresses
0x4004be04 and 0x400105b4. I tried replacing the
/sbin/init with just bash. I see the bash prompt,
but get the same undefined instructions at the same
addresses. I wrote a small infinite loop hello world
program, and that seems to work fine.
Any ideas on how to debug this ?? It looks like the
page table for the process is messed up.
I have tried to keep my ixp1200 port very very close
to the SA1100 port. One thing I did have to do was to
replace the serial driver with a serial driver modified
from 21285 which seemed a lot cleaner. Otherwise, I
would get to the /sbin/init and just hang.
Thanks
uday
