Hello everyone!
Trying to boot linux 2.6.12 on an MPC8245 board from MEN (a12) with MenMo=
n =20
firmware. Nothing is printed to the console (ttyS0), but the __log_buf =20
contains this:

adding 'nobats' to the command line changes the boot output slightly (I =20
then get two oops).
In order to get the whole output I had to turn off caching, maybe this ha=

influenced the boot process.. with dcache on, the __log_buf is practicall=
y =20
empty.
Has anyone managed to boot 6.12 on this board successfully?
Thanks in advance,
Carl.

This looks like an issue with the MEN port. without that code its
difficult to comment on what exactly may be wrong.

Seems sth wrong on target init configuration. Pls
check some values like MPC10X_MAPB_EUMB_BASE or
UART related stuff like SERIAL_PORT_DFNS. Well, I
just have the successful experience on a MPC8241
target based on SANDPOINT board with 2.6.12-rc2 and
2.6.13-rc3.
In addition, enable early console is also a help to
debug.
Best regards,
Sam
