[U-Boot-Users] U-boot on MBX860-002

[Herbert Thielen]

Hi,

I've got an older Motorola MBX board "MBX860-002" (assembly number
01-W3269F02C) which I'd like to use for U-Boot/Linux.

Building U-Boot with a powerpc-860-linux-gnu-gcc (3.3.2) was
successfully (except the examples directory).
Unfortunately, the MBX board gives only some crude characters via serial
console (9600 8n1) after booting u-boot from flash. At least there is
some reaction on characters sent via RS232.

Currently I've no BDM debugger available, so it's not to easy to debug
this ;-)

Was anybody out there successful in running U-Boot on a MBX board? Any
hint?

So far, I tried to adjust the clock speed from 50MHz to 40MHz in
include/configs/MBX.h (see below), but without success (nothing seems to
have changed).

Any ideas are welcome.

Regards
	Herbert.
