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.
