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.
Hi Herbert, yes this has been done before. Check the archives for both this list and the archives for U-Boot's predecessor, ppcboot. Or just google for mbx860 and ppcboot and you will find it.
