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

Was anybody out there successful in running U-Boot on a MBX board? Any hint?
Obviously.
Hm, I was inaccurate, sorry. There are many versions and releases of MBX860 boards; to make my life easier, I was searching for somebody with exactly the same assembly number "01-W3269F02C" (i.e., the C stepping of this board version).
In between I've access to some later steppings (01-W3269F02E, 01-W3269F02G), where U-Boot is working (after changing CONFIG_8xx_GCLK_FREQ from 50MHz to 40MHz in MBX.h).
Any ideas are welcome.
You did read "doc/README.MBX", didn't you?
Yes, thanks for the hint. For the old C-stepping of the board I'll need CFG_USE_OSCCLK, as the customer letter mbxa_lt1.pdf tells that up to the C stepping, a 32.768 KHz crystal was used as frequency source for all MPC860 functions.
I made some trials even with fixed values for PLPCR and BRGC1, but up to now I wasn't lucky. Somewhat hard without BDM debugger.
As I've got a working board for the moment, I'll solve this problem later and tell the results.
Best regards
Herbert.
