Hi guys,
I do not have the original message so pardon me for responding to this
one.
I had a similar problem at this location:
1. There were different versions of where the uncompressed kernel is
started from.
Once it was done directly from address 0 and the other time the content
of
location 0 was used. Make sure the arch/ppc/kernel and arch/ppc/mbxboot
directories
match regarding this point.
2. Make sure that the DER reg is set to 0 when using an emulator.
Especially
an ADI board for the FADS. For example "rms der 0".
I hope this helps,
Nicolas
