That's what I tried too. Here is what I get when I use the sst flash's (all
debug info turned on):

>>>
physmap flash device: 200000 at ffc00000
CFI: Found no Physically mapped flash device at location zero
<<<

On the amd flash board I get the following debug messages:

>>>

Any thoughts/suggestions?

Thanks a lot,
Stefan.
