Are you sure that the flashes ever worked?  One  typical  problem  is
that  it  seems quite natural to connect the D0 pin of the flash chip
to the D0 pin of the data bus, etc. - which is wrong, since  for  the
flash chip D0 is the LSB, but on PowerPC bit 0 is the MSB...

Can you access (read, erase,  program)  the  flashes  through  a  BDM
debugger?

Best regards,
