You have added the generic flash layer, but there is no hardware
specific flash driver for the SNDS. 

Does the SNDS have flash? If so, it looks like you need to write a
driver for it. If its a well known flash chip, that should be
reasonably easy.

Which FLASH do you use in the snds board? I could send you a package
for two Atmel AT29C040A used parallel, but I don't know which flashes
are inserted after shipping.
