[U-Boot-Users] problem with cfi_flash.c & AT91RM9200DK

[Morten]

Correction, U-Boot seems to detect the chip correctly :)

Mixed up bits and bytes, and dident understand how the 16 x16 worket, sorry 
for this !

So it seams like erase and protect works like it should, but it stil doesent 
change anything in the flash if i modify or copy code to it !

Any idears ?

Best Regards

Morten
