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

Hello !
I have exchanged the flash on my AT91RM9200DK with a AT49BV320C cfi flash, and done all needed mods to the config file, every thing seems ok except that it get the size of the flash incorectly.
It sayes that it is a 16x16 4m, 71 sector cfi complient flash, when it should be a 2097 x 16, 32m, 71 sector flash ?
Anyone have any tips for me on how to fix this ? protect / unprotect seems to work fine, and it even writes without complaining, but nothing actualy gets writen !
