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

Tue Oct 5 19:55:12 CEST 2004

Have re checked all Hardware, and every thig seems to be correct, but i stil 
have the same problem.
all commands seems to be working (no errors) but nothing gets writen to the 
AT49BV320C !

One thing i have noticed is that in debug mode, when i try to write to the 
flash, it keeps saying bussy all the time,
could the Atmel flash be using a slightly different Command set than the 
ones inplemented in the cfi_flash.c ?

please, if anyone has any tips, i would be very greatful :) going out of my 
mind her ..
4 prototype boards behaving juste the same ! (based on the AT91Rm9200DK ref 
design)

Best Regards

Morten
