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

Hi,
normally the chip vendors state the capacity in megabits, not megabytes, whereas U-Boot shows the capacity in megabytes. Your AT49BV320C holds 32 Mbit, which equals the 4MBytes shown by U-Boot.
Cheers Anders
Disclaimer: I didn't consult the data sheet of that particular chip.
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

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)
