[U-Boot-Users] Dataflash and JFFS2

[Marco Cavallini]

Andre,
I read all the other thread under your message.
I didn't understand what are you trying to do.
If this can help, I can say I am successfully using Dataflash with a 
couple of different custom boards based on AT91RM9200 (DK like)
Please post your u-boot configuration, your memory specification, and 
what you want to do.
