[U-Boot-Users] u-boot on nadflash for at91sam9260ek

I am using the same value for the SMC registers as stated in my linux
kernel board-at91sam9260ek.c. In linux I can perform nandflash
read/erase/write ok. (flash_eraseall / nandwrite commands).

May I have to define the JFFS2 partitions in u-boot configuration
my_board.h as I have in Linux?

Commands: *CONFIG_JFFS2_NAND_OFF*, CONFIG_JFFS2_NAND_SIZE ...?

Regards,
V?ctor

Victor,
you should check registers settings and timing into yourboard.h
configuration file

Ciao
