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

Hello all, I'm working with u-boot for booting in nandflash with the evaluation board atmel at91sam9260ek. Nandflash reads ok, but performing and erase doesn`t work.
I get these messages trying to erase a block of the nand and writing the environment variables to nandflash.
Any help? I'm missing a configuration parameter in config or what may happens?

OK
