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

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?

No, this sounds like a driver problem. Do you use the old legancy NAND interface (CFG_NAND_LEGACY) with the old access macros (NAND_DISABLE_CE...), or do you use the new interface?

Best regards,
Stefan
