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 Victor Librado ha scritto: > > > > Hello all, > > I'm working with u-boot for booting in nandflash with the evaluation > > board atmel at91sam9260ek.
