But what I know: it trys to read the SD-Card, since there's a little bit of a different startup when booting without the Card. You try to boot up from SD card, why use at91sam9x5ek_nandflash_config? why not use at91sam9x5ek_mmc_config directly? Anyway, for NAND flash, please check the jumper setting, do you disable it? > Thank you! and greetings > > Frank Best Regards, Bo Shen
