ok i can boot now! Thank you! I flashed from 0x0 to 0x7FFFF (image size: 479K). I flashed the environment image (image size: 3K) from 0x80000 to 0xFFFFF and changed the config code from barebox/environs/common/config to: ... nand_parts="512k(barebox)ro,768k(bareboxenv),4M(kernel),120M(root)" ... Barebox can boot now but the startup log says: barebox 2012.03.0-dirty (Jul 16 2012 - 09:01:01) Board: i.MX53 eth@eth0: got MAC address from EEPROM: ********************* nand_get_flash_type: second ID read did not match ef,ef against c0,c0 No NAND device found (-19)!
