However, if you use new bootstrap, it will show useful information as following: ---8>--- AT91Bootstrap 3.5.3 (Thu Apr 25 10:08:24 CST 2013) NAND: ONFI not supported NAND: Manufacturer ID: 0xec Chip ID: 0xda NAND: Disable On-Die ECC NAND: Press the recovery button (BP4) to recovery NAND: Using Software ECC NAND: Image: Copy 0x80000 bytes from 0x40000 to 0x21f00000 NAND: Done to load image ---<8--- > I really want to get a UBIFS root file system on this board. But, I haven't figured out how to do that yet, nor have I found a rootfs small enough to fit yet. For UBI file system support 1. if you want to mount, read or something else with u-boot, please reference to . Some quote information ---8>--- #define CONFIG_MTD_DEVICE #define CONFIG_CMD_MTDPARTS #define CONFIG_MTD_PARTITIONS #define CONFIG_RBTREE #define CONFIG_LZO #define CONFIG_CMD_UBI #define CONFIG_CMD_UBIFS #define CONFIG_SYS_MALLOC_LEN (4 * 1024 * 1024) // for mount ubifs ---<8--- 2. if you just want use ubifs as rootfs. just one thing for u-boot, it is bootcmd, please also reference .
