Hi Ruiyu, 1. Your erase command is not correct. 2. You didn't enable MTD block device support in kernel config
JFFS2 needs the so-called "cleanmarkers" written to empty blocks. For NAND, these are special markers written in spare area. Instead of flash_eraseall, use flash_eraseall -j. And for /dev/mtdblockX, you need CONFIG_MTD_BLOCK turned on.
