ti的专家们好，dm368用sd卡烧写成功后用nandflash启动系统，第一次启动系统正常，但是重启后系统就报错：
[ 1.408836] UBI error: ubi_io_read: error -74 (ECC error) while reading 126976 bytes from PEB 3:4096, read 126976 bytes
[ 1.446611] UBI error: ubi_io_read: error -74 (ECC error) while reading 126976 bytes from PEB 4:4096, read 126976 bytes
[ 1.460594] UBI error: ubi_io_read: error -74 (ECC error) while reading 11 bytes from PEB 9:6144, read 11 bytes
[ 1.491225] Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)
然后再也起不来了，请问这是什么问题啊？
