你好我使用target # flash_eraseall /dev/mtd4
target # mkdir -p /mnt/nand
target # mount /dev/mtdblock4 /mnt/nand -t jffs2
target # cd /mnt/nand
target # tar zxf /home/root/filesystem.tar.gz
target # sync
target # cd /home/root
target # umount /mnt/nand
说明烧录文件系统
发现
root@dm368-evm:~# flash_eraseall /dev/mtd4
Floating point exception
root@dm368-evm:~#
是不对的
cat /proc/mtd
root@dm368-evm:~# cat /proc/mtd
dev: size erasesize name
mtd0: 003c0000 00020000 "bootloader"
mtd1: 00040000 00020000 "params"
mtd2: 00400000 00020000 "kernel"
mtd3: 0f800000 00020000 "filesystem1"
mtd4: 00000000 00000000 "filesystem2"
于是我就
flash_eraseall /dev/mtd3
结果nand全部格式出错 需要从新格式化 烧UBL
