生成rootfs.jffs2

mkfs.jffs2 -r nfsdir -o rootfs.jffs2 -e 0x80000 -n

-e 擦除块大小512k

-n 去掉生成映像中的clean marker

UBIFS

运行的时候出错

UBIFS error (pid 1): validate_sb: LEB size mismatch: 520192 in superblock, 516096 real

/article/7851767.html

说明是在制作ubifs文件系统时出错

在PC上制作buifs

mkfs.ubifs -r nfsdir -m 4096 -e 516096 -c 2024 -o ubifs.img

ubinize -o ubi.img -m 4096 -p 512KiB ubifs.conf

cat ubifs.conf

[ubifs]

mode=ubi

image=ubifs.img

vol_id=0

vol_size=615MiB

vol_type=dynamic

vol_name=rootfs

vol_flags=autoresize

参数说明：-m 页面大小4K 4096 –e逻辑擦除大小可以通过ubiattach /dev/ubi_ctl –m 2查看

-p 物理擦除块大小 512Kib

在nfsdir下运行

首先删除/dev/ubi0(上一次创建的)

rm –rf /dev/ubi0

格式化/dev/mtd2

ubiformat /dev/mtd2 -f ubi.img

探测关联

ubiattach /dev/ubi_ctrl -m 2

mdev –s

通过ubinfo –a查看如果有ubi0上的标志就可以测试了

如果没有则创建

ubimkvol /dev/ubi0 -N rootfs -s 800MiB

测试：mount –t ubifs ubi0:rootfs /mnt

设置环境变量：

setenv bootargs root=ubi0:rootfs ubi.mtd=2 rootfstype=ubifs console=ttySAC0,115200 init=/init
