mount jffs2

今天测了一下自已生成的jffs2的image,跑不起来,出现:

INCA-IP-ROM # cp.b 80400000 b0040000 3b225c
Copy to Flash... done
INCA-IP-ROM # run flash_all
### JFFS2 loading '/boot/uImage' to 0x80400000
Scanning JFFS2 FS:  done.
find_inode failed for name=boot
load: Failed to find inode
### JFFS2 LOAD ERROR<0> for /boot/uImage!
## Booting image at 80400000 ...
Bad Magic Number

怀疑有可能是image做得有问题,所以打算把jffs2的image给mount进来看一看.

google了一下,原来弄这个还挺麻烦.

mount jffs2.img在loopback上
請載入以下modules
modprobe mtdcore
modprobe jffs2
modprobe mtdram
modprobe mtdchar
modprobe mtdblock
確認以上modules會產生/dev/mtd0 及/mtd/mtdblock0檔案
dd if=/jffs2.img of=/dev/mtd0
mount /dev/mtdblock0 /mnt -t jffs2
