problem in accessing rfs from /dev/mtdblock4

parthahazra — Tue, 11 Dec 2012 15:54:19 GMT

I am trying to mount my file system jffs2 from Nor flash (WEIM Bus) in linux 3.7-rc4.

I am able to access NOR flash from uboot and write the images at partitions mentioned in below log.

Following command is used to build a jffs2 image.

mkfs.jffs2 -e 128 -l -n -r rootfs -v -o test.jffs2

File system fails to boot after kernel has come up.

Please refer to the below error log.

Please suggest.
