Latest mkfs.jffs2 is broken.

[H Hartley Sweeten]

Hello all,

Buildroot recently bumped the mtd-utils package from version 1.3.1 to 1.4.0.

With the mkfs.jffs2 utility in 1.3.1 I am able to create rootfs.jffs images that
work fine on my i.mx35 arm system.  But, with the 1.4.0 version all the images
do not work.

With the 1.4.0 built images I get messages like this during the kernel boot:

jffs2_scan_eraseblock(): Node at 0x00000000 {0x1985, 0x2003, 0x0000000c) has invalid CRC 0x813c6fd8 (calculated 0xe41eb0b1)

Old JFFS2 bitmask found at 0x00000078
You cannot use older JFFS2 filesystems with newer kernels
Empty flash at 0x0000a46c ends at 0x0000a470

And, if I check the images with jffs2dump I get stuff like:

Wrong hdr_crc  at  0x0001f808, 0x783f44d2 instead of 0x1d1d9bbb
Wrong bitmask  at  0x0001f80c, 0x07f3
Empty space found from 0x0001fffc to 0x00020000

Any ideas what could be wrong with the 1.4.0 release?

Thanks,
Hartley
