jffs2_scan_eraseblock Magic bitmask not found error

Mon Mar 5 07:28:22 EST 2007

Hi,

 I am not able to mount my JFFS2 file system. I am getting "Magic bitmask
not found" errors.

I am able to successful detect the flash chip as:

phys_mapped_flash: Found 1 x16 devices at 0x0 in 16-bit bank

 Amd/Fujitsu Extended Query Table at 0x0040

 My JFFS2 FS image is of the same size as the MTD partitions (padded till
the full size)

   - I could see that both *flash_eraseall –j *and the *mkfs.jffs2* keep
   clean markers at same location but the jffs2_scan_eraseblock API looks for
   the magic bitmask (0x1985) at a different location, resulting in that errors
   shown below.

jffs2_scan_eraseblock(): Node at 0x00000000 {0x1985, 0x000c, 0xb0b1000c) has
inv

alid CRC 0xffffb0b1 (calculated 0x23f72e11)

jffs2_scan_eraseblock(): Magic bitmask 0x1985 not found at 0x00000004:
0x000c in

stead

If I try to mount a clean partition (not even with clean markers), mount
will be successful just once. And creates the clean markers just similar to
flash_eraseall –j. If I umount and mount it again, I get that bitmask
errors.

I used the default map driver (simple_map_read, simple_map_write apis) as
well as my own map driver that differs from the default one by changing the
flash chip's mode to program mode in write explicitly. Both gave me same
results.
