Hi,
I am trying to mount a JFFS Filesystem from Flash as a root Device. I faced
the following Problem . Required help on this regard
*****************
NET4: Unix domain sockets 1.0/SMP for Linux NET4.0.
cramfs: wrong magic
attempt to access beyond end of device
1f:00: rw=0, want=65, limit=64
isofs_read_super: bread failed, dev=1f:00, iso_blknum=32, block=64
JFFS: Trying to mount device 1f:00.
