Hello all,
Can someone give hint where to start debug searching ??
I use distribution 20060511 2.16.16-uc0 on custom MCF 5208 board.
With flash, S29GL064AR4. Debug for mtd, jffs2 set to noisy.
When I mount a mtdblock on jffs2 I got the following error:
See below.
Command: mount -t jffs2 /dev/mtdblock3 /mnt
Command:
Command:
Execution Finished, Exiting
mtdblock: read on "Romfs" at 0x3d400, size 0x200
