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
......
Your root filesystem isn't also on the same flash
as the JFFS2 you are trying to mount is it?
If you where running apps XIP then this would be a problem.
Regards
Greg
