Yesterday, I can use "cp jffs2.img /dev/mtd0" to copy the jffs2 image
to mtd. Today, I applied the cvs snapshot of mtd to kernel and
compiled it. Suddenly, the "cp" command stops working.
it tells me:
MTD do_write_buffer(): software timeout
cp: writing '/dev/mtd0' : Input/output error
any idea?
thanks

Did you erase the chip before writing to it like that again? If not,
you'll need to do:
flash_eraseall /dev/mtd0
Then try your copy again.

I did it every time before I want to write to it :)
It just works yesterday. Today I applied the patch and recompiled the
kernel 2.6.12.
It stops working :(
