It's running a cut down version of the oiginal rootfs that comes with the board
and ts7400_tskernel-jul162008.tar.gz to get proper support for YAFFS2.
I've been running tmpfs right from the beginning so it hasn't been thrashed.
I have another unit that has been running the same software for a week and it's
got this in the log which is a bit worrying. I get the same bad blocks
mentioned each time I boot the board. Does this mean that there are only 3 bad
blocks (312,878 and 110)? Why is block 110 be retired 50 times at each boot?
yaffs: dev is 7937 name is "1f:01"
yaffs: Attempting MTD mount on 31.1, "1f:01"
block 312 is bad
block 878 is bad
