[ts-7000] 7800 Root FS corruption

["robert2135" <>]

Hi all,

I've got a 7800 board setup to boot from the onboard NAND with the SD card 
mounted at /var. I've got scripts that run every so often to cleanup logs and 
other things so that the file system does not fill up.

I've had some 7800 boards in the field that seem to be getting corrupted NANDs. 
The boot script on the initrd runs, but it can't boot to the NAND.

I remember reading somewhere about an error in the partition table layout or 
something that caused the bad blocks table in the yaffs2 FS to be overwritten 
if the filesystem got close to capacity. Does anyone know anything about this?? 
I can't find the reference.

Has anybody successfully gone to a read-only-root FS? What issues did you have?

Thanks,
Robert
