Hi,
I have been using a particular TS-7260 (NAND-2k) successfully for a few months but now the NAND appears to be faulty. I have been careful in my design to limit writes to the internal flash and use tmpfs and an external USB flash drive for files that are written often.
Could this be a hardware fault? What can I try to find out more?
df shows the yaffs partition is only 21% full
# echo hello > /hello
-sh: cannot create /hello: Cannot allocate memory
I went looking for files that that are less than one day old to see if any files were unexpectly being updated and only found this one which seems to be updated on each boot.
# find / -mtime -1 | grep -v "/proc" | grep -v "/dev" | grep -v "/tmp"
/etc/ioctl.save
The log shows all blocks 814-1000 are unusable and some 39-104 unusable.
