Hi all, On my board (at91sam9263ek) I have enabled the watchdog. It will reset the processor after about 16 seconds. It looks like it is working but if I'm writing a large file into nand it seems that the watchdog is not reset and finally my processor resets. I've patched it, but I'm not sure if it is the right way to do it this way...
So far we've been putting the watchdog resets in higher-level functions. It looks like the block-skipping versions have them, but the non-block-skipping versions don't (and the former will call the latter if it doesn't see any bad blocks).
So I think this should go in nand_read() and nand_write(). If things hang up inside the low-level wait that should trigger the watchdog.
Oh, and all patches require a sign-off, and the text above the patch should be what is intended to go in the git changelog, with any additional comments/greetings/etc below a "---" line.
