I think that this patch has some problem because watchdog reset is
in getc code. Did you try to paste very long string when it is enabled? You need to
avoid reset when it is not needed
I think, I do not understand you ... this is for all watchdogs the case ...
I currently pasted a 500 bytes long string, seeing no problems with the watchdog...
OK, maybe was a problem of my version. I have done the same driver 2
month ago and tested on omap3. I optimize the watchdog reset using time delaying.
BTW if it works I have no other comments. Sorry for the noise
Maybe you have a chance to try this patch on your hw?
Yes I can or I can ask.
