But this is also unused code right now. Enabling on the am335x_evm config is a good place-holder and easy for you to test I assume platform until you can also post the custom board you're working on.

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
