I was working with the Watchdog under LInux on an armStoneA9 board. I've seen that that the driver is loaded during boot with the nowayout options:
imx2-wdt imx2-wdt.0: IMX2+ Watchdog Timer enabled. timeout=60s (nowayout=1)
But I need to able to close the Watchdog during norml operation. So, I was wondering if there is a parameter for U-Boot or something else, to be able to set the nowayout option to 0. I tried passing 'imx2-wdt.nowayout=0' to 'bootargs' in U-Boot without success.
