Hi,

I am using nxp im6ul and I am facing an issue with the watchdog described here:

https://community.nxp.com/message/868361

If I enable the watchdog using the WCR_WDE flag, then the watchdog cannot be stopped later by kicking it with writing anything to /dev/watchdog from rootfs.

Therefore, I think that the only way of starting the watchdog would be to write V to /dev/watchdog from uboot. So if starting the rootfs fails, then the system restarts and uboot is responsible to fix the rootfs.

The question is, how can I write a V to /dev/watchdog from uboot? Or how can I start the watchdog from uboot in a similar way?

Thanks
