| |
I am working on custom imx6 board with linux 3.14.52. I am trying to use hardware watchdog from uboot. I am able to enable with success the watchdog in uboot. Booting with an invalid kernel will reboot the board after timeout. Problem is in linux side. I have some random reboot sometimes. I am not able to understand where is the code to ping the uboot hardware watchdog in linux kernel.
* There is no /dev/watchdog entry associate to my uboot watchdog (there are entries only for pmic watchdog) * Only code where I find ping of uboot watchdog seems to be in imx2 watchdog driver. But this driver is not enable in my kernel config. But if noone is pinging the watchdog, why I am able to play with my board during few hours sometimes ??
Thanks, Arthur.
