Hi All,
Using microSD card when I try to write into /dev/watchdog device
it triggers reboot of the board after timer expires.

root@odroidxu4l:~# echo 3 > /dev/watchdog
[ 1659.021844] watchdog: watchdog0: watchdog did not stop!

U-Boot 2016.03-00665-g563d8d9-dirty (Apr 04 2016 - 22:27:07 +0930) for
ODROID-XU
3
CPU: Exynos5422 @ 800 MHz
Model: Odroid XU3 based on EXYNOS5422
Board: Odroid XU3 based on EXYNOS5422
Type: xu4
DRAM: 2 GiB
-----------------------------------------------------------------------------------------------
But when I try this on eMMC it just freezes.
I know we have to set and unset gpio pin (SD_0.RST) to trigger reset
before reboot.
