| |
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! root@odroidxu4l:~# root@odroidxu4l:~# root@odroidxu4l:~# root@odroidxu4l:~# root@odroidxu4l:~#
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. ----------------------------------------------------------------------------------------------- root@odroidxu4e:~# echo 4 > /dev/watchdog [ 639.192617] [c3] watchdog watchdog0: watchdog did not stop! root@odroidxu4e:~# root@odroidxu4e:~# root@odroidxu4e:~# ----------------------------------------------------------------------------------------------- I would like to know what is way board reset after watchdog reset after timeout.
Best Regards -Anand Moon
