Hello,

 

We try to Open WatchDog on Linux Application. Our platform is i.MX6 Sabre SDB and Linux kernel version is 3.0.5

Code Snippet "fd = open(/dev/watchdog,O_RDWR)". Linux rebooted after 60 Sec, Hope this is the default time period of WatchDog Timer.

But after reboot, the bootloader shown the previous reset status as Power - On Reset, instead of WDOG reset.

Can you please check this issue..Why it previous reset status become Power on Reset
