I m working on IOT device dell gateway in that Ubuntu Core 16 OS is there and I want to use Hardware Timer for any unexpected crashes or etc…
- So I have opened “/dev/watchdog” but it will busy always and get failed.
So i don’t know why its happening , is there any security in Ubuntu Core 16 to access some path.
2) I have tried some command to change RunTimeWatchdogSec but It could same nothing change.
snap set core watchdog.runtime-timeout=10m
systemctl show | grep -i watchdog
- In Dell gateway User manual there is one WDT and it is provide some Enable/Disable policy and some configuration files like /etc/systemd/system.conf.d etc… so IF i m enable this Timer so after words is that working same as our OS WDT ???
please let me know.
