Hi,
I'm using an UltraZed with IOCC board, with petalinux 2017.4.
In petalinux there is a command called 'watchdog':
sh$ watchdog
BusyBox v1.26.2 (2018-02-20 14:16:42 IST) multi-call binary.
Usage: watchdog [-t N[ms]] [-T N[ms]] [-F] DEV
Periodically write to watchdog device DEV
-T N Reboot after N seconds if not reset (default 60)
-t N Reset every N seconds (default 30)
-F Run in foreground
Use 500ms to specify period in milliseconds
I'm expecting the following command to reboot in 5 seconds:
sh$ watchdog -T 5 -t 60 /dev/watchdog0
But actually, nothing happens!
I was adding the following into my system-user.dtsi:
&watchdog0 {
status = "okay";
reset-on-timeout;
};
I'm suspecting that no hw clock is assigned to it, but I have no idea which clock should be declared for it.
any idea please??
