banana R1 / hardware watchdog

[Rui Ribeiro]

Hi,

 

Was anyone able to use the watchdog in the Lamobo/banana pi r1? If not is anyone using some hardware that resets it/an hardware watchdog?

A20 hardware watchdog is supported by both kernel families and should work if configured correctly.

"dmesg | grep watchdog" on mainline:

[    3.448805] sunxi-wdt 1c20c90.watchdog: Watchdog enabled (timeout=16 sec, nowayout=0)

How to configure it depends on your OS release.

Thanks Zador. Using Armbian/Debian 8.

 

/dev/watchdog exists, so it is a matter of :

 

sudo apt-get install watchdog

 

and the take out the comment in the line

 

watchdog-device = /dev/watchdog

 

and then

sudo service watchdog restart

On Jessie alternatively you can configure watchdog in "/etc/systemd/system.conf", options "RuntimeWatchdogSec" and "ShutdownWatchdogSec"

Thanks, but I am no fan of systemd. I am pinning it to -1.
