Watchdog app in linux
Watchdog app in linux
Is there a command to enable, disable, and reset the watchdog timer in linux?
Re: Watchdog app in linux
There is a generic watchdog daemon available but I don't know if the hardware watchdog in fitPC2 is supported. You can always use a software watchdog. There might be some problems regarding the c states.. just guessing, never used the watchdog.
--edit--
The hardware watchdog of fitpc2 should be supported by mainline kernel. The initial support patch log is available [1]. Denis who shows up in the forums from time to time should know more (if I linked the names correctly).
There is another thread about the configuration going on at [2]. You might want to look at the wiki page [3], too.

watchdog -- watchdog daemon
wd_keepalive -- watchdog keepalive
sbc_fitpc2_wdt -- kernel module to interact with the hardware watchdog
/dev/watchdog -- watchdog device
As far as I understand this (I never used watchdog before, so I might be wrong) you can either use wd_keepalive periodically or just write to /dev/watchdog to reset the timer.
