[Voyage-linux] Watchdog in Alix.3d3

[Konstantinos Birkos]

Hello all,
I have an Alix.3d3 board running Voyage Linux MPD 0.7.
I am writing a program in C in which a certain function writes in 
/dev/watchdog in order to keep the machine working. Actually it is based 
on this tutorial 
http://embeddedfreak.wordpress.com/2010/08/23/howto-use-linux-watchdog/
The computer is supposed to reboot if the function does not reset the 
watchdog timer on time.
Are there any configurations I should make? There is no /dev/watchdog 
file (I can make it with mknod). Am I supposed to disable any watchdog 
keepalive daemons? How can I find my watchdog driver to use it in the 
insmod command? Hands-on instructions would be highly appreciated as I 
am an inexperienced Linux user and a bit confused about the usage of 
geodewdt and sc520_wdt.

Thank you,
Kostas Birkos
