    Hello Richard,
    The watchdog feature built into the SVXLink card does not currently have built-in support in the ORP images, it would be a feature you would need to manually configure.

    They have a starter guide here: http://svxcard.f5uii.net/doku.php?id=en:configuration_watchdog

    That should help you get started. Up to this point we have not really had any requests for the feature in ORP. Just would need some folks to help test and come up with a solution. I’ve been considering adding a field to the board presets table that could reference a bash script to fire off when a specific preset is loaded. This might be able to handle the automation of setting up something board specific like the watchdog on the SVXLink Card. That script would need to probably write out a python file, set permissions on the file and call it on boot up as well as set the referenced GPIO pins.

    Hope that helps.

    Hi Aron
    The guide shown in previous post works but not the test code, all that needs to be done to start the process when the Raspberry boots is to add the line to rc.local shown below just after the lines added in the above guide and before the exit 0 line, the full path has to be given or it doesn’t work

    sudo python /usr/bin/test-watchdog.py

    I had the problem that there was no delay when the process stopped, this was found to be a PCB track fault, set 2 on the MAX6369 was not connected (set 2 had no volts on it) I mention this in case it isn’t a one off and other boards may have the same fault

    So sounds like you got it working. I will try to come back to this for a future release. I am hoping to add a line to run a board specific bash script for certain boards. This would be in the board presets definitions. If a script is referenced then it would run that too. Still considering how to implement this, but I have another piece of hardware that will likely require something like this.
