I again got back to the stock firmware and found some more information
about the watchdog. I found the directories ./devices/platform/orion_wdt
./bus/platform/devices/orion_wdt which I believe indicate that they use
the orion_wdt-module compiled in which is also available in the Debian
kernel.
It was possible to use the orion_wdt module from the regular linux-image
package on the busybox shell of the Debian installer and it created
/dev/watchdog as a character device. The binary "qwatchdogd" would also
run in the installer enviroment, pinging the watchdog device. But still,
the device keeps resetting itself after 5 minutes.
After looking again at the init scripts of the stock firmware, I found
the following lines:
/sbin/daemon_mgr qwatchdogd start "/sbin/qwatchdogd -t 1 &"
/sbin/pic_raw 103 # disable pic watch dog
So could it be that there is yet another watchdog present in one of the
micro controllers used in the device? I also tried copying the pic_raw
binary over to the Debian installer but this one is linked against way
too much shared libraries that are not present in the installer. Any
ideas how to proceed from here?
