| 18:06.52 | aandrew | good afternoon everyone |
| 18:07.51 | aandrew | is there some magic involved in using the kernel watchdog device? I'm on a Zynq, using the zynq watchdog (cdns-wdt) driver |
| 18:08.06 | aandrew | if I open /dev/watchdog and write to it periodically, it does not reboot (this is expected). |
| 18:08.19 | aandrew | if I stop writing to it and just wait, the system will *hang* |
| 18:08.40 | aandrew | if I close the device, I get the warning that the wd counter didn't stop (it's ok) and then it reboots as expected when the watchdog times out |
| 18:10.45 | aandrew | is the intended operating mode to periodically open, write, close instead of open and periodically write, never closing? |
