we have a strange effect while using the colibri hardware watchdog on /dev/colibri-watchdog.
We tested/triggered the watchdog with a python script. This is working. When stopping the feeding the system restarts. So far so good. But if we have an opened file (e.g. nano dummy.txt) and the watchdog reboots in background, we are not able to login after reboot. We get a login prompt but the root credentials (using pwd) are not accepted anymore: Wrong username or password.
thank you for the response. I Think this issue has been “resolved”. After the reboot caused by watchdog, something in the UART serial console has changed. Due to this, pasting of e.g. passwords wont work anymore…until you restart the terminal (reset the session). After that, everything is working fine again.
