Re: RevPi Compact Crash

Hi Nicolai

Nothing extraordinary. The RevPi Compact acts as a SCADA for a heating control. Real time processing is not used. The application is based on Node-RED: Temperature acquisition, communication (Modbus, M-Bus, MQTT), control some valves and pumps.

Best regards,
Michael

RevPi Compact does not boot after changing "Max CPU clock rate"

Hello

I have changed the setting "Max CPU clock rate" from the web interface. The RevPi Compact does not boot after this modification. Is there a way to revert this setting in the file system. I don't want to overwrite the image.

Typically the connection is established after a manual restart of Node-RED (systemctl restart node...
