Hello everyone, I’m trying to ping my Mangoh Red board but it doesn’t work anymore. I was working on the WiFi connection and after having set my Mangoh Red I wen’t to have a lunch break. When I came back I couldn’t ping my board. I am equiped with a WP7702 and when I open the device manager I can see the SierraWireless DM port. I can’t ping my device nor ssh it. If you need any other information I would be pleased to give it to you! ---

No, it seems the module is crashed and cannot operate normally. That is why you see DM only mode ---

No. The uart debug message may have some hint ---

just connect USB to the CONSOLE connector on mangoh red board. It is using UART2. And you need to make sure AT!MAPUART has been setting UART2 as linux console usage.
