Hi @flyant967,
Unfortunately since this morning I CANNOT read the FC via USB with Mission Planner
Edge to Mission Planner connection over USB is not supported. However, you can connect to MP via UDP connection. Here it is described how to do that.
I also tried to flash the firmware but it seems that the USB chipset on the PC board Emlid does not work properly … I’ll make it a reason
Could you please describe this issue in more detail? On which step did you encounter issues?
