Dear Scott,
I managed to resolve the heating issue by correcting the error in the PCB. However, I am not able to program the device with its firmware through my XDS110 Debug probe as it is failing in "Test connection". I have already share my schematic that shows SWDCLK, SWDIO and Vcc(ref 5V through 10K resistor) and Vss connections. Could you pl share the connection diagram showing the XDS110 pins that need to be connected to the PCB for a successful connection. Kindly take this as urgent and reply.
