1. Would you please attached the schematic of your board? So that I can check the debug port and circuit of minimum system.

2. The Segger J-Link Commander is able to flash bin file to MCU. I have not meet such phenomenon before.  Please make sure the connector well connected to MCU during programming.

3. When not powered, VCC short to GND measured by multimeter? After powered, will the temperature of 5v or 3.3v LDO become very hot?

Best Regards,

Robin
