I used nucleus-h743zi2 to evaluate and found that MDK could not recognize stlinkv3 on board. In fact, I have correctly linked USB cable and JP2 jumper cap according to the instructions in the manual and selected stlink for power supply. But I found that when cn13 is connected to a PC, everything becomes normal. The first picture can't work normally. The second picture can work normally after cn13 is connected. The only difference is whether cn13 is linked.
I want to know what caused all this.Is it my setting? Or hardware?
Thank you very much if anyone can help me:grinning_face:
