Hello everyone. I ran into a problem when using J-Link to program GD32H7 controllers.
The fact is that I cannot connect to the controller using J-Flash until I connect using IAR, which also uses J-Link.
I have fixed the J-Flash and IAR logs and I see that they have a slightly different connection process, but I do not know how to get J-Flash to use IAR logic.
I will attach the recorded logs below. This happens with the GD32H759I-EVAL developer board, and also with the device that I made myself based on GD32H757ZMT6.
