Previously, when I was playing gec2410, I had the idea that I was debugging it in Linux. Because the target board is powered or the serial port sent to the PC during the reset, this was already implemented in windows, so I wanted to see the results in Linux, but after setting up a serial port in Linux, I found no respo

But new problems have arisen, for example, the minicom under the PC and target computer communication or there are some configuration problems, the following is the Linux USB to the serial port configuration and problems:Note: By default, Ubuntu has a USB to
