[Telink B91 Universal Development Kit] Questions about the functions of TX and RX on the burning tool [Copy link]

In the previous post (https://bbs.eeworld.com.cn/thread-1219308-1-1.html), the program was successfully downloaded using the burning tool. Only the GND and SWM pins were used.

In addition to these two pins, I also saw RX and TX pins. Based on past experience, these should be used for debugging. However, when I checked the device driver, no virtual serial port was found. . .
