GD32L233C-START Development Board Study Notes ( Part 3 )

1. Introduction to GD32L23C-START development board:

• The GD32L233C-START development board comes with a program debugging tool, so there is no need to connect a debugger separately;
• The GD32L233C-START development board is equipped with three USB interfaces, which can realize debugging, ch340 serial port, and ordinary USB port respectively;
• The GD32L233C-START development board is the smallest system board, and the program can be burned and debugged after power-on;
• The GD32L233C-START development board comes with a test LED light and buttons, which can debug some IO interface functions;

1. GD_Link part:

The GD_Link emulator is immediately displayed in the MDK project : CMSIS-DAP ARMv8-M Debugger .

11. 2. Some doubts about GD_Link :

• The JP100 interface on the GD_Link is connected to the SW interface of the MCU according to the schematic diagram , but when tested with a multimeter in actual use, it was found that there was no connection, and the interface is a surface-mount pad, which is a bit useless.

• When it comes to the MCU part, the network diagram becomes other labels. If the product is in mass production, the utilization rate of GD_Link is not high.

• From the development board logo, we can see that the development board is 2021-10 , but it uses a Mini-B USB port socket. This kind of Mini-B USB cable is very rare. It took me a long time to find it. It feels a bit retro.

There are relatively few Mini-B interfaces, and it is hard to find cables.

Yes, it took me a long time to find it.
