This article describes specifics for the GigaDevice GD32E103C-START evaluation board.
- J-Link software V6.87a or later
Preparing for J-Link
The GD32E103C-START does not come with a standard debug connector. Therefore, these signals have to be wired manually to connect the J-Link to the evaluation board. The following guide will describe how the GD32E103C-START evaluation board can be connected to your J-Link.
- Populate the the pin headers JP5 and JP6
- Connect the board with jumping wires to your J-Link (see table below)
For information about the J-Link pinout please refer to the following page: J-Link SWD pinout.
|J-Link 20 pin debug interface||Pin on evaluation board|
|Pin 1 (VTref)||+3V3|
|Pin 4 (GND)||GND|
|Pin 7 (SWDIO)||PA13|
|Pin 9 (SWCLK)||PA14|
The result should be looking like this:
- Power the board via the USB port (CN2).
- Verify the Connection with e.g. J-Link Commander. The output should look as follows:
The following example project was created with the SEGGER Embedded Studio project wizard and runs out-of-the-box on the GigaDevice GD32E103C-START. It is a simple blinky application which toggles LED2. The application is linked into the internal flash.
