Minimum requirements

  • 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.

Pin 1 (VTref) +3V3
Pin 4 (GND) GND
Pin 7 (SWDIO) PA13
Pin 9 (SWCLK) PA14

The result should be looking like this:
