Minimum requirements

  • J-Link software V6.84 or later

Preparing for J-Link

The IndieSemi Realplum EVK does not come with a standard debug connector but populates the debug SWD signals on a 4 pin header (CON1). Therefore, it can be manually wired in case J-Link shall be connected to it. Apart from the debug signals, the board does not route Vdd (3.3V) to VTref by default which is required for the J-Link. The following guide will describe how the Realplum EVK can be connected to your J-Link Base V10 or higher. Other J-Links might work as well but wiring might be slightly different. All needed information can be found in the probe related documentation.

  • Solder a two pin header to J8 (VDD3V3)
  • Close the soldered header using a jumper
  • Now connect the board with e.g. jumperwires to your J-Link probe.
  • The following table shows how the Signals should be connected on both the board and J-Link side.
J-Link 20 pin debug interface Pin on eval board pads
Pin 1 (VTref) Pin 1 (Vdd)
Pin 4 (GND) Pin 4 (GND)
Pin 7 (SWDIO) Pin 2 (SWD)
Pin 9 (SWCLK) Pin 3 (SWC)

The resulting connection will then look like this:

  • Power the board via the USB-C port.
  • Verify the Connection with e.g. J-Link Commander. The output should look as follows:

Example Project

The following example project was created with the SEGGER Embedded Studio project wizard and runs out-of-the-box on the IndieSemi Realplum. It is a simple Hello World sample linked into the internal flash. SETUP
