PROJECT DESCRIPTION

We'll walk you through the process of setting up a microcontroller unit (MCU) using J-Link in detail. Follow these steps to ensure a smooth setup.

1. Check what you need

  • J-Link Debugger: J-Link debugging tool provided by SEGGER.
     
  • MCU Development Board: Development board with target MCU.
     
  • USB cable: Cable to connect the J-Link to the PC.
  • J-Link Software Package: Available for download from SEGGER's official website.
  • Communication interface cable: Cable for connecting the MCU and J-Link, such as SWD, JTAG, etc. (depending on the development board).

 

2. Install J-Link Software and Drivers

  • Visit the SEGGER official website: Access the SEGGER J-Link download page.
  • SEGGER - The Embedded Experts - Downloads - J-Link / J-Trace
  • Download the software: Download the J-Link software package for your operating system.
  • Run the installation file: Run the downloaded installation file and follow the on-screen instructions to complete the installation.
  • Confirm Driver Installation: The installation process will automatically install the drivers, and it is recommended that you reboot your PC after the installation is complete.

 

3. Connect the J-Link and MCU

  • J-Link Connection: Connect the J-Link device to the PC using a USB cable.
  • MCU Connection: Connect the J-Link to the MCU using the debugging port (SWD, JTAG, etc.) on the development board.
  • Make sure the power supply and GND connections are correct when connecting.
  • Verify the connection: Verify that the J-Link software recognizes the J-Link device. You can run J-Flash to check the connection status.

 

4. J-Link Software Setup

  • First, create a project.
  • After running the program, J-Link needs to specify the model of the target MCU, we specify W55RP20.
  • Interface settings:
    Set the communication interface (SWD) with the MCU.
    Set Speed: Set the debugging speed. Typically, you use the default speed (for example, 4000 kHz), but you can adjust it as needed.

 

5. Test the connection

  • Verify device connectivity: Enter the connect command to verify that the J-Link connects to the MCU normally. If successful, the information of the MCU will be output.
  • Memory Read/Write Test: A simple memory read/write command can be used to further verify the connection status.You can read the address 0x10000000 to get the value.

  • Development board manuals: Refer to the manual for the MCU development board you are using to understand pin connections and settings.
  • Online communities and forums: You can get additional help from communities that share experiences from developers using the same MCU and J-Link.
  • Follow these steps to successfully register your J-Link and MCU and set up your debugging environment
