7.2 Using the eZ-FET to Program the MSP430FR2355

The eZ-FET Debug Probe on the MSP430FR2355 LaunchPad uses a SPI-by-Wire JTAG interface to program the MSP430FR2355 MCU on the MCT8329EVM. Consult the MSP430 LaunchPad Development Kits for MSP430 LaunchPads that include an onboard eZ-FET Debug Probe.

  1. Remove the GND, 3V3, SBWTDIO, and SBWTCK jumpers from the MSP430 LaunchPad.
  2. Connect the top pins on the eZ-FET side of the LaunchPad of the GND, 3V3, SBWTCK, and SBWTDIO signals to their respective pins on J7 of the MCT8329EVM as shown in Table 7-1 and Figure 7-2.
  3. Connect a micro-USB cable to the MSP430 LaunchPad and the PC.
  4. Click on the Build Project icon or Ctrl + B to verify that the project builds successfully. Accept any updates if needed from the Console.
  5. Click on Debug Project to set up a debug session and press the Play button to run the code.
  6. Stop the debug session, close Code Composer Studio, disconnect the SPI-by-Wire jumpers, and unplug the micro-USB cable from the MSP430 LaunchPad.
