6.2 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 MCT8316ZTEVM. Consult the
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 J4 of the MCT8316ZTEVM as shown in
3. Connect a micro-USB cable to the MSP430 LaunchPad and the PC.
4. Click on the Build Project icon or "Ctrl" + B to ensure 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.
