5.2.1.1 Step by Step Using the Demo

These are the steps on how to use the flash-based UART plug-in interface demo for MSPM0G3507:

  1. Import the flash-based UART plug-in interface demo into CCS from the SDK.

    <…\mspm0_sdk_xxxx\examples\nortos\LP_ MSPM0G3507\bsl\ bsl_uart_flash_interface >

  2. Make any needed changes and build the project.
  3. Do a factory reset to clear any static flash write protection settings in NONMAIN. If the device is blank, this step can be skipped. For more information on the steps to perform this operation, see Section 6.2.
  4. Download the UART plug-in code into flash. The important thing downloading the image is to enable NONMAIN flash erase shown in Figure 3-4. The plug-in interface demo cannot be debugged directly. For more details, see Section 5.2.1.2.
  5. Prepare one LP-MSPM0G3507 launchpad and use the BSL host demos to do the firmware update. For more details, see Section 4.1.3 (MCU as host) or Section 4.2.2 (PC as host).
