5.1 LFU Firmware Update

Confirm the items below before starting LFU firmware upgrade process:

  • Make sure bootloader firmware already programmed into device via SWD interface.
  • Build application project and generate the .txt file needed for firmware upgrade. Suggest generating both application code 1 and application code 2 for evaluation purpose.
  • Prepare .txt format BSL password file.

Now you can launch PC GUI tool by double-click the file MSPM0_LFU_BSL_GUI.exe at the folder “…\MSPM0 LFU Bootloader Implementation v1.1\BSL_GUI_EXE”. The following steps describe how to perform firmware upgrade process:

  1. Check application code status, which application code is executed or no application code in the device.
  2. Select application code for firmware upgrade evaluation.
    1. If no application code in the device, you can select either application code 1 or application code 2 for firmware upgrade.
    2. If application code 1 is executed in the device, select application code 2 for firmware upgrade.
    3. If application code 2 is executed in the device, select application code 1 for firmware upgrade.
  3. Choose a password file based on the format of the default one in the input folder.
  4. Click the download button to do the firmware update.
