3.2.1 Prepare the Image File and Password File

Before downloading the firmware with the GUI, prepare two files: the application firmware file and the BSL password file.

The GUI (MSPM0_BSL_GUI.exe) supports only the TI-TXT format. For details on how to generate this format image file with CCS, see 6 in Section 3.1.3.

The format of the password file is similar to the TI-TXT format as shown in Figure 3-6. The BSL password is defined in the Non-Main memory. For more information, see the technical reference manual [1][2] or the bootloader user's guide [3]. If the BSL password is not the default (all 0xFF), modify the password file. A default password file named BSL_Password32_Default.txt is available in this folder: < …\mspm0_sdk_xxxx\tools\bsl\BSL_GUI_EXE\Input >.
