This tool is meant to flash the MSPM0 MCU firmware on a phyVERSO EVCS controller board via TIs BSL UART protocol. Some commands like read_binary_version still have hardcoded offsets, where the mspm0_bsl_flasher tool reads the firmware binaries meant for this EVCS controller board. So if you try to fork/base your own flashing tool on this, you will have to modify offsets/lengths for this in your flashing tool implementation as well as modify your FW linker script accordingly.
Depending on the way you configure your cmake build, you would need to have one of the following available on the target hardware for accessing RESET/BSL pins:
- libgpiod-tools v1.x.x
Without setting any cmake options/variables, the mspm0_bsl_flasher would assume that you have libgpiod-tools v1.x.x installed on your target system and will use gpioset to set RESET and BSL pins accordingly to bring the MSPM0 MCU into BSL bootloader mode.
By default, it is assumed that the RESET is available on gpiochip1 line 23 and BSL pin is on gpiochip1 line 12. You can change those values by respectively setting the following parameters:
-D_GPIO_BSL_BANK_=
-D_GPIO_BSL_PIN_=
-D_GPIO_RESET_BANK_=
-D_GPIO_RESET_PIN_=
