Example Summary

This demo shows how to program a MSPM0C1104 MCU using a LP-MSPM0C1104 as host by BSL UART interface. It can support hardware invoke or software invoke.

More information please refer to MSPM0 Bootloader (BSL) Implementation or MSPM0 Bootloader user’s guide

Pin Peripheral Function LaunchPad Pin LaunchPad Settings
PA16 GPIOA PA16 N/A
  • PA16 is connected to S2 button to GND with no external pull resistor
    • Press S2 button to connect pin to GND
    • Don’t use S2 button if not needed by application
PA2 GPIOA PA2 N/A Just hardware invoke needed
PA4 GPIOA PA4 N/A Just hardware invoke needed
PA22 GPIOA PA22 N/A
  • PA22 can be connected to LED1
    • J7 ON Connect to LED1
    • J7 OFF Disconnect from LED1
PA24 UART0 RX N/A
  • PA24 can be used as UART RX connected to boosterpack connector
PA27 UART0 TX N/A
  • PA27 can be used as UART TX connected to boosterpack connector
PA20 DEBUGSS SWCLK J2_13
  • PA20 is used by SWD during debugging
    • J101 15:16 ON Connect to XDS-110 SWCLK while debugging
    • J101 15:16 OFF Disconnect from XDS-110 SWCLK if using pin in application
PA19 DEBUGSS SWDIO J2_17
  • PA19 is used by SWD during debugging
    • J101 13:14 ON Connect to XDS-110 SWDIO while debugging
    • J101 13:14 OFF Disconnect from XDS-110 SWDIO if using pin in application

Device Migration Recommendations

This project was developed for a superset device included in the LP_MSPM0C1104 LaunchPad. Please visit the CCS User’s Guide for information about migrating to other MSPM0 devices.

Low-Power Recommendations

TI recommends to terminate unused pins by setting the corresponding functions to GPIO and configure the pins to output low or input with internal pullup/pulldown resistor.

SysConfig allows developers to easily configure unused pins by selecting Board→Configure Unused Pins.

For more information about jumper configuration to achieve low-power using the MSPM0 LaunchPad, please visit the LP-MSPM0C1104 User’s Guide.

Example Usage

Connect the hardware that descriped in the document. Compile, load and run the example. Push the S2 button to start program MSPM0C1104. Note: if use software trigger need the application code(include software invoke) exist on the chip.
