MSPM0L1304: Programming Method Clarification for MSPM0L1304TDYYR

Part Number: MSPM0L1304

We are using the MSPM0L1304TDYYR for our latest project and would like to clarify the programming approach.

Could you please confirm the following:

  1. Programming Interface:
    Can the device be programmed using the SWD interface (SWDIO/SWCLK) with an XDS110 Debug Probe or ST-Link Programmer, or is UART connectivity required for programming?
  2. BSL Usage:
    We are planning to use the BSL_UART pin as an ADC input in our design. In this case, can we rely solely on SWD for programming and debugging without requiring the UART-based BSL interface?
  3. Factory Bootloader (FSBL/BSL):
    Please confirm whether a factory bootloader (BSL/FSBL) is pre-programmed and available in the raw device, and if so, what interfaces it supports by default.

Your clarification will help us finalize the hardware design and programming strategy.

    Hi,

    The device can be programmed through:

    1. SWD interface (XDS110, Jlink supported cannot use ST-Link)
    2. BSL like UART I2C interface.

    Yes. You can. SWD and BSL are completely independent burning methods. You only need to choose one of them.

    We do support ROM BSL which is a factory bootloader.

    If you're choosing BSL to flash the MCU, then please reserve below pins:

    For details, you can refer to datasheet: MSPM0L130x Mixed-Signal Microcontrollers datasheet (Rev. D)
