MSPM0L2228 Launchpad
Overview
MSPM0Lx22x microcontrollers (MCUs) are part of the highly integrated, ultra-low-power 32-bit MSPM0 MCU family based on the Arm® Cortex®-M0+ 32-bit core platform, operating at up to 32MHz frequency. These MCUs offer a blend of cost optimization and design flexibility for applications requiring 128KB to 256KB of flash memory in small packages (down to 4mm x 4mm) or high pin count packages (up to 80 pins). These devices include a VBAT backup island, an optional segmented LCD controller (on MSPM0L222x), cybersecurity enablers, and high-performance integrated analog, and provide excellent low-power performance across the operating temperature range.
Up to 256KB of embedded flash program memory with built-in error correction code (ECC) and up to 32KB SRAM with ECC and parity protection is provided. The flash memory is organized into two main banks to support field firmware updates, with address swap support provided between the two main banks. An additional 32-byte backup memory is provided in the VBAT island, supplied by the VBAT pin and retained even when the main supply (VDD) is lost.

Building and Flashing
Building
Follow the Getting Started Guide instructions for Zephyr application development.
For example, to build the blinky application for the MSPM0L2228 LaunchPad:
# From the root of the zephyr repository
west build -b lp_mspm0l2228 samples/hello_world
The resulting zephyr.bin binary in the build directory can be flashed onto
MSPM0L2228 LaunchPad using the steps mentioned below.
Flashing
Open OCD is used to program the flash memory on the devices. It may be necessary in earlier versions to use a branch of open OCD onto the device.
Before OpenOCD is public, one can clone This Repo, and then this can be built with
$ cd <cloned_OPENOCD_dir>
$ ./bootstrap (when building from the git repository)
$ ./configure
$ make
$ sudo make install
Then after the build, it is possible to flash the device by passing additional arguments to the flash command
$ west flash --openocd <path to cloned dir>/src/openocd --openocd-search <path to cloned dir>/tcl
Flashing using JLINK
$ west flash --runner jlink
Debugging
You can debug an application in the usual way. Here is an example for the Hello World application.
# From the root of the zephyr repository
west build -b lp_mspm0l2228 samples/hello_world
west debug
