+MSPM0G3507 LaunchPad
+########################
+
+Overview
+********
+
+MSPM0G350x microcontrollers (MCUs) are part of the MSP highly integrated, ultra-low-power 32-bit MCU
+family based on the enhanced Arm® Cortex®-M0+ 32-bit core platform operating at up to 80-MHz frequency.
+These cost-optimized MCUs offer high-performance analog peripheral integration, support extended temperature
+ranges from -40°C to 125°C, and operate with supply voltages ranging from 1.62 V to 3.6 V.
+The MSPM0G350x devices provide up to 128KB embedded flash program memory with built-in error correction
+code (ECC) and up to 32KB SRAM with ECC and hardware parity option. These MCUs also incorporate a
+memory protection unit, 7-channel DMA, math accelerator, and a variety of high-performance analog peripherals
+such as two 12-bit 4-Msps ADCs, configurable internal shared voltage reference, one 12-bit 1-Msps DAC, three
+high speed comparators with built-in reference DACs, two zero-drift zero-crossover op-amps with programmable
+gain, and one general-purpose amplifier. These devices also offer intelligent digital peripherals such as two
+16-bit advanced control timers, five general-purpose timers (with one 16-bit general-purpose timer for QEI
+interface, two 16-bit general-purpose timers for STANDBY mode, and one 32-bit general-purpose timer), two
+windowed-watchdog timers, and one RTC with alarm and calendar modes. These devices provide data integrity
+and encryption peripherals (AES, CRC, TRNG) and enhanced communication interfaces (four UART, two I2C,
+two SPI, CAN 2.0/FD).

+Details on the MSPM0G3507 LaunchPad can be found on the `TI LP_MSPM0G3507 Product Page`_.
+
+Supported Features
+==================
+
+The MSPM0G3507 LaunchPad development board configuration supports the following hardware features:
+
++-----------+------------+-----------------------+
+| Interface | Controller | Driver/Component |
++===========+============+=======================+
+| NVIC | on-chip | nested vectored |
+| | | interrupt controller |
++-----------+------------+-----------------------+
+| SYSTICK | on-chip | system clock |
++-----------+------------+-----------------------+
+| UART | on-chip | serial |
++-----------+------------+-----------------------+
+| GPIO | on-chip | gpio |
++-----------+------------+-----------------------+
+| PINMUX | on-chip | pinctrl |
++-----------+------------+-----------------------+
+
+More details about the supported peripherals are available in `MSPM0G3507 TRM`_.
+Other hardware features are not currently supported by the Zephyr kernel.
+
+Building and Flashing
+*********************
+
+Building
+========
+
+Follow the :ref:`getting_started` instructions for Zephyr application development.
+
+For example, to build the :ref:`hello_world` application for the MSPM0G3507 LaunchPad:
+
+.. zephyr-app-commands::
+ :zephyr-app: samples/hello_world
+ :board: lp_mspm0g3507
+ :goals: build
+
+The resulting ``zephyr.bin`` binary in the build directory can be flashed onto
+MSPM0G3507 LaunchPad using the steps mentioned below.
+
+Flashing
+========
+
+`UniFlash`_ is used to program the flash memory. Only bin loading is currently supported.
+Make sure to select the checkbox for binary loading.
+
+Debugging
+=========
+
+The flashing method described above does not include symbols. Thus, debugging requires an additional step to load the symbols.
+This section shows how to debug the MSPM0G3507 LaunchPad board using `CCS IDE`_. More information
+on debugging using CCS can be found in `CCS User's Guide`_.
+
+In general, the steps for debugging in CCS are:
+
+ 1. Open CCS
+ 2. Go to Window > Show View > Target Configruation
+ 3. Import target confguration by right clicking User Defined, selecting Import target configuration and pointing to the lp_mspm0g3507/support/MSPM0G3507.ccxml
+ 4. Launch target configuration by right clicking the new MSPM0G3507.ccxml file and clicking Launch target configuration
+ 5. Plug in the device and connect to it by going to Run > Connect Target
+ 6. Go to Run > Load > Load Symbols and load in the zephyr.elf file loaded
+ 7. Use CCS to debug
