Deploy to MSP432P401R

General hardware requirements:

1. Development kit: TI MSP432P4R01 LaunchPad

Micro Speech example hardware requirements:

1. Add-on board: TI BOOSTXL-AUDIO

Software requirements:

1. Download and install Code Composer Studio 11+ (instructions)
   • See section 3.2.3.5. Device Support - when prompted select "SimpleLink MSP432 low power + performance MCUs" component before proceeding
2. Download and install the latest MSP432P401R SDK (instructions)
3. Install the GCC toolchain
   1. Launch Code Composer Studio
   2. When prompted for a workspace directory, provide a new directory name to create a new workspace (or select an existing workspace directory), and press "Launch" - after which the main IDE windows will become visible
   3. Go to the Help menu and select - Install GCC ARM Compiler Tools… -> a window titled "Install" will open
   • On the bottom, uncheck "Show only the latest versions of available software"
   • In the middle, expand the "ARM GCC Tools" tree
   • Check "ARM GCC Compiler Tools" - Version: "9.2.1.2009-q4-major"
   • Press the "Next" button to finish the installation
   • Restart Code Composer Studio

Generate, build and flash the project:

1. Launch Code Composer Studio
2. When prompted for a workspace directory, provide a new directory name to create a new workspace (or select an existing workspace directory), and press "Launch" - after which the main IDE windows will become visible
3. In the main menu, choose Tools->Import CCS Projects...
4. In the "Import CCS Projects" dialog, put the path to the repository in the "Select search-directory" field with the correct target - e.g. ~/repos/tensorflow-lite-micro-examples/targets/MSP432R01
5. The "Discovery Projects" list should become populated with the available projects
6. Choose a project and click the "Finish" button

Build and Flash:

In Code Composer Studio, select Run->Debug

• CCS will build the project and flash it to the device
• When flasing is done, select Run->Terminate
• Reset the board manually

Do the following to display the program output (per your computer OS):

• Linux
  • Execute the following command in a terminal

    screen /dev/ttyACM0 115200
    

• Windows
  • Open "Device Manager" to determine the COM port name, the device is called "XDS110 Class Application/User UART (COM#)"
  • Use a serial terminal emulator to display the output (e.g. TeraTerm, PuTTy, etc)
