2.1.1 Standalone Configuration

Note: The standalone configuration is used for most software development use cases that do not require the use of an external BoosterPack. BoosterPack setup will vary depending on the hardware required.

In this configuration, Code Composer StudioTM connects to the LaunchPad by JTAG and enables software development. The on-board XDS110 debug probe enumerates a virtual COM port (VCP) for communication with the AM261x MCU by UART.

Follow these steps to set up the AM261x LaunchPad in its default configuration:

  1. Collect the required equipment
    1. AM261x LaunchPad (LP-AM261)
    2. 5V/3A USB Type-C power supply
    3. Micro-USB cable
  2. Verify that the switch settings are correct on the LaunchPad
    1. Use SW4 to select the desired boot mode (Boot Mode Selection)
    2. Use S1 and S2 to select the desired ADC voltage reference mode (if applicable for the application) (ADC and DAC)
  3. Connect the 5V/3A USB Type-C power supply to connector J25 of the LaunchPad
  4. Connect the micro-USB cable to connector J24 of the LaunchPad
  5. Verify the power status LEDs (D7, D12, D14, D15, D16) on the LaunchPad are turned on
  6. The LaunchPad is ready for use. Follow the steps in Software to get started on developing software
