2.1.3 Configuration 3: Baseboard Configuration

The baseboard configuration is used for to interface the controlSOM directly to a compatible baseboard or docking station. Power is provided to the controlSOM through the baseboard. An emulation debug-probe such as the XDS110ISO-EVM is required to provide debug connectivity to the MCU. The XDS110 debug-probe and baseboard are sold separately.

In this configuration, Code Composer Studio Theia connects to the controlSOM via JTAG and enables software development. The XDS110 debug-probe also enumerates a virtual COM port (VCP) for communication with the MCU via UART.

Follow the steps in the baseboard user's guide to enable this configuration.

  1. The following equipment is required:
    1. AM261x controlSOM (AM261-SOM-EVM)
    2. C2000, Sitara controlSOM compatible base board
    3. XDS110 isolated debug probe (XDS110ISO-EVM)
    4. One USB Type-C cable
  2. Verify the switch settings are correct on each EVM.
    1. AM261-SOM-EVM:
      1. Use SW1 to select the desired boot mode (Section 2.7).
      2. Use S1, S2, S4 to select the desired ADC voltage reference mode (if applicable for the application) (Section 2.9.7).
    2. XDS110ISO-EVM:
      1. S1 selects JTAG mode; set to JTAG mode.
      2. S2 enables UART, SPI connection; set to ON mode
  3. Set up the base board as per the user's guide instructions.
  4. Attach the AM261x ControlSOM to the baseboard.
  5. Make sure the controlSOM is correctly oriented. The J1 header on the controlSOM connects with the J1 header on the baseboard.
  6. Connect the XDS110ISO-EVM into the XDS Debug Header (J4) of the controlSOM.
  7. Connect the USB cable into connector J5 on the XDS110 isolated debug probe. The XDS110 isolated probe and the controlSOM are powered on
  8. Provide power to the base board as per the user's guide instructions.
  9. Verify the power status LEDs (D5, D6, D7) on the controlSOM are turned on.
  10. The controlSOM is ready for use. Follow the steps in Section 3 to get started on developing software.
