Board settings

The FreeRTOS Message Buffers multicore project does not call for any special hardware configurations. Although not required, the recommendation is to leave the development board jumper settings and configurations in default state when running this demo.

Prepare the Demo

  1. Connect a type-c USB cable between the PC host and the MCU-Link USB port (J17) on the board

  2. Open a serial terminal with the following settings (See Appendix A in Getting started guide for description how to determine serial port number):

    • 115200 baud rate

    • 8 data bits

    • No parity

    • One stop bit

    • No flow control

  3. Download the program to the target board.

For detailed instructions, see the appropriate board User’s Guide.
