20.7. Hello demo

20.7.1. Overview

The multi-core example project runs a serial port echo example on Core0 and a GPIO toggles RGB LEDs in GPTMR interrupt example on Core1.

In this project:

• The serial port outputs “hello world”; Manually input the stirng information through the keyboard and print it through the serial port

• The RGB leds are switching among RED, GREEN, BLUE respectively.

20.7.2. Board Setting

BOOT_PIN should be configured to 0-OFF, 1-OFF

20.7.3. Generate, Build and Debug Multi-core projects

Please referenceMulticore General Description.md

20.7.4. Running Results

• Taking HPM6750EVKMINI as an example, when the project runs successfully, the serial port terminal will output the following information:

      Copying secondary core image to destination memory: 0x1180000
      Hello world for multicore! Secondary core control RGB leds blinking...
  

• The RGB leds are switching among RED, GREEN, BLUE respectively.
