.. _hello_demo: Hello demo ==================== 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. Board Setting ------------- BOOT_PIN should be configured to 0-OFF, 1-OFF Generate, Build and Debug Multi-core projects --------------------------------------------- Please reference :ref:`Multicore General Description ` Running Results --------------- - Taking HPM6750EVKMINI as an example, when the project runs successfully, the serial port terminal will output the following information: .. code-block:: console 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.
