# 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[Multicore General Description.md](../README_en.md) ## Running Results - Taking HPM6750EVKMINI as an example, when the project runs successfully, the serial port terminal will output the following information: ```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.
