19.2. Console Coremark Demo
19.2.1. Overview
Multi-core Console coremark example project runs the “coremark” example on core0 and core1.
In this project:
The multi-core coremark will run automatically when the demo starts to run, and the dual-core coremark result will be printed out to the console
The application accept next request to run this demo again if detecting any inputs from the console UART.
19.2.2. Board Setting
BOOT_PIN should be configured to 0-OFF, 1-OFF
19.2.3. Generate, Build and Debug Multi-core projects
Please referenceMulticore General Description.md
19.2.4. Running the example
Taking HPM6750EVKMINI as an example, when the project runs successfully, it will print out the following result:
