How to use both HPS cores on DE1-SoC using DS-5

I'm looking for a way to use both cores on the DE1-SoC board from Terasic using baremetal. I understand how to accomplish the same task using linux and the pthread command, but I want to write programs that uses and debugs both cores. Is there any examples online? I can release cpu1 from reset right after the preloader stage, but I'm lost as to where to go to assign cpu1 to execute certain code fragments.

Hello,

You can enable Symmetric Multi-Processing (SMP) feature to debug your code on Dual ARM. Follow the tutorial here:

https://developer.arm.com/products/software-development-tools/ds-5-development-studio/resources/tutorials/linux-symmetric-multiprocessing-kernel-debug

 

Once you boot your linux, the dual ARM cores will run automatically.

 

Thanks
