Need Help with Locking Core 0 and Running Only Core 1

[Santhoshraj]

Hi,

I am currently working on a project using the GHS (Green Hills Software) compiler where Core 0 is active. I need to lock Core 0 to prevent it from executing while I initialize and run Core 1. but I’m not sure if I'm implementing it correctly. Can someone provide an example of how to properly start core 1, or point me to relevant documentation

Thank you!

Hello,

I need to lock Core 0 to prevent it from executing while I initialize and run Core 1.

All you need to do in put it into halt state.

To do so you can execute wait instruction:

 asm(" wait");

or

asm ("halt");

This will stop execution of instructions on core. This is commonly used in the idle task of OS.

For more details please refer to core reference manual of e200z7.

Best regards,

Peter
