Running Only Core 1 on MPC5777C with GHS Compiler

Santhoshraj — Mon, 07 Oct 2024 09:36:06 GMT

Hi,

I'm working with the MPC5777C evaluation board and the GHS compiler. I need to configure my project to run only on core 1.

Could someone please guide me on how to set this up? Specifically, I would like to know:

Thank you!

Hello,

It is quite simple.

You will boot on core0 by default. Once you have all initialization done and core 1 active.

You simply put core0 clocks in halt

and then put core0 into reset:

Best regards,

Peter

Hi,

Any alternate solution. Because SIU.HLT1.B.CORE0=1; condition is Not working to halt the core0 or please provide me any example code

Thank you!

Hello,

In the reference manual:

So you have to execute wait instruction on the core0.

Then you will ask for halt reques in SIU_HLT1

You can see I have executed wait from core1, then I ahve switched to core2 and asked for halt of the clocks from debugger:

After that core0 is halted.

Best regards,

Peter
