DebuggerHeldCoreLoop

Hello.

When I was learning S32DS Startup_cm7.s files, I encountered a problem. I can't understand the function shown in the picture above.

First ：What is the function of DebuggerHeldCoreLoop?

Second: RESET_CATCH_CORE is an Random number or Specific number?

Three: Why compare R0 with 0x5A5A5A5A?

Expect to receive a reply.

thanks

As you can see in the system.c file

The RESET_CATCH_CORE variable can be overwritten by the debugger to 0x5A5A5A5A, which will catch the execution in that loop.

Regards,

Daniel
