I have a big size array need put in MSP432 RAM, but when I go into debug session, debug thread will crash, can't run any code ,then will jump to unkown address.

How to build a big size(>8kB) array in MSP432?

    Hi Tan!

    The watchdog might kick in before the array is initialized. To avoid this, insert a pre-init function into your code and stop the watchdog in it. This code will be executed before anything else is done:

    int _system_pre_init( void )
{
  WDTCTL = ( WDTPW | WDTHOLD );

  return 1;
}

    You can place this function somewhere in your main.c file. It does not need an extra function prototype.
