Hard Reset on a MK60 with Processor Expert Generated Code

I have a new board and when I go to disable the watchdog - it throws a hard reset.  This is using Processor Expert generated code.

 

Here is the generated startup:

 

void __thumb_startup(void);

 

__asm void __thumb_startup(void) {

  IMPORT  __init_hardware

  IMPORT  __main

  LDR     R0, =__init_hardware

  BLX     R0

  LDR     R0, =__main

  BX      R0

  ALIGN 4

}

 

And the rest of it:

 

/*lint -esym(765,__init_hardware) Disable MISRA rule (8.10) checking for symbols (__init_hardware). The function is linked to the EWL library */

/*lint -esym(765,Cpu_Interrupt) Disable MISRA rule (8.10) checking for symbols (Cpu_Interrupt). */

void __init_hardware(void)

{

  /*** !!! Here you can place your own code before PE initialization using property "User code before PE initialization" on the build options tab. !!! ***/

  /*** ### MK60FX512VLQ15 "Cpu" init code ... ***/

  /*** PE initialization code after reset ***/

  SCB_VTOR = (uint32_t)(&__vect_table); /* Set the interrupt vector table position */

  /* Disable the WDOG module */

  /* WDOG_UNLOCK: WDOGUNLOCK=0xC520 */

  WDOG_UNLOCK = WDOG_UNLOCK_WDOGUNLOCK(0xC520); /* Key 1 */               <--- never gets past here

  /* WDOG_UNLOCK: WDOGUNLOCK=0xD928 */

  WDOG_UNLOCK = WDOG_UNLOCK_WDOGUNLOCK(0xD928); /* Key 2 */

 

 

 

 

And the ISR it jumps to is:

PE_ISR(Cpu_ivINT_Hard_Fault)

{

  /* This code can be changed using the CPU bean property "Build Options / Unhandled int code" */

  /* asm (HALT) */

}

 

 

It never gets to main.

I have another project (a native Keil project) that does get past this point...I just don't know why this ISR keeps tripping....nothing has been done on the processor yet.  I can't even get to the CLK config before it halts using Processor Expert.  I can't use my native Keil project because I want to use the LDD drivers from Processor Expert.
