Compiler/TMS320F280025C: the main function code will jump to abort() function when initialize big array

Tool/software: TI C/C++ Compiler

Hi Expert,

I use the example code from the below link, define a big array as below:

C:\ti\c2000\C2000Ware_MotorControl_SDK_F28002x_3_00_00_01\solutions\drv8312_c2_kit\f28002x\ccs\sensorless_foc

uint16_t array[4096];

and initialize the array after the function HAL_enableDebugInt();//

// enable debug interrupts

//

HAL_enableDebugInt(halHandle);

for(i=0;i<4096;i++)

{

array[i] =i;

}

After run the code, there will have a strange issue, that is the code will run to abort() function as below showed, but the code also can run to

mainISR interrupt.

void abort(void)

{

/*-------------------------------------------------------------------*/

/* SET C$$EXIT LABEL SO THE DEBUGGER KNOWS WHEN THE C++ PROGRAM HAS */

/* COMPLETED. THIS CAN BE REMOVED IF THE DEBUGGER IS NOT USED. */

/*-------------------------------------------------------------------*/

__asm(" .global C$$EXIT");

__asm("C$$EXIT: nop");

for (;;); /* SPINS FOREVER */

}

If I modify the code below, then everything is ok.

for(i=0;i<100;i++)

{

array[i] =i;

}

I compare the memory map between the changed code and original code, it seems there are the same.

I post the code attached so that the issue can be reproduced, could you help take a look at what is the reason?
