TMS320F28P650DK: an error occured: failed to parse the previous frame FP

Part Number: TMS320F28P650DK
Other Parts Discussed in Thread: C2000WARE

Hi,
I'm using a launchpad TMS320F28P650DK9 and ccs 12.6. Got the error: " _system_post_cinit() 0x3FFE7A (an error occured: failed to parse the previous frame FP)" while debugging the code below.
linked to my project is the "f28p65x_codestartbranch.asm" source file and I've tried using both the "28p65x_generic_flash_lnk_cpu1.cmd" and the "28p65xdkx_generic_flash_lnk_cpu1.cmd" linker command files. it might be important to note that I don't have a f28p65x_lnk.c file linked to the project (not sure if its relevant). Any help on the subject would be much appreciated. Thanks.

code:

#include "F28x_Project.h"
#define BLINKEY_LED_GPIO 31

void main(void)
{
      //InitSysCtrl();
      InitGpio();
      GPIO_SetupPinMux(BLINKEY_LED_GPIO, GPIO_MUX_CPU1, 0);
      GPIO_SetupPinOptions(BLINKEY_LED_GPIO, GPIO_OUTPUT, GPIO_PUSHPULL);

      while(1)

      {
             GPIO_WritePin(BLINKEY_LED_GPIO,0);
             DELAY_US(1000*500);
             GPIO_WritePin(BLINKEY_LED_GPIO,1);
             DELAY_US(1000*500);
      }
}
