CCS: No wavefrom coming on CAN Bus Debug Error: _c_int00() at boot.asm:227 0x00000C5A(_c_int00 does not contain frame information)

Tool/software: Code Composer Studio

Hi all,

I am working CAN module. Previously I created thread regarding CAN module issue: 

This issue was resolved and I was getting proper CAN frame at output. 

Further I added ADC code. After this modification my code was working and CAN frames coming out at PB1. 

Code is as follows

#include <stdint.h>
#include <stdbool.h>
#include "inc/hw_memmap.h"
#include "inc/hw_types.h"
#include "inc/hw_can.h"
#include "inc/hw_ints.h"
#include "driverlib/debug.h"
#include "driverlib/sysctl.h"
#include "driverlib/gpio.h"
#include "driverlib/adc.h"
#include "driverlib/can.h"
#include "driverlib/interrupt.h"
#include "driverlib/pin_map.h"
#include "driverlib/sysctl.h"

uint32_t ui32ACCavg1;
uint8_t Count=0;
uint32_t ui32SysClock=0;
volatile bool g_bErrFlag = 0;
volatile bool g_bTXFlag = 0;

void SimpleDelay(void)
{
    SysCtlDelay(40000);
}

void CANIntHandler(void)
{
    uint32_t ui32Status;
    ui32Status = CANIntStatus(CAN0_BASE, CAN_INT_STS_CAUSE);
   if(ui32Status == CAN_INT_INTID_STATUS)
    {
        ui32Status = CANStatusGet(CAN0_BASE, CAN_STS_CONTROL);
        g_bErrFlag = 1;
    }

    else if(ui32Status == 1)
    {
        CANIntClear(CAN0_BASE, 1);
        CANMessageClear(CAN0_BASE, 1);
        g_bErrFlag = 0;
        g_bTXFlag = 1;
    }
    else

    }
}

                Count=0;
                while(Count<10)
                {
                    while(!ADCIntStatus(ADC1_BASE, 3, false))
                    {
                    }
                    ADCSequenceDataGet(ADC1_BASE, 3,&ui32ACCValues1);
                    ADCIntClear(ADC1_BASE, 3);
                    ui32ACCavg1=ui32ACCavg1+ui32ACCValues1;
                    Count++;
                }
                ui32MsgData=ui32ACCavg1/10;
                CANMessageSet(CAN0_BASE, 1, &sCANMessage, MSG_OBJ_TYPE_TX);
                ui32ACCavg1=0;
                SimpleDelay();
            }

        }
}

Now same code is not working. No CAN frames are coming.

I have 4 spare board 2 in use and 2 new(box pack).

I tried to reprogram this 4 spare board with this code and simple TX code which I mention in my previous thread. Still i cant see CAN frames coming out.

PB1 pin is at 3.3V alwasys.

All boards are working as I reprogram with ADC code.I am getting proper output. 

LED blinking code is alo running. I tried to toggle PB0& PB1 pin and its working fine.I got square ware at output .

From the day, CAN is not working I get error at debugging as : c_int00() at boot.asm:227 0x00000C5A(_c_int00 does not contain frame information

Debug error and setting in CCS are in below pics:

Hope this issue will resolve soon
