CCS: Problem on reception message with DCAN

Tool/software: Code Composer Studio

Hello,

I am learning how to use the CAN of the TMS570 LS 12,I try to send a message from CAN1 to CAN 2 however, I can not get the message (the program is locked at: while(!canIsRxMessageArrived(canREG1,canMESSAGE_BOX2)); ) and  I can not figure out why it does not work.

Here is my code:

void main(void)
{
/* USER CODE BEGIN (3) */
	gioInit();
	canInit();


	unsigned char tx_data[8] = {'G','E','I','I','M','O','N','T'};
	unsigned char rx_donnee[8] = {};
	int n = 0;
	int i = 0;


		canEnableloopback(canREG1,Internal_Lbk);
		canTransmit(canREG1,canMESSAGE_BOX1,tx_data);

		while(!canIsRxMessageArrived(canREG1,canMESSAGE_BOX2));



		canGetData(canREG1,canMESSAGE_BOX2,rx_donnee);
		for (i=0;i<=8;i++);
		{
			if(tx_data[i]!=rx_donnee[i])
			{
				n = 1;
			}


		}


		if(n==0)
		{
			gioToggleBit(gioPORTB, 1);
		}

		while (1);
	//xTaskCreate(firstTask, "task1", 128, 0, 2, 0);
	//vTaskStartScheduler();



	/* USER CODE END */
}

And here is my configuration of HALCOGEN:

This is the first time I use this type of microcontroller and I do not understand why it does not work.

Does  Someone can help me ?

Regards.
