Have you connected the two CAN connectors together (J1 and J2)? Connect J1-H to J2-H and J1-L to J2-L.

sir,
now i am try to transmit and receive the data with in the single DCAN1.
in DCAN1, i configure the message object 1, for transmit. and the message object 2, for receive.
i did not get the data. is there any other changes i want to do in hardware (or) software side.

my main prog code:

#include "system.h"
#include "esm.h"
#include "can.h"
uint8 tx_buffer[8]={'H','E','R','C','U','L','E','S'};
uint8 rx_buffer[8]={0};

void main(void)
{

canInit();

canTransmit(canREG1, canMESSAGE_BOX1, tx_buffer);

while(!canIsRxMessageArrived(canREG1, canMESSAGE_BOX2));
canGetData(canREG1, canMESSAGE_BOX2, rx_buffer);

}
