TMS570LC4357: TMS570LC43

Hello everybody,

I have some issues with my TMS570LC43-board.

I have implemented a pretty simple code to test the can communication. I enabled the loopback functionality and tried to update the ID with the generated halgogen function "canUpdateID()".

The problem is, after a successfully Update of the messageID, i can't receive any message.

On the other hand, i received normally the messages, if a don't use "canUpdateID()".and preconfigure the MessageID with halgogen.

I configured the messageboxes with halgogen like:

messagebox[1 - 8] are Tx-messageboxes with respectively messageID 1 - 8 

messagebox[9 - 16] are Rx-messageboxes with respectively messageID 9 - 16 

i tried with my code to modify the messageIDs of the first 4 Rx-messageboxes, in order to receive the messages.

Below my code

     uint8 i;
     uint32 ID;
     uint8 data[4][8];
     uint8 Data[8] = {1,2,3,93,5,6,7,8};
     uint8 Data2[8] = {8,7,4,93,3,2,1,0};
     uint8 DataArray[4][8];
     uint32 ResultOfTransmission;

     canInit();
     canEnableloopback(canREG1, Internal_Lbk);
     memcpy(&DataArray[0][0], Data, 8);
     memcpy(&DataArray[1][0], Data2, 8);
     memcpy(&DataArray[2][0], Data, 8);
     memcpy(&DataArray[3][0], Data2, 8);
     for (i = 1; i<= 4; i++){
         ResultOfTransmission = canTransmit(canREG1, i, DataArray[i-1]);
         canUpdateID(canREG1, i + 8, i);
     }
    while(1){
       static UINT32 j = 1;
       printf("**** Round nr %d*******\n", j);
       if(j > 8){
           if (canIsMessageBoxValid(canREG1, j )){
               ID = canGetID(canREG1, j );
                if (canIsRxMessageArrived(canREG1, j )){
                    static a = 0;
                    if (a < 4){
                        ResultOfTransmission = canGetData(canREG1, j + 8, &data[a][0]);
                    }
                   a++;
               }   /* kein else nötig */
           } /* kein else nötig */
       }
       j++;
  }
