How to correctly set up FDCAN Message RAM Start Addresses?

How do I have to set the configuration of the FDCAN Message RAM Start Adresses correctly in order to use 2 CANFDs simultaneously?

Is there an example which shows a correct initialisation? The default samples initialize all start Adresses to 0, but this leads to Message corruption!

Here my sample code:

Would this be correct?

   if (nCan == CAN0)

   {

      phCan->Instance = FDCAN1;

      uCANOffset = 0;

   }

   else

   {

      phCan->Instance = FDCAN2;

      uCANOffset = 1024;

   }

   phCan->msgRam.StandardFilterSA = 0;

   phCan->msgRam.ExtendedFilterSA = 0;

   // Start-Adressen für Message-RAM:

   phCan->msgRam.RxFIFO0SA = 0+uCANOffset;

   phCan->msgRam.RxFIFO1SA = 512+ uCANOffset;

   phCan->msgRam.RxBufferSA = 1024;

   phCan->msgRam.TxEventFIFOSA = 0;

   phCan->msgRam.TxBufferSA = 0;

   phCan->msgRam.TxFIFOQSA = 0;

   phCan->msgRam.TTMemorySA = 0;

   phCan->msgRam.EndAddress =0;

   phCan->ErrorCode = 0;

Thank you for any help.
