STM32H743 does not receive 29Bit-IDs on CAN

[GS1]

Hello all,

I have an issue with receiving CAN Ids with 29 Bit IDs. 11 Bit IDs are working properly, but 29 Bit IDs are not received.

I do not use any filter setting, and in the GlobalFilter Setting I define to receive 29Bit IDs in FIFO0 or FIFO1 (desn't make a difference, Messages are not received with both settings).

Is there anything else which has to be activated to receive 29 Bit IDs?

Any ideas?

Here is my configuration:

...

   halErr = HAL_FDCAN_Stop(phCan);   // Stop CAN

   if (sCanBusInit[nCan].bFDCAN != TRUE)

      phCan->Init.FrameFormat = FDCAN_FRAME_CLASSIC;

   else phCan->Init.FrameFormat = FDCAN_FRAME_FD_BRS;

   if (sCanBusInit[nCan].nOperationMode != CAN_MODE_NORMAL)

   {

      phCan->Init.Mode = (uint32_t)sCanBusInit[nCan].nOperationMode;      // Loop Intern/Extern or Listen only

   }

   else

   {

      phCan->Init.Mode = FDCAN_MODE_NORMAL;

      CLEAR_BIT(phCan->Instance->CCCR, FDCAN_CCCR_TEST);

   halErr = HAL_FDCAN_Init(phCan);

   if (halErr != HAL_OK)

   {

      MyErrorHandler(E_CAN_DIV, halErr);

   }

   // Receive all IDs: 11-Bit in FIFO0, 29 Bit in FIFO1
