BRS bit not set for routed CAN FD messages

[ugandham]

I am able to route the messages from CAN to CAN FD but the BRS bit of my routed CAN to CAN FD messages are not set to 1.
Could you please help me with that?

If you want to send on the CAN-FD Bus Frames, that use BRS, you need to setup the Device with two differnet Bitrates (Nominal and Data)
For example

Code: Select all

// timings for CAN1 and CAN2
static const CANTiming_t  Timing_CANx[2] = {
_80M_500K_80____4M_80_ISO,	  // CAN1
_80M_500K_80____4M_80_ISO	  // CAN2
};
CAN_Initialize ( CAN_BUS1, &Timing_CANx[CAN_BUS1]);
CAN_Initialize ( CAN_BUS2, &Timing_CANx[CAN_BUS2]);

and set the MSG-Type Bit of the CAN Frame you want send, with the needed Flags (FD Frame Flag and Bit Rate Switch Flag):

Code: Select all

RxMsg.msgtype = CAN_MSGTYPE_FDF | CAN_MSGTYPE_BRS;
