Can interface for Pre transmit callback

[karthikravi]

Team,

I am using MPC57xx with S32 design studio.  Need to know whether FlexCAN supports PreTransmit callback ?  if so what is the interface?

If it doesn't support, provide a suggestion how to inject CRC error during transmit.

Hi,

the MB interrupt (and so respective callback), if enabled, is called upon successful reception of the message into the MB or after successful transmission of the message without error. So no pre transmit callback can be possible.

There is no option to inject CRC error within FlexCAN module, you can e.g. purchase a commercial CAN development tool. Some can controllably inject errors.

@PetrS you mentioned about commercial CAN development tool, can you provide any example?  I assumed you mean CAN stacks which supports CRC error injection.  please confirm

Hi,

I meant CAN tools like Vector's CANoe, PCAN View etc.
