Hello everybody,

I am interested in CAN bus communication with iMX6 Rex.

I have read that the SD3 card interface shares its pins with the CAN bus interface.
Is it right that it is possible to connect the RX/TX pins of a CAN transceiver with the iMX6?
Unfortunately I have no idea which pins of the base board must be connected with the CAN transceiver.

I want to use MCP2551 CAN transceiver which has the following ports:

  1. TX
  2. GND
  3. VDD
  4. RX
  5. VREF
  6. CAN_L
  7. CAN_H
  8. RS (Slope Resistor Input)

GND, VDD, CAN_L and CAN_H are clear to me.

Could you please tell me to what pins I have to connect TX, RX, VREF and RS?
Will the SD card interface and the CAN bus interface work simultaneosly?
Is it possible to connect two CAN bus transceivers at the same time?

Thanks for your help! :)
