DEVKIT-MPC5744P CAN Connections

I'm having trouble with making the physical connections for CAN communication on the DEVKIT-MPC5744P board. Let's say CAN Bus 0 is transmitting and CAN Bus 1 is receiving a message. I have set CAN Bus 0 Receive Pin to B1 and Transmit to B0. Similarly CAN Bus 1 has A15 for receive and A14 for transmit. Which jumper connections should I make to enable data transfer between these two modules ? Where should I connect the CAN0H and CAN0L pins ? I don't see any high or low pins for CAN1, only receive and transmit.

Hello,

I checked MPC5744P devkit and unfortunately, it is not possible to interconnect two CAN modules, because there is only one CAN transceiver.

Also, CAN0 pins are not routed to external connector, so it is not possible to connect it with CAN1 pins. Only possibility is interconnect two boards together.

Sorry for any inconvenience.

Regards,

Martin
