I am using MPC5744P DEVKIT (Link)with 144LQFP micro.

I want to use the CAN to send and receive message.


Step 1

I changed the jumper setting of the DEVKIT to use 12V Power supply.


Step 2

Used the flexCAN master example project but on the oscilloscope, both high and low pins stay recessive.

I also used VECTOR CAN Tool to see if messages are being sent on the bus but there is nothing. Not even Error Frames. 


Step 3

I adapted the model (attached) where I used PIT to make sure messages are sent periodically. But still CAN high and Low are recessive. 


Please provide your input.
