Hello,

 

I am using mpc5644a. I want to communicate over the CAN_B. EVB document provides information about the pin connections required for CAN A and CAN C, but information about FlexCAN B is unfortunately not available. What are the pin connections required to communicate over CAN_B? Can you help with this?

Hi,

remove jumpers on J27 and use wires to connect CAN_B RX to J27.3 and CAN_B TX to J27.4.

Hello,

Thank you for your answer. But I'll have another request. Can you specify the CAN_B RX and CAN_B TX pins in detail? Unfortunately, despite my research, I could not obtain this information. It is specified for CAN_A and CAN_B but CAN_B is not available.

Hi,

you should find where CAN_B signals are located on EVB. As per xPC564A EVB User Manual it is on PJ11

then connect those pins to J27. CNRXB to J27.3 and CNTXB to J27.4.
