MPC5644A CAN_B Pin Connections

tgc-yilmaz — Tue, 09 Jun 2020 11:49:09 GMT

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?

Thank you for your help...

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.

Hello,

By providing this connection, I was able to work with the 324 pin microcontroller, but when I provided the same connection on the 176 pin microcontroller, I could not observe the messages. Could you please help with this issue, or if there is a document where I can see the pin separation for 176 and 324 pin evaluation boards, can you guide me?

Thanks in advance.
