Hi All,
Attached image is my setup for CAN communication using DEVkit MPC5748G.
I am trying CAN receive example code (flexcan_receive_Z0_4) in S32DS.
But code is not working. So for more diagnosis I traced CAN signal using DSO.
I have observed CAN high and Low signal on CAN_H and CAN_L.
But there is no signal found on Rx pin (Between transceiver IC and MPC5748G controller).
My set up is working for transmit example code ( flexcan_transmit_Z0_4) .
Please help me to sort out this problem.
Hello,
This seems to be a similar issue to the one in thread https://community.nxp.com/message/1025113 .
Try adding a 120 ohm resistor between CAN_H and CAN_L.
Hope it helps,
Mike
