Test CANPS on two ZC7020 Boards (as transciever and reciever)

Jump to solution

Hallo Experts,

I try to interface CAN (J52) using CANPS on ZC7020 Boards. As mentioned in subject. i used two boards here.

1.I saw some tutorials and some advice in internet until i can test one board using loopbacak mode as mentioned in https://xilinx-wiki.atlassian.net/wiki/spaces/A/pages/18842496/Linux+CAN+driver
i have the same expected output.
2. now i try to wire the CAN_L and CAN_H to two zc7020 Boards with 120 Ohm resistor.

3. i boot my first petalinux project in terminal and use cansend can0 command to send the data https://sgframework.readthedocs.io/en/latest/cantutorial.html

4. i boot my sec petalinux project (same design) in another terminal and use candump can0 command to reicieve the data but nothing came.
note: i use the same bitrate 500000 to sample the can.

after wiring.pngcandump can=.png
any suggest?
