CAN-Bus Shield + Arduino M0 Pro = not working

Hello everyone,

i have a question, maybe some1 can help me.
I have used Arduino Uno with CAN-Vus Shield, and it worked perfectly.
I have bought Arduino M0 Pro board and after the same code(as on Uno) uploaded to the M0 Pro i get the message “CAN Init Failed”

Can someone help me with it?

Appreciate your help
