CPU:IMX6Q

I want to design a bare board can driver, but something goes wrong, and I don't know how to  solve it:

When I loopback CAN1 and CAN2 everything is right!

But when I disconnect them ,there are bus errors all the time !

And I can't send or receive any data from other board.

I'm sure the baud rate is right, and the pins are right.

How to config flexcan's registers?

I copy from Linux.

Thx~~~~~~~~~~~~~~~~~
