I've checked some manuals and found a bit in flexcan register MCR where you can disable hardware loopback. But now I'm wondering which flexcan device support this bit. At least flexcan on Coldfire 5484 (yeah a pretty old one) doesn't do it. Does somebody else know which devices have / have not this bit?
