Problem with Rev B

I have been using dcan1 the Beaglebone Black Rev A6A. However, I just received a new BBB Rev B and followed the same device tree config as the other version and I am not getting any output on the rx and tx lines. Has anyone else had a similar problem between versions?

I am using Anstrom 3.8

The Rev B has an AM3358 processor. That is the only difference between the two revisions. You may want to check the eratta for the processor and see if there was any impact when moving to the new die versus the old die used in the AM3359.
