What's the revision of the i.MX6Q on your board? Mine is 1.5 (TO 1.3)
Mine is a mx6solo rev1.1.
Could it be dependent upon SMP? Do you have an i.MX6Q board around to
try?
Unfortunately the only hardware I can test RS485 is based on mx6solo.

Adding Tim Harvey, who could probably test RS485 on MX6Q.
