Can the parallel port 1 be used on the iMX6 Dual-Lite (& solo)
Most of the documentation shows that the IPU can accept both Parallel Port #0 & Parallel Port #1
(e.g. IMX6SDLRM rev 2)
However, AN4397 (Common Hardware Design for i.MX 6Dual/6Quad and i.MX 6Solo/6DualLite) Rev 1, contains the rather worrying note:
Do not use Parallel 1 port as the video input when migrating an
i.MX 6Dual/6Quad hardware design to the i.MX 6Solo/6DualLite."
(In Chapter 8 Video input requirements for migration)
So, what is the reason for this?
If parallel port 1 cannot be used, then why is it mentioned in all the other documentation?
