Differences between Orange Pi+2 and Pi+2E in fex'es

AlexNT

Hello, guys!
Can anyone clarify, what are the main differences between Orange Pi Plus 2 and Orange Pi Plus/Plus 2E in terms of hardware description in a fex file?
What if I use an Plus/Plus 2E fex on my Orange Pi Plus 2? What will NOT work? Or the fex'es of Orange Pi Plus 2 and Orange Pi Plus 2E are the same? Or what should I add/modify to write the fex for Orange Pi Plus 2?
