Aw so, I don't know if this is a good place to put this, I mean, I won't hold it against the mods for deleting it, but I just wanted to point out that the pin map in the kl82 FRDM board QUICK START GUIDE is incorrect. It's obvious if you look for the duplicates, but this made me get my probes out for a couple hours this morning :-(.

Hi Andrew
I checked pin out documentation in FRDM board QUICK START GUIDE, I don't see any problem in it, it in concordance with SCH REV B2.
For your reference, you could download schematic designs in the software and tool tab of the frdm board page: Freedom Development Board for Kinetis KL82|NXP

Hi Andrew Pikul
OK, I can see the problem, pin 8 and pin 6 are actually PTD7 and PTC1. Number pin for this are changed, Thanks for pointing this out, I will share your comments to fix it as soon as possible.
As I comment, please check FRDM schematic design, there is not error in it.
Best Regards

Check pin 15 on the unpopulated flexio header too.
