I can't see why P1.00 doesn't work the way I expect on the nrf5340dk...
This is just the blinky sample used to confirm my boards overlay file. Blinky works on all the pins except &led0(P1.00).
P1.00 seems to be unencumbered by any other peripheral so I'm not sure why this one doesn't work.
I am most interested in "where do I go to find out why something like this doesn't work". Or am I just missing something obvious?
This is what I was referencing: https://infocenter.nordicsemi.com/index.jsp?topic=%2Fug_nrf5340_dk%2FUG%2Fdk%2Fintro.html
