SAMA5D27 POWER ON & WKUP buttons

Tue Sep 17, 2019 5:33 pm

Hello.

I am using SAMA5D27-SOM1-EK1 Board.

I noticed that there are, instead of NRST BUTTON which i use to reset the card and USER button, 2 other buttons named POWER ON and WKUP.

But i did not find the use of them and they are not related to any GPIO PIN unlikely USER button which is connected to GPIO PA29.

I just want to use one of these 2 buttons as gpio. How can I do that ? Thanks

You can't.
Study the schematics (or section 3.2.4, Push Button Switches) in the board' s User Guide.
