Hi.

How to install/build the correct version of wiringPi on M2U? I need to get access to gpio’s but all the versions I’ve tried can’t be compiled and the built-in (Raspbian version) is not working too.

Please help!

are you see here :

or what image are you used . our image have support wiringpi defaults:

If you look closer to WiringPi source code, you can see it receive info about board from:

/var/lib/bananapi/board.sh

The easiest solution (not saying it is the right one) is to create it with this content (copied from bananapi images):

BOARD=bpi-m2u
BOARD_AUTO=bpi-m2u
BOARD_OLD=bpi-m3

Tested on Armbian image.

It is correct I created the folder and the file in the aforementioned route added the previous parameters and now it works without problems. Thank you very much for your help, do not even reach to see the source code

Hello,

I hope someone can help me. I would like to use GPIO24 and GPIO25 for output, but something prevents them to be used as such, only as input. I assume that these GPIO pins are used by the camera driver. Is it possible somehow to “regain” these pins if the camera is not used?

Thanks,
