Pi3 & Zero W : overlays with buildroot

Thu Dec 07, 2017 3:39 am

Hey all,

It is possible to compile buildroot however it appears that overlays aren't working ...
Anyone got pointers on using overlays with buildroot and the Pi3/zero W ?

thanks

Hey Flatmax,
Did you ever get this working?

I have buildroot and overlays working using this branch: http://www.jumpnowtek.com/rpi/Raspberry ... droot.html

And it loads your audio injector cards and everything but I am getting no audio...

Need to mess with the mixer some...

Anyways.. Did you ever get your sound card working with buildroot?

Actually it looks like my hardware is not working with the Raspbian build either. I have another Pi Zero W and Audio Injector I will try again on later today.

I only connected one ground from the audio card to my pi so I think that may be in issue. Anyways, I am hell bent on getting buildroot and this all working so I will report back later today or tomorrow on my progress...

YES!

It was my hardware, swapped out with different Pi Zero W and audio injector zero and audio is working fine with buildroot!

I will post some more on your forum!
