[Buildroot] raspberry pi 3 hifiberry dac+ hat not working

Thu Aug 11 13:52:40 UTC 2016

Hi,

I’m having trouble getting a hifiberry dac+ to work on my RPI3 buildroot.

The system otherwise boots fine, and allows me to log in via dropbear. However e.g. the pcm512x i2c module doesn’t grab (as it should according to hifi-berry developers) the $4d address on the i2c-bus. Also, no ALSA-cards are being found.

I found one clear bug which I hope to add as pull-request to the buildroot-repo where the VFAT-boot-partition doesn’t contain the overlays/*.dtbo-files necessary to work with the config.txt dtoverlay=hifiberry-dacplus to be executed. Once that was fixed though, I’m out of ideas to what the problem could be.

Any suggestions on how to tackle this are welcome. The output of various relevant commands follows below.

Cheers,

Diez
