Re: sBIT USB boot
Are you sure you can do I2S through some GPIO pins? Otherwise it would not work as Pi replacement for the sBitx.

Hi Dave,
There are some old CFLAGS. I made a fork and fixed the Makefile to have sane intel and arm parameters:

Might the update I did for the headset issue (/g/BITX20/message/108643) provide the solution for this too?
