The Flock unit is a digitally controlled unit but the audio signal path is completely analog.

unfortunately, there is no porting guide available. We discuss currently the introduction of a new build system. If it is not very urgent, then I would wait a bit with the porting.<br class="">

You can also start right now and use the stm32f4 BSP as an example. The relevant directories are:<br class="">
