Hello everybody,
I am currently trying to figure out how to connect to McASP-capable TI-Audio-Codecs to the AM335x (BeagleBone Black). I understand that in theory the McASP should be capable of doing the necessary time division multiplexing on the McASP-Bus and that I have also to connect the SPI to both of the devices (with seperate enable-lines). I also have first experiences with the device tree overlays, where there is an entry to select the appropriate time-slots for each codec. But I do not know, if I have to modify any drivers.
My questions are:
1) Is there any example alerady implemented somewhere of what I try to do?
2) Can it even be done?
3) Any good starting points to get more information on the topic? Especially the driver part.
4) Are there other solutions? I.e. using McASP0 and McASP1? How to start here?
I truly would appreciate any glimps of information. My google search so far revealed little information. Also in this forum I saw only few information (forgive me, if I missed something out).
Best regards,
Markus
