Hey hi Graham, Its an elaborate and very well explained post. I wanted to use same CODEC to play an audio on BBB but on the latest Debian version 9.3. Device tree overlay structure is very different in the latest images. Will these same commands work on recent images as well? If you have tried i

I'm also interested as I have a project where I will interface directly to the I2S/McASP interface. Did you figure it out? On Tuesday, January 3, 2017 at 8:57:29 AM UTC-8, Graham wrote: > > I spent most of the weekend down in the rabbit-hole, trying to get a > CircuitCo Rev_B Audio cape to work,

Yes, I was able to get a CircuitCo Rev.B Audio cape running, using the I2S/McASP interface. I'll write it up for you, if you are interested. If you are going to use a different CODEC or other device on the I2S/McASP interface, you will need to see if a driver already exists for it, or if it fits

I would appreciate the writeup, thank you. My project requires interfacing to an IC with I2S input. I planned on using (something like) aplay to write audio out to I2S/McASP channel (using built-in driver support) and hoped I could also use the built-in support (drivers) for SPI and/or I2C usin

It will be a day or so, but I will post the write-up here. You will not be able to control the IC independently, since the kernel claims the device. The Linux audio system expects to be able to control the audio controls such as volume, etc. by reaching into the CODEC through the control bus. T

This is very old, but I'm still interested in using I2S to directly drive an audio device (software defined radio module). Could you post your write-up if available? Thanks. On Tuesday, May 16, 2017 at 11:21:30 AM UTC-7, Graham wrote: > > It will be a day or so, but I will post the write-up here.

@Graham thanks for posting this. I expect to have to do some things differently since my target CODEC is different and overlays are now handled differently. In any case, this will give me a good head start and foundation to build on. On Tuesday, December 26, 2017 at 12:54:04 PM UTC-8, Graham wr
