I have a project that will use the same processor of the beaglebone black, so I`ve decided to use this board to build a prototype. The kernel from my beaglebone black is 3.8.13-bone47 and I am using a BlueGiga board to send I2S (using 3 wires) audio to the beaglebone. My goal is to make the beaglebone receive I2S (maybe using arecord - alsa), compress the audio using opus enconder and send it to a web browser. At this moment, I am able to receive a audio from a web radio in wav format (I need to change that to audio receive from BlueGiga), encode the audio to opus format and send to a web browser (I create a server that runs inside the beaglebone). However, I am having a lot of difficulties to turn the beaglebone able to receive I2S. I am trying to use the device tree overlay but without success. I disable the HDMI in the Uenv.txt and I am able to achieve the new overlay (I check the slots and the pins modes). However, I can`t use arecord because alsa do not recognize the audio coming from the bluegiga using wires. My dts file is:</span></p><p style="margin:0;">/dts-v1/;</p><p style="margin:0;">/plugin/;</p><p style="margin:0;">/ {</p><p style="margin:0;">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; compatible = &quot;ti,beaglebone&quot;, &quot;ti,beaglebone-black&quot;;</p><p style="margin:0;">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
