Thanks so much. I downloaded the Debian 9.9 IoT image from beaglebone's web site, was able to get the OS to boot up, and i changed the uEnv.txt file, then rebooted, but the device driver did not load.
debian@beaglebone:/$ cat /proc/asound/devices
33: : timer
Are you sure the BB-BONE-AUDI-02-00A0 will work with the pocket beagle? I'm thinking it wont load because the compatible string does not contain PB, right?
compatible = "ti,beaglebone", "ti,beaglebone-black", "ti,beaglebone-green";
Also, i'm not sure if the pinmux would be the same on these devices vs PB.
Thanks for the help!
