I want to know if it's possible to load BB-BONE-AUDI-02 via /boot/uEnv.txt
and watch digital output on oscilloscope without plug in cape.
I try it (also loading am335x-boneblack-audio.dtb of course), all kernel
messages (dmesg) are ok (except i2c register setup, of course, cape isn't
plugged), when I play a wave file with aplay, all seems ok but nothing move
on digital audio pin. I use last debian release : Debian 8.5 2016-05-13 4GB
Something strange, removing am335x-boneblack-audio.dtb from uEnv.txt give
many kernel error message but soundcard is here (aplay -l) and playing a
wave file give signal on oscilloscope. However only dsp_a or dsp_b digital
audio format are working and I need I2S, right_J or left_J....
Do I need to do a kernel update?
