I don't have an Audio Cape (everywhere is out of stock) but I just want to test the set up as if I did.
I ran all steps as given by the instructions (http://elinux.org/CircuitCo:Audio_Cape_RevB) including installing a new DT overlay, disabling HDMI and adding to the slots file. Then I try speaker-test -D default:EVM and put an oscilloscope on pin P9_28. No waveform comes out. This should be the I2S serial output, but it's just a flat line. I have no idea how to debug this. Any suggestions? -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
