So finally tonight I managed to connect up the Audioinjector to the correct pins on the Orangepi PC2.
It seems to be talking over i2c to the wm8731 OK, but fails to setup using DMAEngine? Here's the relevant parts of dmesg: [ 0.000000] Linux version 4.15.0-rc2-gbd0835a69-dirty (chris@sunxi-build) > (gcc version 7.2.0 (Debian 7.2.0-11)) #5 SMP PREEMPT Mon Dec 11 18:35:03 > GMT 2017 > [ 0.000000] Machine model: Xunlong Orange Pi PC 2 > [ 2.001533] ALSA device list: > [ 2.004504] No soundcards found. > [ 7.954144] sun4i-i2s 1c22000.i2s: Could not register PCM > [ 7.972456] sun4i-codec 1c22c00.codec: Failed to register against > DMAEngine > [ 8.000740] wm8731 0-001a: Assuming static MCLK > [ 8.005336] wm8731 0-001a: 0-001a supply AVDD not found, using dummy > regulator > [ 8.012660] wm8731 0-001a: 0-001a supply HPVDD not found, using dummy > regulator > [ 8.020087] wm8731 0-001a: 0-001a supply DCVDD not found, using dummy > regulator > [ 8.020157] sun4i-i2s 1c22000.i2s: Could not register PCM > [ 8.021684] sun4i-codec 1c22c00.codec: Failed to register against > DMAEngine > [ 8.039901] wm8731 0-001a: 0-001a supply DBVDD not found, using dummy > regulator > [ 8.051789] sun4i-i2s 1c22000.i2s: Could not register PCM > [ 8.059306] sun4i-codec 1c22c00.codec: Failed to register against > DMAEngine > [ 8.697652] sun4i-i2s 1c22000.i2s: Could not register PCM > [ 8.708108] sun4i-codec 1c22c00.codec: Failed to register against > DMAEngine > [ 8.718261] sun4i-i2s 1c22000.i2s: Could not register PCM On 12 December 2017 at 06:23, Code Kipper <[email protected]> wrote: > I don't understand why they changed the header on the newer boards > away from something that was raspberry pi compatible, the only thing > in common now is that they are 40 pins.
