I'm having trouble with config-pin:

$ *config-pin -a P9_30 spi # Data out*
$ *config-pin -a P9_31 spi # Clock*
P9_31 pinmux file not found!
P9_31 overlay not found
Loading cape-universala overlay
bash: line 0: echo: write error: File exists
Error loading device tree overlay file: cape-universala

P9_30 configures but P9_31 doesn't.  I'm running as debian.


Don't use the -a option, the overlay is setup to auto load.

Those pins are the audio side of HDMI..

Add this to /boot/uEnv.txt

disable_uboot_overlay_audio=1

And reboot.
