Hello, giuliomoro!
Thanks again for all of your help.
I copied the dtbo file as you instructed.
Running:
echo bspm_P9_15_27 > /sys/devices/bone_capemgr.?/slots
causes the analog inputs to work as expected.
I also modified /etc/init.d/bela as instructed and confirmed that it saved correctly.
However, for some reason the analog inputs no longer work after a reboot. It seems to just skip over the three extra lines added to the init file.
After a fresh reboot, the output from dmesg ends at:
[ 16.359945] bone-capemgr bone_capemgr.9: slot #9: dtbo 'BB-BONE-BAREAUDI-00A0.dtbo' loaded; converting to live tree
[ 16.371244] bone-capemgr bone_capemgr.9: slot #9: #2 overlays
[ 16.378299] bone-capemgr bone_capemgr.9: slot #9: Applied #2 overlays.
Then, attempting to run a patch in the Bela IDE that uses analog inputs adds the following:
[ 51.937995] gpio_request: gpio-48 (sysfs) status -16
[ 51.938013] export_store: status -16
[ 51.951994] gpio_request: gpio-115 (sysfs) status -16
[ 51.952011] export_store: status -16
Finally, manually running:
echo bspm_P9_15_27 > /sys/devices/bone_capemgr.?/slots
again makes the analog inputs work again and adds this to the dmesg output:
