Hi,

I finished the led (A,B,C) like APM boards.

I'm attaching the DTS for Buzzer and LED's.

Software

To compile you must use

dtc -O dtb -o /lib/firmware/BBBMINI-BUZLED-00A0.dtbo -b 0 -@ BBBMINI-BUZLED.dts

and load the DTS before arducopter(in my case I'm using inside rc.local).

echo BBBMINI-BUZLED > /sys/devices/platform/bone_capemgr/slots

Hardware

3 leds

3 resistors - 470 Ohms

connected to pins P8.9   - Led A

connected to pins P8.10 - Led B

connected to pins P8.11 - Led C

Led behaviors(get from http://ardupilot.org/copter/docs/common-apm-board-leds.html):

Led A

Solid = armed, motors will spin when throttle raisedSingle Blink = disarmed, motors will not spinDouble Blink = disarmed, motors will not spin, cannot arm because of failure in pre-arm checks1

Led B

Only flashes along with A and B during calibration or as part of the in-flight auto trim feature.

Led C

Solid = GPS working, 3D lock

Blinking = GPS working, no Lock

OFF = GPS not attached or not working

I'm creating the PR today and will update here when available at main repo.
