Hi Forum,
I am attempting to create a device overaly to turn off the USR0-3 on Ubuntu
13.10 (Linux ubuntu-armhf 3.8.13-bone30) on my Beagle Bone Black A5C.
I have performed the following process - but the USR0-3 LEDs continue to
flash. I expected all of them to turn off and have trigger state of
"[none]"
The DTS (BBB-LEDS-00A0.dts) file I have created is as follows
/dts-v1/;
/plugin/;
/
{
compatible = "ti,beaglebone", "ti,beaglebone-black";
part-number = "BBB-LEDS-00A0";
version = "00A0";
fragment@0
{
target = <&ocp>;
__overlay__
{
gpio-leds {
compatible = "gpio-leds";
pinctrl-names = "default";
pinctrl-0 = <&userled_pins>;
led0 {
label = "beaglebone:green:usr0";
gpios = <&gpio2 0x15 0x0>;
linux,default-trigger = "none";
default-state = "off";
};
led1 {
label = "beaglebone:green:usr0";
gpios = <&gpio2 0x16 0x0>;
linux,default-trigger = "none";
default-state = "off";
};
led2 {
label = "beaglebone:green:usr0";
gpios = <&gpio2 0x17 0x0>;
linux,default-trigger = "none";
default-state = "off";
};
led3 {
label = "beaglebone:green:usr0";
gpios = <&gpio2 0x18 0x0>;
linux,default-trigger = "none";
default-state = "off";
};
};
};
};
};
I have the latest dtc with the patches from Robert Nelson ( wget -c
https://raw.github.com/RobertCNelson/tools/master/pkgs/dtc.sh)
I compile the DTS file using
dtc -O dtb -o BBB-LEDS-00A0.dtbo -b 0 -@ BBB-LEDS-00A0.dts
Copy the generated dtbo file to /lib/firmware
sudo cp BBB-LEDS-00A0.dtbo /lib/firmware/
Load the device tree overlay using
sudo sh -c "echo BBB-LEDS > /sys/devices/bone_capemgr.9/slots"
I see the slots that the "cape" is loaded

Could someone point me as towards what I have done wrong?
