Hi Moses,
The LEDs are reserved in the following file: <linux_dir>/arch/arm/boot/dts/am335x-bone-common.dtsi:
[quote] leds {
pinctrl-names = "default", "sleep";
pinctrl-0 = <&user_leds_default>;
pinctrl-1 = <&user_leds_sleep>;
compatible = "gpio-leds";
led@2 {
label = "beaglebone:green:heartbeat";
gpios = <&gpio1 21 GPIO_ACTIVE_HIGH>;
linux,default-trigger = "heartbeat";
default-state = "off";
};
led@3 {
label = "beaglebone:green:mmc0";
gpios = <&gpio1 22 GPIO_ACTIVE_HIGH>;
linux,default-trigger = "mmc0";
default-state = "off";
};
led@4 {
label = "beaglebone:green:usr2";
gpios = <&gpio1 23 GPIO_ACTIVE_HIGH>;
linux,default-trigger = "cpu0";
default-state = "off";
};
led@5 {
label = "beaglebone:green:usr3";
gpios = <&gpio1 24 GPIO_ACTIVE_HIGH>;
linux,default-trigger = "mmc1";

};
};[/quote]
Best regards,
