HI Forum, I am attempting to create a device over lay for BBB "Linux beaglebone 3.8.13-bone70" that will disable the linux heartbeat LED.
I am interested to do this primary as a learning process for device tree, but I plan to use the BBB in a room where I don't want a LED to flash. I followed the guide at http://elinux.org/BeagleBone_and_the_3.8_Kernel. dtc -O dtb -o BBB-LEDS.dtbo -b 0 -@ BBB-LEDS-00A0.dts sudo cp BBB-LEDS.dtbo /lib/firmware/ sudo sh -c "echo BBB-LEDS > /sys/devices/bone_capemgr.9/slots" However the LED continues to flash. Could someone point me how to get the overlay to work? Thanks Joshua /dts-v1/; /plugin/; / { compatible = "ti,beaglebone", "ti,beaglebone-black"; part-number = "BBB-LEDS"; version = "00A0"; fragment@0 { target = <&am33xx_pinmux>; __overlay__ { userled_pins: pinmux_userled_pins { pinctrl-single,pins = < 0x54 0x7 /* gpmc_a5.gpio1_21, OUTPUT | MODE7 */ >; }; }; }; fragment@1 { target = <&ocp>; __overlay__ { gpio-leds { compatible = "gpio-leds"; pinctrl-names = "default"; pinctrl-0 = <&userled_pins>; led0 { label = "beaglebone:green:usr0"; gpios = <&gpio2 21 0>; linux,default-trigger = "none"; default-state = "off"; }; }; }; }; }; -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
