I'm not sure what board you have or what kernel you are running, however on
a Beaglebone Black running a 4.19 kernel, the LED settings are located in
the bone-common.dtsi file:
Note: From the BBB schematic, led1 is connected to the Ethernet port, so
perhaps you are trying to control usr0 LED.
Ex:
/opt/source/dtb-4.19-ti/src/arm/am335x-bone-common.dtsi
* leds {*
* pinctrl-names = "default";*
* pinctrl-0 = <&user_leds_s0>;*
* compatible = "gpio-leds";*
* led2 {*
* label = "beaglebone:green:usr0";*
* gpios = <&gpio1 21 GPIO_ACTIVE_HIGH>;*
* linux,default-trigger = "heartbeat";*
* default-state = "off";*
* };*
* led3 {*
* label = "beaglebone:green:usr1";*
* gpios = <&gpio1 22 GPIO_ACTIVE_HIGH>;*
* linux,default-trigger = "mmc0";*
* default-state = "off";*
* };*
* led4 {*
* label = "beaglebone:green:usr2";*
* gpios = <&gpio1 23 GPIO_ACTIVE_HIGH>;*
* linux,default-trigger = "cpu0";*
* default-state = "off";*
* };*
* led5 {*
* label = "beaglebone:green:usr3";*
* gpios = <&gpio1 24 GPIO_ACTIVE_HIGH>;*
* linux,default-trigger = "mmc1";*
* default-state = "off";*
* };*
* };*
Cheers,
Jon
