Is it possible to access GPIO and the connected LEDs?
My understanding is, that gpioleds should access the device tree:
leds {
compatible = "gpio-leds";
sys_led: led-0 {
label = "sys_led";
gpios = <&gpio1 RK_PC1 GPIO_ACTIVE_HIGH>;
linux,default-trigger = "heartbeat";
pinctrl-names = "default";
pinctrl-0 = <&sys_led_pin>;
};
wan_led: led-1 {
label = "wan_led";
gpios = <&gpio1 RK_PC2 GPIO_ACTIVE_HIGH>;
pinctrl-names = "default";
pinctrl-0 = <&wan_led_pin>;
};
lan1_led: led-2 {
label = "lan1_led";
gpios = <&gpio1 RK_PC3 GPIO_ACTIVE_HIGH>;
pinctrl-names = "default";
pinctrl-0 = <&lan1_led_pin>;
};
lan2_led: led-3 {
label = "lan2_led";
gpios = <&gpio1 RK_PC4 GPIO_ACTIVE_HIGH>;
pinctrl-names = "default";
pinctrl-0 = <&lan2_led_pin>;
};
};
…and make those available, but:
gpioleds0 at mainbus0: no LEDs
Further, I tried in /etc/rc.securelevel:
echo -n ' gpio'
/usr/sbin/gpioctl gpio1 0 set out led0
/usr/sbin/gpioctl gpio1 1 set out led1
/usr/sbin/gpioctl gpio1 2 set out led2
/usr/sbin/gpioctl gpio1 3 set out led3
…but:
# gpioctl gpio1 0 1
gpioctl: /dev/gpio1: Device not configured
How is it supposed to work?
