Hello everybody 

 

I expose my problem ...

I create my own a20 card ( based on olimex a20 lime) ( 90% similar )

I have no problem with the hardware ....all work except ....leds  ( you know in /sys/class/leds ....)

But i need 3 leds ... so i write this in dts file ( sun7i-a20-olinuxino-lime.dts)

 

leds {

compatible = "gpio-leds";

pinctrl-names = "default";

pinctrl-0 = <&led_pins_olinuxinolime>;

 

green {

label = "a20-olinuxino-lime:green:usr";

gpios = <&pio 7 2 GPIO_ACTIVE_HIGH>;

default-state = "on";

};

red {

label = "a20-olinuxino-lime:red:usr";

gpios = <&pio 7 0 GPIO_ACTIVE_HIGH>;

default-state = "on";

};

blue {

label = "a20-olinuxino-lime:blue:usr";

gpios = <&pio 3 27 GPIO_ACTIVE_HIGH>;

default-state = "on";

};

};

 

 

 

and instead of 

 

led_pins_olinuxinolime: led_pins@0 {

allwinner,pins = "PH2"

allwinner,function = "gpio_out";

allwinner,drive = <SUN4I_PINCTRL_20_MA>;

allwinner,pull = <SUN4I_PINCTRL_NO_PULL>;

 

 

i wrote

 

led_pins_olinuxinolime: led_pins@0 {

allwinner,pins = "PH2", "PH0" , "PD27";

allwinner,function = "gpio_out";

allwinner,drive = <SUN4I_PINCTRL_20_MA>;

allwinner,pull = <SUN4I_PINCTRL_NO_PULL>;

};

};

 

 

It work fine with 4.4xx version of kernel and armbian 5

 

But i need some 4.6.1 functionnality's 

 

So i download the armbian 5.14 ( and i build kernel 4.6.1)

 

All hardware is ok and work except leds

 

After a ./ compile  ( completed ) , i changed the the dts file  with my leds parameters ...and nothing ....I have only the "green" led (in /sys/class/leds/ )

 

So i suppose that dts files were compiled the first time and will be never compiled again Or .... if you have a solution it will be cool !

 

I just going to be crazy 

 

Thanks a lot 

 

 

Ps: Excuse me for my very bad english .....I'm french 

There must be some changes in this area, but it's too soon to tell where is a problem, why the methodology changed or it's simply a bug. I haven't boot any board with 4.6.1 kernel yet.

I will try a other method ....a brutal method

Translation ...the cook for the target dts/dt.dtb fail .....hummm very strange ...i extract the dts file from armbian 4.4.5....... And in this version ...no problem 

 

 

Your answer is not a good news for me ...   but thanks for your help . You make a amazing work ! Thanks a lot Igor !

 

i ' ll try something harder .....
