Yes, I hadn't quite grasped the layouts of this new board yet.

Oh, I wasn't aware of those. But indeed the LED is green, so it seems appropriate. I'll test it out, and see if I can make it glow red (jokes). > >> + }; >> + led2 { >> + gpios = <&gpio4 19 GPIO_ACTIVE_HIGH>; >> + }; >> + led3 { >> + gpios = <&gpio4 20 GPIO_ACTIVE_HIGH>; >> + }; >> + }; >> }; > > Gr{oetje,eeting}s, > > Geert >

Three general purpose LEDs are provided on the Falcon CPU board. Connect GP_LED1, GP_LED2, and GP_LED3 to the gpio-leds frameworks. These LEDs are arranged in a block of four LEDs on the board itself, but the fourth LED is as yet unidentified.
