NanoPi Neo Core GPIOA0 would'n toggle

Coby Levy


hi everyone,

I'm running latest  Armbian 20.08.1 Buster with Linux 5.8.5-sunxi on a Nanopi Neo Core.

I cannot understand why I cant turn GPIOA0 on\off, can't configure it as output.

I have no problem with any other GPIOs, just this one.


command i'm using:

gpio mode 0 output
gpio write 0 1

I managed to make the GPIO as Output using this command, but still no go - the output cannot be set.

echo 0 > /sys/class/gpio/export
echo out > '/sys/class/gpio/gpio0/direction'


dmesg don't show any errors.


I checked H3 documents, there's no conflict in the mux with other GPIOs,
and just to be sure i turned UART everything off (UARTs, i2c, i2c, etc..).


could someone please guide me?

hi, thank you for your reply.

this is the output (it shows a proper toggles).

gpiochip0: GPIOs 0-223, parent: platform/1c20800.pinctrl, 1c20800.pinctrl:
 gpio-0   (                    |sysfs               ) out hi
 gpio-10  (                    |nanopi:blue:status  ) out lo
 gpio-166 (                    |cd                  ) in  lo ACTIVE LOW
 gpio-204 (                    |usb0_id_det         ) in  hi IRQ


but I think I figured out what's the problem is, Apparently - the GPIO is malfunction, I might burned it.


I tested it with a new installation,
and did the same on another board I have here.

thank you for your help,
