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.
