I have a custom AM335x board.I want to configure GPIO0_1, GPIO3_10…etc as a GPIO.
If i try to change GPIO0_1(GPIO1) value through sys interface , nothing changed
sudo echo 1 > /sys/class/gpio/export
sudo echo out > /sys/class/gpio/gpio1/direction
sudo echo 1 > /sys/class/gpio/gpio1/value
sudo echo 0 > /sys/class/gpio/gpio1/value
When create .dtbo file, it effect the pin value but i couldn’t change the value from user space.
High-Side.dts
/dts-v1/;
/plugin/;
#include <dt-bindings/pinctrl/am33xx.h>
#include <dt-bindings/gpio/gpio.h>
#include <dt-bindings/interrupt-controller/irq.h>
/*

&{/chosen} {
overlays {
High-Side.kernel = __TIMESTAMP__;
};
};
/ {
fragment@0 {
target = <&gpio0>;
__overlay__ {
gpio-line-names =

What i need to change this GPIOx from user space?
Best regards.
