AM3356: Set GPIO in U-Boot and keep it in Linux

Thomas Thielemann

Part Number: AM3356

Tool/software:

I managed to set a GPIO port in U-Boot. But while booting Linux the state is cleared and set again. First approach was by find a way to disable the reset in device tree. Second was was to use "gpio-leds" in device tree. But there is a small gap and the GPIO is reset and set after about 1 s. What is the right solution to not reset the GPIO?
