hi,
in k3-am68-sk-base-board.dts, the GPIO0_48 has been configed，
rpi_header_gpio0_pins_default: rpi-header-gpio0-pins-default {
pinctrl-single,pins = <
J721S2_IOPAD(0x0a8, PIN_INPUT, 7) /* (U24) MCASP0_AXR14.GPIO0_42 */

};
if i want to control GPIO0_48 from user space，how to do it？

Can i following this guide to control GPIO, do I need to change the *.dts file? I use SDK9.1, thanks
