GPIO not work well on Jetson Linux 36.3

[627263202]

Jetson Linux 36.3+Orin NX + dev kit
I would like to control GPIO 22/40 pin , I did the follow test:
#1 modify pinmux xls and sync pinmux dtsi file
#2 flash Orin NX
#3 check voltage of 22/40 pin: 3.3v
#4 gpioset 0 123=0 , check voltage of 22/40 pin: 0v
#5 gpioset 0 123=1 , check voltage of 22/40 pin: 0v
pin 22/40:

xls:

pinmux dtsi:
spi3_miso_py1 {
nvidia,pins = “spi3_miso_py1”;
nvidia,function = “rsvd1”;
nvidia,pull = <TEGRA_PIN_PULL_UP>;
nvidia,tristate = <TEGRA_PIN_DISABLE>;
nvidia,enable-input = <TEGRA_PIN_DISABLE>;
nvidia,io-high-voltage = <TEGRA_PIN_DISABLE>;
nvidia,lpdr = <TEGRA_PIN_DISABLE>;
};
gpioinfo :

My question : in step 5 , the voltage should be 3.3v, but it is 0v.

Hi 627263202,

#1 modify pinmux xls and sync pinmux dtsi file

If you want to use the pins as Output, please configure it as Output/Drive 0 or Output/Drive 1.
Int PU/Int PD are invalid for Output pin.

#4 gpioset 0 123=0 , check voltage of 22/40 pin: 0v
#5 gpioset 0 123=1 , check voltage of 22/40 pin: 0v

Please use the following command instead.

$ sudo su
# gpioset --mode=wait `gpiofind "PY.01"`=0
# gpioset --mode=wait `gpiofind "PY.01"`=1
