Jetson thor 无法使能GPIO3_PU.04

gpioinfo gpiochip2 | grep U.04 #查找offset
        line  11:      "PU.04"       unused   input  active-high
gpioset gpiochip2 11=1 #输出高
gpioset gpiochip2 11=0 #输出低

使用如上指令控制t5000的J5（GPIO3_PU.04）管脚没有反应，控制H52(GPIO3_PF.07)就可以

dts.zip (52.9 KB)这里是当前的设备树和pinmux配置

Hi hansguo,

Are you using the devkit or custom board for Thor?
What’s the Jetpack version in use?

Have you configured the pinmux for PU.04 before use?
If not, please configure it as GPIO/Output/Drive 0 or 1 in pinmux spreadsheet.

Hi,

Yes,I’m using the custom board for Thor.
JetPack 7.1 with Jetson Linux 38.4
I only configure the pinmux in BCT pinmux dts file in the dts.zip above.
