pinmux配置,但K49、H51这两个GPIO没有输出高电平

Hi, NVIDIA

问题:我们的AGX Orin 64G custom board,pinmux配置,但K49、H51这两个GPIO没有输出高电平。
补充信息:
1、pinmux excel表格:

2、生成的pinmux dtsi文件《Orin-jetson_agx_orin-pinmux.dtsi.txt》

Orin-jetson_agx_orin-pinmux.dtsi.txt (65.6 KB)

3、在Orin Ubuntu系统命令gpioinfo查询

4、万用表测量K49、H51低电平

Hi 751244340,

Please configure the pin as Output/Drive 1 in pinmux spreadsheet.
Int PU/Int PD are invalid for Output pin, they are used for Input pin.

What’s the Jetpack version in use?

Hi KevinFFF,

jetpack6.0

更换pinmux.dts的方法,除了flash.sh烧录,能在Orin Ubuntu替换文件的方法更新pinmux吗?

1、Int PU/Int PD、Z这三个状态什么时候配置?GPIO方向输入的时候才配置吗?
2、输出低电平配置 Output/Drive 0 ?输出高电平配置 Output/Drive 1?

Sorry that you can only reflash the board to apply the pinmux change.
Or you can try to update the pinmux register manually, but it is effective temporarily.

Int PU/Int PD/Z are valid for Input/Bidirectional.

Correct, they are the default state after boot up. You can also control them through gpiod.
