Hi NV team:
请问我现在使用Jetson_AGX_Orin_Pinmux_Config_Template_init.xlsm文件配置了GPIO的功能，生成了文件Orin-jetson_agx_orin-gpio-default.dtsi Orin-jetson_agx_orin-pinmux.dtsi 刷机配置好的IO功能。
能启动后动态修改吗？
比如在刷机前配置成了SPI2_SCK的功能，我在启动时，动态修改为GPIO3_PCC.00,请问支持这样动态修改吗？

Hi 809656875,

What’s the Jetpack version in use?

Please note that pinmux/gpio dtsi are loaded in early boot(MB1) stage rather than in kernel.
If you want to update it during boot up, you can configure them in kernel device tree to be loaded by tegra pinctrl driver.
You can refer to GPIO JP6.1 different behavior than JP5.1.2 - #3 by KevinFFF for details.
