Pinmux

[2639376969]

Hi, all:
I want to use GPIO3-PA.05, but this pin is used for i2s. I see that i2s is disabled in the following file:

hardware\nvidia\soc\t23x\kernel-dts\tegra234-soc\tegra234-soc-audio.dtsi
tegra234-soc-audio.dtsi.log (27.8 KB)
Do I need to modify any other file?
I am using the Orin Nano platform and jetpack35.5。

Hi 2639376969,

Are you using the devkit or custom board for Orin Nano?

If you want to use this pin as GPIO, please just configure it as GPIO3_PA.05 with Output/Drive 0 in pinmux spreadsheet.
Please refer to Jetson Orin NX and Nano Series — NVIDIA Jetson Linux Developer Guide 1 documentation to apply the change and you don’t need to modify tegra234-soc-audio.dtsi.
