Python throws an error when using the pinmux script with .dtsi files generated from the pinmux Excel file. This error is thrown even when generating with the unmodified Excel file.

The gpio-default and pinmux .dtsi files attached to this issue were generated by an unmodified version of the pinmux spreadsheet (Jetson_AGX_Orin_Series_Pinmux_Config_Template_1.5.xlsm). I am seeing an issue with a key error from the pinmux Python script (.dtsi files are located in the t19x directory):

The “pinmux-dts2cfg.py” Python script is from the “Jetson_Linux_R35.3.1_aarch64.tbz2” driver package (BSP). Changing the version passed to the Python script to 1.5 did not fix the KeyError output. Let me know if there is a workaround for this issue. Thanks.

Hi,

You hit error because this usecse is not needed. Orin AGX pinmux file is not cfg file. It is only dtsi file.

Only T186/T194 need to convert pinmux dts for cfg file. Orin does not need to do the conversion.
