We are using Orin AGX module. While generating DTB file getting error like below , even though default pinmux files.
Please somebody suggest solution for error.

Moving this topic to the Jetson category for better exposure.

hello vardhaman.k,

you don’t need to execute python tool to covert them for Orin series.
since Orin is now reading *dtsi formats for pinmux configurations.

please see-also AGX Orin’s flash configuration file, for example, p3701.conf.common
you’ll see this line, PINMUX_CONFIG="tegra234-mb1-bct-pinmux-p3701-0000.dtsi";

please see-also developer guide, Pinmux Changes.
thanks
