In the r35.3.1 version, I want to modify the pinmux and generate new dtb and image files, and then remotely replace them on the orin nx without flash. How should I achieve this?
Hi zjy523213189zjy,
Are you using the devkit or custom board for Orin Nano?
To update pinmux dtsi, you have to reflash the board to apply the change.
They are configured in MB1 so that they are not included in kernel DTB.
You can try to generate OTA payload with the updated pinmux configuration and perform image-based OTA update.
