Camera Power Guide

This guide provides step-by-step instructions for selecting and powering the camera interface on the AstrOptix Board. It describes how to use the Camera Selection Utility (display_pop_up.py) to activate the LVDS camera (EV9520L), the MIPI camera (EV9500M), or both simultaneously, and how to save a permanent power mode that persists across reboots.
