The camera sensor (ov5640) connected over i2c but never produces a single valid frame across every software configuration tried — different clock speeds, wifi on/off, different buffer/grab-mode settings, cable reseat, usb port swap, and connector re-lock. that combination (i2c control works, parallel image-data path never does) points to a physical fault in the ribbon cable, connector, or sensor.
