Your Jetson Camera Won't Enumerate. Here's the Path to a Working Stream.
No /dev/video0. No frames. No useful error.
This is the flowchart we actually follow on client hardware, in the order that finds
the fault fastest.
What's in it
- → The check order that isolates the fault fastest, from device tree through I2C, clocks, and lane config, so you stop guessing which layer is broken.
- → What each i2cdetect result actually means. A UU is not a failure, and a missing address is not always a wiring problem.
- → The active-low reset GPIO trap. Polarity written the obvious way leaves the sensor held in reset, and nothing in the logs says so.
- → Where your JetPack version changes the answer, because the same sensor needs different handling across L4T releases.
- → The point where the fault is the carrier board rather than your code, and how to prove it before you spend another day in software.
It ships with a companion Claude Code skill that runs most of these checks for you. Both come from bring-up work on production Jetson and MediaTek Genio hardware, not from a datasheet summary.
