The "I Know This!" Paradox
In Jurassic Park (1993), Lex sits at the Silicon Graphics workstation running IRIX's 3D file navigator and declares: "It's a UNIX system! I know this!"
When an MCU developer logs into an Ubuntu Core shell, you feel that exact same comfort: bash, top, ps, standard POSIX tools. But the moment you try to apt install or write to /usr/bin, the illusion dissolves.
Why This Was Built (The Inverted View)
Coming from Zephyr RTOS / MCUboot to Embedded Linux usually means drowning in 2,000 pages of Yocto recipes.
Ubuntu Core is different: it's not a generic Linux distribution, but a modular firmware appliance. This visualizer inverts the usual perspective: we sit at PID 1 and look downward into the hardware strata, translating Linux mechanics directly into the flash maps, device trees, and pinmuxes you already understand.
How To Navigate
• Waypoints (0–5): Click the top bar buttons to dive from the orbital Top-Down view down to bare silicon.
• ⇄ Flip 180°: Rotate around the central Z-axis to inspect the stack from the reverse angle.
• Click Any Box: Swoop directly in front of that node to inspect its telemetry and Zephyr parallel in the right HUD.
• Mouse: Scroll wheel zooms/dollies; left-click drags to rotate; right-click pans.
