CrowMotion Flasher

Flash the head tracker or the CrowLink bridge straight from your browser. No drivers, no toolchain.

Flash

  1. Plug the board into this computer over USB-C.
  2. Click Connect and pick the serial port (USB JTAG/serial).
  3. The right firmware is chosen automatically: ESP32-C3 gets CrowMotion, ESP32-C6 gets CrowLink.

This browser cannot flash over USB. Use Chrome or Edge on a desktop computer. Flashing needs a secure (https) page.

If the board is not detected

  1. Use a data-capable USB-C cable (many are charge-only).
  2. Hold the BOOT button while plugging in, then try again.
  3. Close anything else using the serial port (serial monitors, IDEs).

First install on a used board? Choose "Erase device" when offered, it clears old settings cleanly.

What gets flashed

Complete firmware images (bootloader, partition table, app) built and published automatically from tagged releases of crowpilot-fc/crowmotion. After flashing, updates can be installed wirelessly from the device's own config UI.
