Crackle Cube Updater
Update the firmware on your Crackle Cube over USB, right from your browser.
Before you start
- Connect the Crackle Cube's USB port to your computer with a USB data cable (some charging-only cables won't work).
- Close any other app that might be using the Cube's serial port (Arduino IDE, serial monitors, other browser tabs).
- Keep the cable plugged in until the update says it's finished.
Install
Your browser will ask you to pick a serial port. Choose the one for the Crackle Cube (often called "USB JTAG/serial", "CP210x", "CH340" or "USB Serial").
Technical log
Trouble connecting?
- No port shows up: try another cable or USB port. On Windows you may need the CP210x or CH340 USB driver.
- "Failed to connect": hold the BOOT button on the ESP32 board, tap EN (some boards label it RST), release BOOT, then click install again.
- Stopped part-way: just run it again. The Cube can always be re-flashed.
