Connect & flash
- Connect the device to this computer with a USB data cable.
- If the device does not show up, hold the BOOT button, press RESET once, then release BOOT.
- Press Flash, choose the serial port and wait until it says Installation complete.
Help
- No port in the list? Install the USB driver for your board (CP210x or CH340), then reconnect.
- Linux: your user needs access to the serial port (usually the
dialoutgroup). - Flashing erases the device before writing the new firmware.
