Flash Firmware from Browser
Flash your Ryzer device directly from your browser. No software installation required.
When do I need this? Browser flashing is only required for initial setup of a blank board, or to recover a device that won’t boot. For normal firmware updates, use the built-in OTA update feature which works over WiFi - no USB connection needed.
Browser Requirements
Browser-based flashing only works in Google Chrome or Microsoft Edge on desktop computers. Safari, Firefox, and mobile browsers are not supported due to Web Serial API limitations.
Before You Begin
- Ensure the 12V power adapter is connected - the board requires 12V power at all times
- Connect your Ryzer device to your computer via USB-C - this is only needed for manual flashing
- Close any serial monitors or other applications that might be using the USB port
