3.3 Flashing Firmware using ESP32 Flash Download Tool
Follow these steps to flash firmware onto your device:
- Download the ESP32 Flash Download Tool (refer to the official LILYGO GitHub for the latest version).
- Open the tool and select the correct Chip Type (ESP32-S3) and LoadMode (USB).
- Load the firmware.bin file and other necessary files as specified in the firmware note.
- Select the correct COM port for your connected device.
- Press and hold the BOOT button on the board.
- While holding BOOT, press the RST button.
- Release the RST button, then release the BOOT button.
- Click START in the Flash Download Tool to begin the flashing process.

3.4 Software Development
The LILYGO FabGL VGA32 supports various development environments:
- Arduino IDE: Install the ESP32 board package and relevant libraries (e.g., TFT_eSPI).
- PlatformIO: Configure your project for ESP32 and use the appropriate board definition.
- ESP-IDF: For advanced development, refer to the official Espressif IDF documentation.
- MicroPython: Flash MicroPython firmware and program using Python.
4. Operating Instructions
The FabGL VGA32 board offers several functionalities for your projects:
4.1 VGA Output
Connect a VGA-compatible monitor to the VGA port on the board. Ensure your code initializes the VGA display correctly to output graphics or text.

5. Maintenance
To ensure the longevity and proper functioning of your LILYGO FabGL VGA32 board:
- Keep the board clean and free from dust and debris.
- Avoid exposing the board to extreme temperatures or humidity.
- Handle the board with care to prevent damage to components or connectors.
- Store in an anti-static bag when not in use.
6. Troubleshooting
If you encounter issues with your FabGL VGA32 board, consider the following:
- No display after writing program:
- Check if factory test files in the firmware folder can be flashed. If there is still no display, the board or screen might be faulty.
- Delete the
<TFT_eSPI>library and replace it with the one from the main page's library directory. - When opening Arduino IDE, if it prompts to upgrade the library, choose not to upgrade, otherwise it will overwrite the configuration of the
<TFT_eSPI>display.
- USB port not found or upload mode issues:
- The board uses USB in the JTAG upload port. When printing serial port information, the USB_CDC_ON_BOOT configuration needs to be turned on.
- If the port cannot be found when uploading, or the USB is used for other functions, the port may not appear. Please enter the upload mode manually:
- Connect the board via the USB cable.
- Press and hold the BOOT button.
- While still pressing the BOOT button, press RST.
- Release the RST button.
- Release the BOOT button.
- Upload your sketch.
- If the above steps are invalid, burn the factory binary file to check if the hardware is normal.
