Firmware Flashing

This guide will walk you through flashing or updating the ESP32-S3 firmware for your TechyPad hardware. Keeping your firmware up-to-date ensures maximum stability and compatibility with the latest desktop app features.

1. Download the Firmware File

Whenever there is a new firmware release, you can find it alongside the desktop application.

  1. Navigate to the Releases page.
  2. Look for the file ending in .enc (for example, TechyPad Firmware v1.0.0-beta.enc).
  3. Download this file to your computer.

Note

The .enc extension means this firmware is encrypted specifically for the TechyPad's OTA (Over-The-Air / USB) updater.

2. Flashing via the TechyPad Desktop App

The easiest way to update your firmware is directly through the official TechyPad Windows app.

  1. Connect via USB: Ensure your TechyPad is plugged into your PC via a USB data cable. (Firmware updates cannot be performed over Bluetooth).
  2. Open the App: Launch the TechyPad Desktop application.
  3. Go to Settings: Click the gear icon or navigate to the Settings menu.
  4. Firmware Update Section: Locate the Firmware Updater section.
  5. Select File: Click the button to browse for a local firmware file, and select the .enc file you downloaded in Step 1.
  6. Flash: Click Update or Flash. Do not unplug your device while the progress bar is moving!
  7. Reboot: Once complete, the TechyPad will automatically restart and reconnect.

Troubleshooting Firmware Updates

  • "File must be an .enc image" Error: Make sure you downloaded the .enc file and not the .bin or source code files.
  • Device Disconnected: Ensure you are using a USB data cable, not just a charging cable. Try a different USB port on your motherboard.
