Firmware Updating

This guide will show how to upgrade the firmware on your AVR XMEGA based device.

If your device has a USB Bootloader, follow these instructions.

Tools required:

  • AVRISP mkII, or similar PDI capable programmer
  • AVR Studio 4 IDE (Integrated Development Environment)
  • HEX and EEP files for the device, found on the product's page (Look for the HEX icon).

A regular AVR programmer might not work, the programmer needs to be PDI capable. PDI is the new interface to program XMEGA microcontrollers.

Instructions to install the tools:

  1. Install AVR Studio and USB driver
  2. Connect the programmer to the computer and auto install the hardware

A more detailed guide on how to install the tools is found here.
