The device is shipped with test firmware installed. To burn a proper firmware, you will need:
- Atmel USB DFU Programmer from https://sourceforge.net/projects/dfu-programmer/
- Actual firmware files, which in worst case scenario you have to build yourself
- Incorrect instructions from https://store.ryscc.com/blogs/news/upgrading-the-firmware-on-a-chameleonmini
- Correct instructions (and a .bat file) in the firmware documentation
The instructions on the blog page are incorrect because Rev G hardware uses ATxmega128A4U instead of ATxmega32A4U. Why? Probably an outdated version of hardware.
