ps2avrGB keyboard firmware

This keyboard uses the port of the QMK firmware for boards that are based on the ps2avrGB firmware.

Note that this is a complete replacement for the firmware, so you won't be using Bootmapper Client to change any keyboard settings, since not all the USB report options are supported.

Installing

First, install the requirements. These commands are for OSX, but all you need is the AVR toolchain and bootloadHID for flashing:

$ brew cask install crosspack-avr
$ brew install --HEAD https://raw.githubusercontent.com/robertgzr/homebrew-tap/master/bootloadhid.rb
$ pip install pyusb

Then, with the keyboard plugged in, simply run this command from the qmk_firmware directory:

$ make hb85
$ bootloadHID -r hb85_default.hex

Setting the board to bootloader mode

Hold the F3 key while plugging the USB cable.

Troubleshooting

From my experience, it's really hard to brick these boards. But these tricks have been useful when it got stuck in a weird scenario.

1. Try plugging the board in while holding the bootloader key. This will force it to boot only the bootloader without loading the firmware. Once this is done, just reflash the board with the original firmware.
2. Sometimes USB hubs can act weird, so try connecting the board directly to your computer or plugging/unplugging the USB hub.
