Getting FlashFloppy onto the Gotek SFRC922D

These flash floppy emulators from Gotek are great. But they are even better when they have the FlashFloppy firmware loaded.

The SFRC922D model I have seems to have some extra holes under the serial/boot jumpers.

I chose to use the USB/DFU programming method for which you will need a USB A-A cable.

Here's how I put the Gotek into boot mode for DFU:


Jumpers for boot/DFU mode. Wirelinks above the white connector.


Once in boot mode you can program the device using the dfu-util:

I'm using OSX, and used homebrew to install the dfu-util.

brew install dfu-util

dfu-util --list
