The tool provided by our Expansion Card manufacturing partner is unfortunately only built for Windows and we had to obtain permission to release it publicly for firmware flashing purposes. We know this is not ideal for our Linux Community, but there was no other available option given it is their software.
You don’t have to have the Expansion Card in a Framework Laptop, and if you have a friend or family member with a Windows PC, you can use their machine to quickly flash the firmware. Just make sure the Expansion Card is plugged into the PC when you run the executable.
