Since the base OS for GoPiGo OS and Raspbian for Robots Buster (October) is the new updated Raspberry Pi OS, and that one does not allow us to flash the firmware when on a Pi4, I’ve pulled these out and they are not currently available for downloading.
I am not able to revive my red board, so it’s pretty serious if you attempt to upgrade the firmware when using a Pi4. True, there’s no reason to upgrade it as we’ve been on the same firmware for over 2 years. However anyone following an old tutorial might be told to upgrade.
These OS images should be brought back online pretty soon.
