    We've seen a couple reports of this. It's possible that your USB cable is bad or the battery wasn't powered when you attempted to upgrade.

    Hi Amir, I think you may have missed the point. This error appears when attempting to load the hex file into the Teensy Loader app before any attempt is made to download the image to the board.

    What OS are you on and how big is the hex file you downloaded?

    macOS Sierra 10.12.2, Teensy Loader 1.33, flybrix-firmware-1.4.0.hex (290081 bytes according to Get Info). The download appeared to work fine with a download successful status in the Teensy Loader app. A test flight of the copter confirmed the new copter OS was functioning ok.

    I am getting the same message when my flybrix board is not powered. I suspect the Teensy loader defaults to some other expected hardware and until it talks with the FlyBrix board it does not know how much space is truly available.

    I would try powering my board to prove this thoery, but my son has already used it so much that one of the power lines broke off and I need to brush up on my soldering skills to fix it.

    I have been able to confirm with the chrome Flybrix Configuration Utility that flybrix-firmware-1.4.0 was successfully loaded to the copter using the Teensy Loader on macOS Sierra 10.12.2.

    Once I attached my powered flybrix board the error message went away AFTER I hit the program button on the board.
