Still no luck … here is the output from the firmware_update.sh
pi@raspberrypi ~/Desktop/GoPiGo/Firmware $ sudo ./firmware_update.sh
ATTENTION! Important!
BEFORE PROGRAMMING THE GOPIGO FIRMWARE, DISCONNECT THE MOTORS.
Please confirm that you’ve disconnected the motors.
Have you disconnected the motors before programming the firmware? (y/n)
