Just upgraded my Flamewheel 550 Hex from the APM 2.0 board to APM 2.5 (plus the ublox GPS) (all directly from 3DR). On firmware installation, at the end of the "verify" phase, there's an error message stating that the firmware upload was successful but that verify failed "exp 77 got 37 at 35124." I repeated the upload four times with the exact same result. Does this indicate a defective board, or?? Thanks for any help!
