Guys,my F405 Wing was flashed arduplane3.9.9,but the servo output trim at 1100,but I have set it at 1500,can some people give any suggestion to solve the problems
Check your mode and the SERVO3_function, trim, min, and max in the full parameter list. If all appears good, turn log_disarmed on and post a .bin log from your bench test.
I use another computer to flash the firmware again,it works right now,but I still don’t know why it didn’t work by use that computer.
My guess is it uploaded the wrong firmware for that board, maybe your computer mis-recognized the board type.
