I have a new pixhawk, right out of the box. I’m still waiting on parts, so I thought I’d mess with it, but I’m wondering if it is healthy.
In searching this forum, I’ve seen similar (but not identical) symptoms; sometimes they mysteriously go away, sometimes the thread just ends, and sometimes the thread has seemingly contradictory info about what the LEDs mean.
Video Version
I do this:

…and I think it is not starting up correctly. After the video, the state does not change for minutes and minutes.

Here is what I do:
- plug in the buzzer so I can hear it
- plug in the switch so I can see its light
- plug the pixhawk into a USB port
Pixhawk starts up.
FMU PWR LED goes steady green, stays green forever.
FMU B/E LED blinks rapidly for 4-5 seconds, then goes off forever.
I/O PWR LED goes steady green, stays green forever.
I/O B/E LED blinks rapidly for maybe a half second or less, then goes steady orange, stays steady orange forver.
I/O ACT LED starts blinking at 2 Hz right at power on and does that forever.
The “main” LED never lights up.
About a second after the FMU B/E LED stops its rapid blinking, the buzzer plays the happy sound, as if everything is okay (I think).
The switch light is blinking red rapidly, faster than the blue I/O ACT LED, slower than the amber FMU B/E LED was blinking.
MORE INFO
Nothing ever comes out of the serial port.
I’ve tried several USB cables, on many USB ports on two computers, and two USB chargers (0.7A, and 1.0A); changing does not make a difference.
I have tried reseating the SD card several times.
I have pushed the button in the side next to the USB port. The only difference I see between that and the cold power-on startup is the IO B/E LED stays steady amber through the reset.
I tried letting Mission Planner connect to it, but it would not (as I expected).
I think what I should see is:
- both green LEDs stay on steady
- both amber B/E LEDs eventually go out
- ACT indicates GPS status, probably blinking at some rate since it is not hooked up
- the main LED starts flashing multiple colors
What else can I try? Thanks!
