PiHawk LED - solid purple and can't connect to MP

#1

Damn. I thought I was going to do some final refinements to the trim this morning. But when I connected the battery I didn’t get the regular boot sequence on the Pixhawk. At boot up the main LED goes right to solid purple and doesn’t change. The blue light labeled ‘ACT’ is blinking too.

In addition, when I went to connect to Mission Planner (MP), it errored out telling me it couldn’t find the com port. I tried it with another machine which I’ve been successfully using with MP and it gave the same error.

At this point I’m pretty much at a loss at what to do next. I thought I had everything up and running and bah…

Any help is appreciated.

Additional information:

The LEDs under ‘FMU’ labeled ‘PWR’ and ‘B/E’ are dark/off.

A purple light on a Pixhawk typically indicates that the system is in Failsafe mode . This mode is activated when the vehicle encounters an issue during flight, such as losing manual control, a critically low battery, or an internal error.

To fix this, you should:

  1. Check your failsafe settings in your flight software to ensure they are configured correctly.
  2. Ensure that your RC or data link is functioning properly to avoid unintentional failsafe triggers.
  3. Update your Pixhawk with the latest firmware using your flight software to ensure all known bugs are fixed.
  4. Check to ensure your battery is charged.

Regarding the Mission Planner not finding a comm port, this issue can often be resolved by:

Checking that the drivers are properly installed on your computer. You may need to install or update them.

Connecting the Pixhawk to your computer, then rebooting the computer to prompt it to assign a COM port to the USB connection.
