Navigator Installed -- No Board Running (Help!)

Hi BlueRobotics community,

First want to start off by saying thanks to the community you have been tremendously helpful in me reviving our BlueROV2 we bought back in 2017.

I was running into issues with my old Pixhawk 3DR px4 and after looking around decided upgrading to the Navigator would be the best/easiest use for us. I am not a computer science/software engineer by trade (Environmental field here) so I have been running into some snags. ChatGPT has been pretty helpful in scouring the forums for me to help me troubleshoot.

Basically with the old Pixhawk I couldn’t get all of the functionality we wanted (light control, ping sonar, grabber thing) so upgraded. Spent the day installing the Navigator on to the Raspberry Pi 3 Model B Rev 1.2 - armv7l (Cortex-A53) that was on the system and when I boot up BlueOS it shows “No Board Running”. I followed the guides on the Navigator page to install and I’m pretty sure it’s all on correctly (I am only slightly unsure because it’s not working). Green & Blue lights are on on the Navigator, Red and blinking Green lights are on on the Pi. BlueOS boots up when using the tether. I can see through the camera on Cockpit & QGroundcontrol.

I’m a new user so I can’t upload attachments (was going to upload my ChatGPT messages). Basically it ended with it saying that my brand new board might be faulty and I just don’t want that to be the case! Any help is greatly appreciated as I haven’t found this issue on the forums (maybe it’s out there a link would be appreciated if so). THANK YOU SO MUCH FOR ANY HELP!

Hi @ZJennings, welcome to the forum :slight_smile:

Our Navigator flight controller board is only compatible with the Raspberry Pi 4, so unfortunately will not work with a Raspberry Pi 3B - sorry for the news!

If it’s relevant, we do have a dedicated Navigator retrofit guide for our older Pixhawk-based ROVs that should walk you through the requirements and relevant setup steps to get things up and running.

That said, if you want to continue with your current Raspberry Pi board then you’ll need to either return to your Pixhawk, or use some other independent flight controller board. You’re welcome to ask other questions here if you run into snags with either approach.

Right there in the first sentence of the product description… well that makes sense. I’ve bought a Raspberry Pi 4 and will be continuing down this road!

Thank you so much for your quick response Eliot!
