Hi, I recently purchased a Navio2 and followed all the setup instructions, but I can’t get it to boot on my Raspberry Pi 4 board. I’ve tried 2 known working Pi 4 boards but got the same results. Thinking I may have gotten a bad Navio2 I borrowed my friends Pi3 and it boots up no problem.
We have a couple of reports of the issue with booting on Raspberry Pi 4. The bootloader packages of Raspberry Pi OS were changed, and now there can appear some challenges with the correct booting. But our devs have found how to fix that, and we’re currently on the testing stage. Once the updated image is out, I’ll let you know.
There’s a workaround suggested by one of our users which you may try. But I’ve not tested this myself, so I can’t guarantee it’ll work.
Hi @liudmila.slepova, Thanks for the reply. I’m glad to hear there is a new image in the works. If you need I can test it out and provide feedback.
I tried the suggested workaround by replacing the start4x.elf file. The Pi 4 proceeded a lot farther but now the Navio2’s green light turns off and the screen is blank: - YouTube
Thanks for your offer! We’re not updating the functionality though, this update is only required to tailor some RPi 4 boards. So, we just need to make sure that the image works stable.
I can hardly guide you in this for now, as I’ve not tried it. I assume this workaround doesn’t work properly in all the cases. Let’s wait for the update, then. It should help with this issue.
The documentation on Emlid’s website clearly says the Navio2 should be compatible with a Raspberry Pi 4, but this is not accurately advertised. If the new image is not released soon, can Emlid help setup a return process for boards purchased through official distributors? I think I may switch to a Pixhawk flight controller instead as there seems to be a lack of movement on this.
It’s on the testing stage at the moment. Once it’s out, I’m surely let you know.
Navio2 is compatible with Raspberry Pi 4 boards. The issue with the bootloader came out recently and only for some newly produced RPi 4 boards. It works just fine with older RPi 4 we have in our office, for example.
I understand that this impacted your plans. We’re working on this to make those affected boards working fine again. Since those changes came from the other side, we couldn’t prepare for them beforehand. However, we’re aimed to provide you with the solution.

Thanks for your feedback on this!
