Hi!
Used the Navio 2 one year ago with my Raspi 3B and it was fully functional.
Sold this Raspi 3B some month ago.
Yesterday I bought a new Raspi (4, 8GB) and now I get an error message after starting ardupilot:
“ms5611: Failed – Reason: No connection”
All other tests passed.
Today I took another (new) SD card for Navio2, same error message.
Hi @polarspan,
Welcome to the community forum!
Is your Navio2 firmly attached to Raspberry Pi with screws? The failed test might indicate that the connection between the board and Navio2 is loose.
Yes screws.
Hi.
just lowered force a bit on the srews and now it is working 
Thanks for your input Liudmila !!!
