Power redundancy not met: 0 of 1

Hey folks,
I firmwared to 1.11.0 version. Reset all params, calibrated everything and now I’m unable to arm copter.
It says: Power redundancy not met: 0 of 1

What is it and how to fix it?

Are you sure the FC is seeing the battery?

Hi. I have the same problem. Have installed firmware 1.11.0, there was a problem: power redundancy not met: 0 instead of 1. You have to solve this problem?

I am not yet using 1.11.
You should create an issue here, sound like a bug:

Rolled back to 1.10.0. Everything works fine now. I wonder where I can download 1.10.1 firmware?

Have you tried:
setting COM_POWER_COUNT to 0 as a workaround?
If not could you please try this? It would be helpful to know if this fixes it.
Here is where you can get 1.10.1:

Hello. It helped me, the warning disappeared, the engines started.

Great - I’m sure you won’t be the only one that gets that.

I’m getting the same issue with a pixhawk 1 FMU with PX4 1.11.0 firmware. I’m going to try 1.10.1
