CUAV Nora+ UART problem at startup

Hey, everybody!

I started working with Nora+ and a problem appeared. I connected my telemetry model via UART - and it does not work on this controller.

What is the problem - right at startup, as soon as the flight controller is powered and booted - any of my devices that are connected to any of the UARTs hang and stop working.

But as soon as I’m on the go, while the flight controller is powered on, and I re-pin the UART connector - the devices start working fine until I either software reset the controller or do a “power circle”.

All this visually looks like - for example, I take my ELRS module or wifi module on ESP32 - at startup on the devices LEDs hang and do not blink and also do not react in any way.

I have three of these new controllers and they all have this problem. That said, I have not had this problem on any other controller. Also tried all kinds of configurations and variants of operation, different firmware versions - the result is the same.

I would be extremely grateful if you could help with this problem.
