FC NeuronRC AT32F435mini uart2 uart3 not working

[konstantinfpv]

Current Behavior

Soldered MSP Lidar+Optical Flow (microair mtf-01) to R3 T3 pins, set UART3 = MSP, Set Rangefinder = MSP, OpticalFlow = MSP. Rangefinder and Optical flow icon are red. Microair mtf-01 is working properly on other INAV board.
Soldered Matek M8Q GPS to R2 T2 pins, set UART2 = GPS, set use GPS for navigation, set ublox protocol baud 115400, GPS icon is red, no update in GPS tab.

Steps to Reproduce

1. Solder to pads t2 r2 GPS
2. Solder to pads t3 r3 microair mtf-01
3. Solder GPS and microair mtf-01 V and G wires to 5v and G pads.
4. Connect FC to PC, connect to configurator.
5. Connect lipo if needed.
6. Check that GPS and microair mtf-01 are working (lights on)
7. Setup GPS and microair mtf-01
8. GPS, Lidar, Flow icons are red.

Expected behavior

On other INAV boards GPS is working, microair mtf-01 is working (can be calibrated and can see logs with data)

Suggested solution(s)

Maybe wrong resourse adress for TX2 RX2 TX3 RX3 pins
