Problem using UART2 (/dev/ttyS2) with NanoPi NEO Core 2 #2

Hello,

I'm having a problem using the NanoPi's UART2 port. I want to communicate the Nano Pi with an ESP32 through that port. I tested the signal in both devices separately and both work well but when I join the ports the communication stopped even when is just one direction. GNDs are joined. We tested with different devices shows the same behaviour. I don't think it could be an electrical or programming issue and I think something has to be disabled in the NanoPi.

Anyone had the same issue?

Thanks in advance
