Hi Team,
We are using Orin AGX ( 5.10.104-tegra / L4TR35.1.0_V0.1). In our customized carrier board we re using UART2 as RS485, Default this UART port is mapped with debug console. We have disabled but still kernel message are displaying . How we can disable that also to particular serial port. ?

please check the similar topic, Orin series is same as Xavier series that using combine UART. we have not verify the use-case by disabling that. we cannot guarantee the real use-case for transferring data as it’s not in our supported use cases/features.
