I want to use additional UART port in u-boot along with existing UART console. How can I do that, I had made necessary changes in dts file, like enabling the status to OKAY. I am stuck at, How to initialize a particular serial port using u-boot cmd?

Hi @C Kumar

I fear than default uBoot commands does not manage any UART other than the console. You should write your own commands inside uBoot for that.
