Hi Sir,
I have iMX8M mini EVK and I am able to connect my iMX8M mini to my laptop via USB Micro B debug port of iMX8 Mini. and i am bale to see the console output in putty / minicom.


from the documents i came to know that
The iMX8M has four independent UART Ports (UART1 – UART4). 

But On the EVK board, only UART3 is available and the UART2 is used for Cortex-A53 core, and UART4 is used for Cortex-M4 core.

The Pin details for UART 3 is -
TXD   -   Pin 8

RXD   -   Pin 10

Now i want to test UART3 of iMX8M Mini. 
I mean to say -
1. I want to connect iMX8M mini  USB Micro B debug port to my laptop and see the console.
2. Then I want to connect iMX8M mini UART3 to my laptop via some USB to serial convertor
3. Now I want to send some data say "Hello" to UART3 from my laptop and want to see this string in console / putty.

so basically i want to test UART3 TX and RX.
Please suggest me how can i do this or test UART3 .

Thanks & Regards,
