UART2 not working

[mathew_k_t]

Hi

Following is the result of loop back test in uart2.

I have used the default configuration in dts file except "fsl,uart-has-rtscts;"(I commented it). Why it is not working? Whats the error in default configuration?

When you are performing "echo hello" you sending this text into system console and as the console is associated with ttymxc0 UART the text finally arrives at the PC.
When you are performing "echo hello > /dev/ttymxc0" you sending the data into UART directly as ttymxc0 device not as a console.
And you are getting the same result. The text arrives at the PC.
However in case of "echo hello > /dev/ttymxc1" the text goes to UART2 however nothing is listening to UART2 device.

Have a great day,
Victor
