IMX28EVK, Redirecting DUART on AUART0 CTS/RTS at the u-boot

Hello!

I am trying to get the DUART on the AUART0 pins CTS/RTS, The u-boot prints fine log messages but key strokes from the console don't get processed by the u-boot. I am using the IMX28EVK board for that.

The pinmux is not that hard.

Also, I have put in a loopback mode the DUART and the u-boot sees the incoming characters

Does anyone have tried that before?

Best regards

Andreas

Fixed.

The ROM bootloader assigns DUART's TX and RX on PWM0 and PWM1 pins. I had to change the function of PWM0 and PWM1 to something else, GPIO.
