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?
