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
Solved! Go to Solution.
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.
