Hi All,

I have a strange problem on the USART0 (ttyS1) on sam9263 using KaeilOS distribution, on a EVB then I'm quite sure the HW is ok...
using a debug application running on user space, I can receive the characters on the serial port but I cannot trasmit, seems that the trasmission is not enabled.....is there any way to debug what is happening, maybe enabling kernel debug output?
any help or feedback is appreciate.
thanks
bob
