How to change UARTs RTEMS

[mfg]

Thanks for the reply Jan.

In your path you have xilinx_scosa, is it some xilinx's board?

My console-config is different, it hasn't console_tbl structure (I 
attach it to the mail).

I did not know there was a list of rtems developers, I'm going to ask 
that list, thank you very much.
