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.

I think I encountered this problem as well.
I found this patch in my history. Maybe it helps:

Subject: How to change UARTs RTEMS
Hello,
I'm using the Zedboard's BSP and my objetive is to print what goes
out through
the uart1 interface for uart0 and vice versa.
I thought changing the memory addresses of the “console-config.c”
configuration file would suffice, but it is not.
zynq_uart_context zynq_uart_instances[2] = {
{
.base = RTEMS_TERMIOS_DEVICE_CONTEXT_INITIALIZER( "Zynq UART 0"
),
.regs = (volatile struct zynq_uart *) 0xe0001000,
//it was 0xe0000000,
.irq = ZYNQ_IRQ_UART_0
}, {
.base = RTEMS_TERMIOS_DEVICE_CONTEXT_INITIALIZER( "Zynq UART 1"
),
.regs = (volatile struct zynq_uart *) 0xe0000000, //it was
0xe0001000,
.irq = ZYNQ_IRQ_UART_1
}
};
Do I have to modify more files like zyn-uart-regs.h?
Has anyone done it or can it guide me?
Thanks in advance.
