Hi Sergei,
I specified that when the bootloader calls the kernel and I did see that
the baudrate is correct and I have some messages but when the system is
crashing I cannot see printk messages. For instance, I step with JTAG
and I can see that printk(KERNEL_WARNING "unable to open initial
console") is called but on the terminal I cannot see the message. The
same, die() is called but there is no messages on UART terminal.
Thanks,
Andrei

Have you specified "console=ttyS<n>,<baudrate> as the kernel
parameter?
