Thanks! Indeed quite simple.

It is very simple. If you use Microblaze, an opb_mdm block is added
for the debug. Then, you have to go to Software Options and configure
the STDOUT to opb_mdm_0 (that is the instance). Finally exec XMD (in
bootloop mode) and write the following sentences:

connect mdm -uart
read_uart

Now you could dow any executable.elf and run it. The output is written
in the xmd console.

And if you have powerpc, add a opb_mdm ip core and select C_USE_UART
to 1. The following process is the same as the before one.

Would you mind sharing the solution? I'd like to know how to use JTAG
as UART in my design as well.

Solved.

Hi, I have seen about configuring the JTAG as UART since I have not
RS232 port in my board. I have found that Xilinx provides OPB_MDM as
uart with C_USE_UART PARAMETER, but in my desing I use PowerPC. In
powerPC the debug is done by jtag_cntlr and not by opb_mdm so console
says that "opb_mdm_0 is not accessible from processor ppc405_0".

Has anyone configured JTAG as UART in PowerPC?
