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

Thanks! Indeed quite simple.
