How to use JTAG UART with normal UART in a Qsys System

I have included a JTAG UART and a normal UART into my system. The JTAG UART shall be eventually removed but must be used for the time being. As far as I understand, I should merely goto the BSP editor settings and choose which of the two are to be used for stdin, stdout and stderr.

Now, basically when I choose the uart_0 in BSP editor and try to run my design I get the this message:

"The expected Stdout device name does not match the selected target byte stream device"

I have explicitly select uart_0. What does this message mean then when it says "expected Stdout device"?
