JTAG_UART stuck in printf

I'm trying to setup a NiosV and have printf appear over the JTAG_UART. I've used only the default settings when generating the bsp (just the generate command, no set_settings). I notice when I debug, anytime I step over a printf statement, it never returns (also, no print statements appear in the juart-terminal).

However, if I just do a direct pointer access to the JTAG_UART base address, I successfully see characters printed in the juart-terminal.

Looking in the bsp's summary.html, it appears that it has linked the jtag_uart. Ex: hal.stdout Value = jtag_uart_0.

I also have a fair chunk of CPU block ram memory (262 KB total, only using about 16 KB right now for hello world).

Any ideas what the issue here is?
