Hello Jace,

If you use the KSDK1.3 +PE， you only need add the component of "fsl_debug_console",

then configure UART0 port and baud rate ,it can use printf*() to UART0 .

About the detail you can refer to this DOC : How to use printf() to print string to Console and UART in KDS2.0  

only need refer to the part of this DOC:

Hope it helps

Have a great day,
Alice Yang

Jace:

Have you compiled the hello_world example in the SDK's boards/.../demo_apps directory?  If so, you'll notice that the SDK defines a PRINTF() macro that behaves like the "ordinary" printf(), but specifically directs its output to UART0, or more properly, whatever the debug console is defined to be in your project.

I suggest you try compiling the hello_world demo as a starter.  Hope this helps!
