    Hi, 

    Two steps:

    1) add the file utils/uartstdio.c to your project. Ad it as a symbolic link.

    2) inside the file you call functions from this file, insert at the beginning #include utils/uartstdio.h

    Do not forget to read the code inside .c file and the comments of each function.

    #include "inc/hw_memmap.h"
    #include "inc/hw_types.h"
    #include "driverlib/debug.h"
    #include "driverlib/fpu.h"
    #include "driverlib/gpio.h"
    #include "driverlib/interrupt.h"
    #include "driverlib/pin_map.h"
    #include "driverlib/rom.h"
    #include "driverlib/sysctl.h"
    #include "driverlib/systick.h"
    #include "driverlib/uart.h"

    Hi,

    If diving a car too fast you may hit the traffic lights at the corner...

    Please observe what I said: add the file utils/uartstdio.c as symbolic link, not to inlude it like the .h file. Do not know how to do it? Better ask, or just copy both files to your project (take care how to do it).

    Also, what I said, was to read first the comments and functions; just jumping to UARTPrintf does not help, should init first with UARTStdioInit(comport) - again just read what can be comport  and do not forget to init the pins for that, if it is the case.
