How to use another UART channel on DK-TM4C129X

So far I've used the default UART0 available through USB/ICDI. Now I would like to use UART to communicate with another microcontroller board.
I've tried to read through the user guide to understand where the Rx Tx connection should go, but with no luck.

The documentation seems to be a tad bit complicated for my level of understanding. Could anyone please give me some information of how to setup hardware (which pins to connect, which jumper to short) and software (Appropriate configuration in CC Studio). Any pointers in the right directly is highly appreciated.

Also, I did not find any step by step tutorials for this board ? Now, I am wondering is this board targeted towards experts ?

Thanks

    Hello,

    From the software point of view, the initialization/setup will be the same as for UART0 with exception the base address will be changed to correlate to the UART you plan to use.

    In regard to HW hookup, have you reviewed the DK board documentation (www.ti.com/.../spmu360.pdf) to see which connector pins have an alternate UART brought out from the device? For example reviewing the document I see in section 2.1.8.1 that UART5 Rx and Tx are brought to J29-A pins 3 and 4.

    As far as step by step tutorials, we target the launchpads for these trainings due to the lower cost/easier access to them. The DK boards do tend to be more feature rich and, as such, more complex; however, many of the tutorials can also be applied to the DK in most cases. We also have many examples and documentation that is included in TivaWare that is specifically targeted at the DK boards. If doing a tutorial, it is worth looking in TivaWare to see if we have the specific tutorial example also available for the DK.
