    Can you determine if the problem is hardware or software? Is the data corrupted on the transmission line, or perhaps the data is not received properly because the interrupt did not respond in time and you overflowed the hardware FIFO. You might want to start with a more simple example such as using the TivaWare example: C:\ti\TivaWare_C_Series-2.1.4.178\examples\boards\ek-tm4c1294xl\uart_echo to verify that the hardware is working. You also may find it easier to use TI-RTOS instead of FREE-RTOS as there are already examples created for you EK-TM4C129XL Launchpad such as: C:\ti\tirtos_tivac_2_16_01_14\tirtos_tivac_2_16_01_14_examples\TI\EK_TM4C1294XL\uartechodma
