    Hi,

      You created your drivers. Is there any reason why you would not use TivaWare that is a free library of peripheral drivers, examples, tools for your development. We can only support TivaWare library, not some custom drivers. You can download the latest TivaWare from https://www.ti.com/tool/SW-TM4C. Please refer to the uDMA example at C:\ti\TivaWare_C_Series-2.2.0.295\examples\boards\ek-tm4c1294xl\udma_demo in TivaWare library. This example demonstrates uDMA for UART transfers.
