Hi,

I am using TI RTOS TM4C1294 EVM board, Where I can find low level function calls for udma memory to memory transfer of data.

    Manohar,

    On TI RTOS, the use of dma is typically "embedded" in the peripheral drivers. For example, if using UART, you can use the TI-RTOS UART Driver and enable (or not) DMA.
    - See UART Driver on chapter 5.12 of TI-RTOS Users_Guide.pdf

    For independent DMA usage (are you talking about internal memory to internal memory?), you can use the standard Tivaware DMA API's.
    - See chapter 31 on Tivaware Driverlib User Guide.
