I am using the stm32h745-Discovery board.I am getting the data using the interrupt method and polling method but am not able to get the Data using the uart_receive_DMA. …

It's in the CubeH7 package, typically downloaded and unpacked into a repository by the Cube tools.

Or simply unpacked as a .ZIP into a local directory on your machine.
