Overview

This file contains the example using XZDma driver to do simple data transfer in Normal mode on ZDMA device for 1MB data transfer.

MODIFICATION HISTORY:

Ver   Who     Date     Changes



1.0   vns     2/27/15  First release
      vns    10/13/15  Declared static array rather than hard code memory.
      ms     04/05/17  Modified comment lines notation in functions to
                       avoid unnecessary description to get displayed
                       while generating doxygen.
1.3   mus    08/14/17  Do not perform cache operations if CCI is enabled
1.4   adk    11/02/17  Updated example to fix compilation errors for IAR
                 compiler.
1.5   adk    11/22/17  Added peripheral test app support.
        12/11/17 Fixed peripheral test app generation issues when dma
                 buffers are configured on OCM memory(CR#990806).
        18/01/18 Remove unnecessary column in XIntc_Connect() API.
        01/02/18 Added support for error handling.
1.7   adk    21/03/19  Fix alignment pragmas in the example for IAR compiler.
             19/04/19  Rename the dma buffers to avoid peripheral
                 test compilation errors with armclang compiler.
1.12    sk      02/16/21 Add the documentation for XZDma_SimpleExample()
                 function parameters to fix the doxygen warning.
1.13  asa     08/24/21 Make changes to add a missing data invalidation
                       operation just before the destination buffer data is
                       being read.
                       Changes were done for other cleanups and also to
                       ensure that the DMA is reset before the program exits.
1.16  sa     09/29/22  Fix infinite loops in the example.

int XZDma_SimpleExample	(	XZDma *	ZdmaInstPtr,
		UINTPTR	BaseAddress
	)

This function does a test of the data transfer in simple mode of normal mode on the ZDMA driver.

Parameters

ZdmaInstPtr	contains a pointer to the ZDMA instance which is going to be connected to the interrupt controller.
BaseAddress	contains the base address of the ZDMA device

Returns
