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.
