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.
