xaxipcie_ep_enable_example.c File Reference

Overview

This file contains a design example for using AXI PCIe IP and its driver.

The example handles AXI PCIe IP when it is configured as an end point. It shows how to use the API's.

Note

This code will illustrate how the AXI Pcie IP and its standalone driver can be used to:

• Initialize a AXI PCIe bridge core built as an end point
• Retrieve root complex configuration assigned to end point

We tried to use as much of the driver's API calls as possible to show the reader how each call could be used and that probably made the example not the shortest way of doing the tasks shown as they could be done.

  1.00a rkv  03/07/11 Initial version based on PLB PCIE example
  2.00a rkv  10/19/11 Renamed function call XAxiPcie_GetRequestId to
                      XAxiPcie_GetRequesterId
  3.1   ms   01/23/17 Added xil_printf statement in main function to
                      ensure that "Successfully ran" and "Failed" strings
                      are available in all examples. This is a fix for
                      CR-965028.
        ms   04/05/17 Added tabspace for return statements in functions
                      for proper documentation while generating doxygen.
