Vitis Drivers API Documentation

This file demonstrates how to use xsrio driver on the Xilinx SRIO Gen2 Core.
The SRIO Gen2 comprised of phy, logical and transport and buffer layers. Using this IP We can generate both messaging and read/write semantics.
This example demonstartes how to generate SWRITE(Streaming Write) transactions on the core.
Inorder to test this example external loopback is required at the boardlevel Between the SRIO Tx and Rx pins.
H/W Requirments: Inorder to test this example at the h/w level the the SRIO Initiator Request is connected to the AXI DMA MM2S Channel and SRIO Target Request is connected to the AXI DMA S2MM Channel.
S/W Flow: 1) The system consists of two different memories.Processor runs this example Code in one memory and the SRIO packet is formed in another memory. 2) The SRIO Packet is framed in the Memory 3) Configure the AXI DMA MM2S source address and S2MM for Destiantion address and specify the byte count for both the channels and then start the dma. 4) Compare the Data.
MODIFICATION HISTORY:
Ver Who Date Changes ----- ---- -------- ------------------------------------------------------- 1.0 adk 16/04/14 Initial release 1.1 ms 01/23/17 Modified 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.

XSrioDmaLoopbackExample This function does a minimal test on the XSrio device and driver as a design example.
The purpose of this function is to illustrate how to use the XSrio Component.
This function does the following:
InstancePtr | is a pointer to the instance of the XSrio driver. |
DeviceId | is Device ID of the SRIO Gen2 Device. |
