Introduction

This page provides details related to the standalone axis switch driver. This driver supports resetps Zynq Ultrascale+ MPSoC and Microblaze .

Driver Sources

The source code for the driver is included with the Vitis Unified Software Platform installation, as well as being available in the Xilinx Github repository.

Driver Name	Path in Vitis	Path in Github

Driver Name	Path in Vitis	Path in Github
axis_switch	<Vitis Install Directory>/data/embedded/XilinxProcessorIPLib/drivers/axix_switch	https://github.com/Xilinx/embeddedsw/tree/master/XilinxProcessorIPLib/drivers/axis_switch

Note: To view the sources for a particular release, use the rel-version tag in github. For example, for the 2020.1 release, the proper version of the code is: https://github.com/Xilinx/embeddedsw/tree/xilinx_v2021.1/XilinxProcessorIPLib/drivers/axis_switch

The driver source code is organized into different folders. The table below shows the axis_switch driver source organization.

Directory	Description

Directory	Description
doc	Provides the API and data structure details
data	Driver .tcl, .mdd and .yaml file
examples	Example applications that show how to use the driver features
src	Driver source files, make and cmakelists file

Note: AMD Xilinx embeddedsw build flow is changed from 2023.2 release to adapt to the new system device tree based flow. For further information, refer to the wiki page Porting embeddedsw components to system device tree (SDT) based flow - Xilinx Wiki - Confluence (atlassian.net).

The .yaml(in data folder) and CMakeLists.txt(in src folder) files are needed for the System Device Tree based flow. The Driver .tcl and .mdd files are for the older build flow which will be deprecated in the future.
