Xilinx FPGA_as_a_Service之Xilinx Base Runtime指令碼分析

參照[Xilinx FPGA_as_a_Service 概述](https://feishujun.blog.csdn.net/article/details/107910624) 的安裝流程，本篇部落格對Xilinx Base Runtime指令碼進行分析。第一個指令碼是在宿主機中執行的host_setup.sh。指令碼的主要用途是按照XRT和重新整理Shell。看其中的usage函數，列出了指令碼參數的使用，如下：

./host_setup.sh --version <version>
./host_setup.sh  -v       <version>
<version>        : 2018.3 / 2019.1 / 2019.2 / 2020.1
--skip-xrt-install    : skip install XRT
--skip-shell-flash    : skip flash Shell
--install-docker      : install docker service

比如Install 2019.2 XRT and flash Shell的命令如下：./host_setup.sh -v 2019.2
