【工程师分享】自动删除Xilinx的SDK/Vitis下软件(驱动程序)的旧版本的Linux脚本,便于Source Insight查看Xilinx的软件代码

作者: HankFu,本文转载自:博客园

Xilinx的开发工具SDK/Vitis都可以自动根据Vivado设计,创建软件工程,自动配置各个外部设备的驱动程序。为了兼容旧版本工程,SDK/Vitis里提供了多个IP版本的驱动程序。如果在SDK/Vitis的软件工程里查看代码,驱动程序都是正确的。

如果没有工程,也可以在安装目录下查看代码,比如目录Vitis\2020.2\data\embeddedsw\XilinxProcessorIPLib\drivers。这时候,需要自己选择对应的版本。

第三方源代码编辑器,比如Source Insight,可以创建自己的工程,查找所有符号表等。由于有多个IP版本的驱动程序,只能手动添加对应IP的驱动,到Source Insight工程。否则Source Insight能找到函数的多个实现,看起来有些麻烦。SDK/Vitis下大约有200个软件模块,全部手动添加的话,比较麻烦。

为了避免上述情况,可以把旧版本的驱动程序删除。手动删除旧版本,也比较繁琐,也容易出错。犹豫很久后,终于写了一个Linux脚本,自动删除SDK/Vitis下驱动程序的旧版本。当然,在删除之前,请做好备份。万一需要的情况下,需要恢复。如果是Linux环境,可以直接执行这个Linux脚本;如果是Windows环境,可以借助WSL执行。 SDK/Vitis在下列目录,有多个版本的驱动。 请在下列目录执行脚本。

Vitis/2020.2/data/embeddedsw/XilinxProcessorIPLib/drivers
Vitis/2020.2/data/embeddedsw/ThirdParty/sw_services
Vitis/2020.2/data/embeddedsw/ThirdParty/bsp
Vitis/2020.2/data/embeddedsw/ThirdParty/sw_services
Vitis/2020.2/data/embeddedsw/lib/sw_services 
Vitis/2020.2/data/embeddedsw/lib/bsp

脚本如下:
