背景

工程师可能同时使用多个Vivado工程，以便测试不同的硬件配置。所以需要让一个PetaLinux工程支持多个Vivado工程。

Vivado工程更改后，PetaLinux工程需要更新HDF文件。另外最好在PetaLinux工程里记录使用的所有硬件相关文件，比如bit、HDF文件等。以便将来检查对应的硬件设计。

下面是一个脚本，可以自动备份以前的硬件相关文件，再从Vivado工程取得最新的硬件相关文件；并且执行命令，让PetaLinux工程更新HDF文件。脚本需要两个参数，第一个是Vivado工程的名字，第二个是Vivado工程的目录。

使用这个脚本，可以更方便的让一个PetaLinux工程，支持多个Vivado工程。

# Engineer may have several Vivado project that has same name.
# But each project may have different configuration.
# So each project is located in different directory.
# For example, there are three hardware Description directory:
#       hardwareDescription_v1; 
#       hardwareDescription_v2; 
#       vivado_project/xx.sdk;
# You can use following command to swith the hardware platform for petalinx project:
#       peta-update-hdf.sh petalinux_Project hardwareDescription_v1
#       peta-update-hdf.sh petalinux_Project hardwareDescription_v2
#       ...
#       peta-update-hdf.sh petalinux_Project vivado_project/xx.sdk
#       peta-update-hdf.sh petalinux_Project petalinux_Project/backup/hdf-xx
