petalinux 自动构建脚本

使用xilinx的petalinux构建BOOT.BIN和image.ub需要输入多条指令, 每次都这样输入的话真的会累死人, 所以想到把指令写成脚本, 一劳永逸。

# fpga 导出的hdf和bit文件的存放目录
hdf_file_dir=/samba/fpga_hdf_and_bit
# petalinux的安装目录

# 板级支持包
board_support_package="/opt/board_support_package/xilinx-zcu102-v2017.4-final.bsp"

# Auto build linux image for zcu102/zcu104 board
