新建Petalinux工程：
petalinux-create -t project --template zynq -n <NAME>
导入vivado hdf文件：
petalinux-config --get-hw-description=<hdf所在目录>
打包启动镜像：
petalinux-package --boot --fsbl --fpga --uboot --force

sudo tar -zxvf rootfs.tar.gz -C /media/sunlee/rootfs/

更换hdf文件后重新生成设备树：
petalinux-config -c device-tree
将工程打包为BSP文件：
petalinux-package --bsp -p <plnx-proj-root> \ --hwsource <hw-project-root> --output MY.BSP
根据BSP文件新建petalinux工程：
petalinux-create -t project -s ./BSP0.bsp
