每个文件单独下载：
mkdir fpga_images
#Example for>UHD 3.11.x.x.
$ wget http://files.ettus.com/binaries/cache/x3xx/fpga-494ae8bb/x3xx_x310_fpga_defaultg494ae8bb.zip
下载之后解压到同一个文件夹下：
mkdir ~/images #最后解压完的文件都在这里
cd fpga_images
unzip -o '*.zip' -d ~/images
接下来，在UHD安装前缀中创建images/文件夹。
cd /usr/local/share/uhd/
mkdir images
cd images
将上面解压缩的FPGA映像复制到对应的位置。
sudo cp -v ~/images/* .
