ADALM-PlutoSDR 上手（二）--Firmware 编译

1.下载plutosdr-fw和相关的源码包，参考plutosdr-fw-0.27 的.gitmodules里面的路径和 branch下载，之前由于下载的源码branch不对，折腾了一周编译也没有通过：
我这里用的plutosdr-fw-0.27 的版本，.gitmodules源码路径和branch如下，不同的版本对应的branch不同。

[submodule "u-boot-xlnx"]
    path = u-boot-xlnx
    url = https://github.com/analogdevicesinc/u-boot-xlnx.git
    branch = pluto
[submodule "buildroot"]
    path = buildroot
    url = https://github.com/analogdevicesinc/buildroot.git
    branch = pluto
[submodule "linux"]
    path = linux
    url = https://github.com/analogdevicesinc/linux
    branch = xcomm_zynq
[submodule "hdl"]
    path = hdl
    url = https://github.com/analogdevicesinc/hdl
    branch = hdl_2017_r1

这里写图片描述
2.把几个源码包解压，放入plutosdr-fw-0.27目录下的buildroot，hdl，linux，u-boot-xlnx目录。注意文件夹的名字。

3.参考Readne.md文件顺序执行命令，安装相应的工具和配置编译器的路径，我这里的用的Vivado2015.4

* Build Instructions
 ```bash
      sudo apt-get install git build-essential fakeroot libncurses5-dev libssl-dev ccache 
      sudo apt-get install dfu-util u-boot-tools device-tree-compiler libssl1.0-dev mtools
      git clone --recursive https://github.com/analogdevicesinc/plutosdr-fw.git
      cd plutosdr-fw
      export CROSS_COMPILE=arm-xilinx-linux-gnueabi-
      export PATH=$PATH:/home/chris/pluto/Xilinx/SDK/2015.4/gnu/arm/lin/bin
      export VIVADO_SETTINGS=/home/chris/pluto/Xilinx/Vivado/2015.4/settings65.sh
      make

 ```

sudo apt-get install dfu-util u-boot-tools device-tree-compiler libssl1.0-dev mtools 报错

chris@chris-ubuntu:~/pluto/source/plutosdr-fw-master$ sudo apt-get install dfu-util u-boot-tools device-tree-compiler libssl1.0-dev mtools

暂时没管继续。

配置环境变量，注意Vivado的安装路径和版本

export CROSS_COMPILE=arm-xilinx-linux-gnueabi-
export PATH=$PATH:/home/chris/pluto/Xilinx/SDK/2015.4/gnu/arm/lin/bin
export VIVADO_SETTINGS=/home/chris/pluto/Xilinx/Vivado/2015.4/settings64.sh

4.make，编译u-boot和kernel和buildroot等等。

4.1 u-boot正常编译通过；
4.2 kernel编译的时候提示文件找不到，进入相应的目录下查看确实没有相关文件，但是在压缩包里面是有的，直接把压缩包里面的再copy一份到相应的目录即可。
4.3编译buildroot，
