title: How to import a big project to xilinx SDK and generate .elf?
body: <p>I'm very new to zedboard.</p>
  
  <p>I have a big project, which has several hierarchical makefiles. I want to import the project into xilinx SDK, build it, and generate the elf file, and load it to Zedboard zynq 7000 xc7z020clg484. Or, load the project into the ARM memory, build it, and execute it.  </p>
  
  <p>I tried import->existing project, but it seems doesn't work. I still can't build it. </p>
  
  <p>Is there any way I can do this?</p>
