title: How to get to menuconfig for u-boot in Yocto environment
body: <p>I'm using Yocto for the first time for an ARM embedded system with a Xilinx Zynq.
  I want to make some configuration changes that requires going in the menuconfig utility. Yocto documentation shows how to do it for the Linux Kernel</p>
  
  <pre><code>bitbake yocto-xlnx -c menuconfig
  </code></pre>
  
  <p>Which, for Xilinx,  I turned into</p>
  
  <pre><code>bitbake linux-xlnx -c menuconfig
  </code></pre>
  
  <p>It works very well. </p>
  
  <p>Now, I want to do the same with u-boot and change the .config file using the menuconfig utility. I can't find any way to do it in Yocto or Xilinx documentation. I tried the obvious like</p>
  
  <pre><code>bitbake u-boot-xlnx -c menuconfig
  </code></pre>
  
  <p>just to get an error message:</p>
  
  <p>ERROR: Task do_menuconfig does not exist for target u-boot-xlnx</p>
  
  <p>Any Idea how to get to u-boot menuconfig with Yocto?</p>
  
  <p>Edit:
  here are the layers I use</p>
