title: 'fastboot boot' command doesn't work?
body: <p>I have compiled my kernel and I want to test it.</p>
  
  <p>I used</p>
  
  <pre><code>fastboot boot zImage
  </code></pre>
  
  <p>but this command booted my old kernel. Why?</p>
  
  <p>I have created and flashed boot.img with ramdisk from old kernel, but it doesn't boot. Is there any way to debug boot process without UART?</p>
  
  <p>Greetings, Michal.</p>
  
  <p>Edit:</p>
  
  <p>I found solution. Before executing boot command, first I have to execute erase boot.</p>
  
  <p>But I get boot loop :( Is there any way to read logs when I can't boot?</p>
  
  <p>I really would like to make this kernel bootable. I will be glad for any suggestions.</p>
