title: What is different between u-boot.bin and u-boot.img
body: <p>I just compiled the U-Boot bootloader and I see a few file names in the u-boot program directory which are:</p>
  
  <pre><code>u-boot.bin
  u-boot.img
  u-boot.lds
  u-boot.srec
  </code></pre>
  
  <p>Basically, I'm interested in the files with extensions <code>.img</code> and <code>.bin</code>. What is different between them?
  Is <code>u-boot.img</code> for SD card and <code>u-boot.bin</code> for flashing to NAND ?</p>
