title: Upload firmware from Flash using U-Boot
body: <p>I have a problem. My system is an embedded Linux plaform. I am connecting to my board using serial port and I can access U-Boot.</p>
  
  <p>I need to extract the complete firmware residing in flash through the console or through Ethernet. It looks like downloading is easy using TFTP or serial (Kermit, etc), but uploading it to the host PC for backup isn't obvious.</p>
  
  <p>Does anyone know how this can be done?</p>
