title: Minimum configuration to run embedded Linux on an ARM processor?
body: <p>I need to produce an embedded ARM design that has requirements to do many things that embedded Linux would do. However the design is cost sensitive and does not need huge amounts of horse power. Mostly will be talking to serial interfaces. Ideally I would like to use one of the low end ARMs. What is the lowest configuration of an ARM that you have successfully used embedded Linux on. </p>
  
  <p>Edit:</p>
  
  <p>The application needs a file system on some kind of flash device and the ability to run applications for processing the data. Some of the applications might be written by others than myself. I also need to ability to load new applications or update old apps using the serial ports to accept the apps. </p>
  
  <p>When I have looked at other embedded OSes they seem to be more of a real time threading solution than having the ability to run applications. I am open to what ever will get the job done.</p>
