title: ARM scatter file symbols not defined?
body: <p>In my scatter file, I have a memory region named TCM_COPY,</p>
  
  <p>In my C file, i am trying to extern the region_name like, </p>
  
  <p>extern unsigned int Image$$TCM_COPY$$Base.</p>
  
  <p>But when I compile that C file, the ARM compiler generates an error;</p>
  
  <p>L6218E: Undefined symbol Image$$TCM_COPY$$Base.</p>
  
  <p>I am wonder why I can't import that region symbol from my scatter file??</p>
