title: How to print memory variable in U-boot?
body: <p>i have the following lines in my U-boot environment: </p>
  
  <pre><code>ram_crc=10e00000
  check_rd=if itest.l *$ram_crc == $crc_rd; then bootm $kernel; else run fail_h; fi
  </code></pre>
  
  <p>The comparison works. But how can i echo the contents of the memory address 10e00000?</p>
  
  <p>I tried to print in the failure handler:</p>
  
  <pre><code>set fail_h echo $ram_crc
  </code></pre>
  
  <p>but when i print the environment i can see that it has replaced the variable with the memory address:</p>
  
  <pre><code>fail_h=echo 10e00000
  </code></pre>
  
  <p>How can i print the contents of the memory address?</p>
  
  <p>Thanks!</p>
