title: IAR: Differences between a debug probe and a trace probe
body: <p>I am currently entering in the wonderfull world of embedded programming. I have a big port project. I have to port a firmware (which sources are in a bad state) from an ARMv4T (ARM7TDMI) to an ARMv7-M (ARM Cortex-M3).</p>
  
  <p>Right, so I'm getting started with the IAR IDE. For debugging, I knew that hardware debug probe exists, but my getting started guide also mention trace probe. As I love having everythings in control, I wonder <strong>what are the differences between debug probe and trace probe</strong>.</p>
  
  <p>I've googled it but "debug" "probe" and "trace" are too big keywords to find an explanation instead of commercial site.. I've seen that trace probe contains much more memory than a debug probe (that goes from a few MB to more than 1GB o_O ).</p>
