title: What do you need to program a NXP SmartMX contactless MCU?
body: <p>I'm developing an authentication system with NFC technology with strong cryptographic functions.</p>
  
  <p>There are two solutions from NXP: Mifare DESFire EV1, which is a chip with memory areas and 3DES and AES128 crypt functions, and SmartMX2,which is a complete MCU that needs an OS and software to run.</p>
  
  <p>To choose between the two, I have to know how to program those tags. For what I've understood, the DESFire needs a USB reader/writer and the interface software, like this -->  <a href="http://www.mpsys.de/chipmanrfid_en.html" rel="nofollow">http://www.mpsys.de/chipmanrfid_en.html</a></p>
  
  <p>What equipment is needed to install the OS on a SmartMX card, and then debug? Is it possible to do it only via NFC interface?</p>
  
  <p>Thanks for your attention,
