README ====== This README file discusses the port of NuttX to the MT-DB-X3 development board from MattairTech. This board may host a variety of 64-pin AVR XMega part. This port was specifically performed using the ATXmega384c3. See the MattairTech website for further information about the MT-DB-X3: http://www.mattairtech.com/. NOTE: There is no port for the XMEGA in place as of this writing. At this point in time, this README file is only a repository for pre-porting information. It is not clear as of this writing whether there ever will be a port to the MT-DB-X3 development board or not.
