The instructions of creating an AMP example design with PetaLinux tools

Xapp1078 Instructions for Vivado 2014.4

NOTE: The zedBoard flow has not been verified

Note: This xapp requires using a Linux host to compile the embedded Linux kernel. The instructions have been setup such that all implementation work will be done in a directory called xapp1078_2014.4/design and all linux work will be done in a directory called xapp1078_2014.4/plnx-project. The instructions will require files to be copied between xapp1078_2014.4/design and xapp1078_2014.4/plnx-project so if the Vivado and SDK tools are ran on a Windows machine, the files will need to be copied from the Windows xapp1078_2014.4/design to the Linux machine's xapp1078_2014.4/plnx-project.
