Setting Up the Demo Design

The following steps describe how to setup the demo design:
1. Connect the FlashPro4 programmer to the J5 connector of the SmartFusion2 Security Evaluation Kit
board.
2. Connect the jumpers on the SmartFusion2 Security Evaluation Kit board as shown in the following
table.
CAUTION: Switch OFF SW7 while connecting the jumpers.
