Microsemi SmartFusion2 - How to Use Envm; Data Storage in Envm Using the Libero Envm Client

Embedded NVM (eNVM) Controllers
UG0331 User Guide Revision 15.0 165
Notes:
• Refer to UG0443: SmartFusion2 SoC FPGA and IGLOO2 FPGA Security and Reliability User Guide
for more information on the certificates, key codes, and digests.
• The system controller performs read/write operations on unreserved eNVM pages using system
controller services. It only reads data from reserved eNVM pages.
5.4 How to Use eNVM
This section describes how to use the eNVM in the SmartFusion2 devices. To configure the
SmartFusion2 device features and then build a complete system, use the System Builder graphical
design wizard in the Libero SoC software.
5.4.1 Data Storage in eNVM Using the Libero eNVM Client
The Libero eNVM client creates the eNVM data that the FlashPro software uses to initialize the eNVM
during programming. The programmed eNVM can be accessed by the Cortex-M3 processor, HPDMA,
PDMA, or the FPGA fabric master connected to the AHB bus matrix.
The following figure shows the initial System Builder window where the required device features can be
selected. For details on how to launch the System Builder wizard and detailed information on how to
use it, refer to SmartFusion2 System Builder User Guide.
