Step 1 – Download Firmware Drivers
In order to use the Firmware drivers and sample projects for SmartFusion2 it is necessary to download them from the online Repositories into the IP vault on your machine.
1.Open the Microsemi SoC Firmware catalog (Start > Programs > Microsemi Libero SoC v11.0 > Firmware Catalog
v11.0 > Firmware Catalog.
2.Look for the message New cores are available for download at the bottom of the Firmware Catalog.
Figure 2 - New cores message in the Firmware catalog
3.Click on Download them now to download all the most recent drivers for peripherals including Sample code and
CMSIS compliant HAL etc. The resulting window should look like the figure below.

Opening SmartFusion2_Simple_MSS_MSS_0 in SmartDesign
8.The SmartDesign canvas will open with the SmartFusion2_Simple_MSS_ MSS_0 component visible.
Figure 7 – SmartFusion2 MSS in SmartDesign canvas
9.Double-click SmartFusion2_Simple_MSS_MSS_0 to open the SmartFusion2 MSS configurator. The MSS configurator
will appear as shown in the figure below.
Figure 8 - SmartFusion2 MSS configurator
MSS peripherals that can be disabled have a small wrench symbol and check box in the lower right corner. To disable a peripheral, select the peripheral, right-click, and select Disable, or click on the checkbox. The peripheral turns grey to indicate a peripheral has been disabled. Disabled peripherals can be enabled by repeating the procedure.
10.Disable all of the peripherals that have a checkbox except MMUART_0. Enable the GPIO peripheral.
Tip: click View > Maximize Work Area or the Maximize/Restore Work Area button () on the toolbar to expand the working area while using the SmartFusion2 MSS configurator to configure the MSS peripherals.
Next configure the GPIO block. For this design we will configure GPIO[1:0] as outputs and GPIO[8] as an input.
GPIO[1:0] will be connected to LEDs on the SmartFusion2 starter kit; GPIO[8] will be connected to a switch on the SmartFusion2 starter kit, the GPIOs are brought out to the fabric to match the connections on the SmartFusion2 starter kit board.
11.Configure the MSS GPIO block by double-clicking the GPIO in the MSS configurator. Configure the GPIOs as shown
below.
?Set/Reset Definition: accept default settings
?Configure GPIO[1:0] and GPIO_[8] per the table below:
Figure 9 - SmartFusion2 GPIO Configuration 12.Click OK to close the GPIO configurator.
13.Double-click the MSS_CCC box in the SmartFusion2 MSS configurator. Enter the following in the CCC configurator:
?CLK_BASE: 100 MHz
?Monitor FPGA Fabric PLL Lock: checked
?M3_CLK: 100 MHz
?APB_0_CLK: M3_CLK / 4 (25 MHz)
? APB_1_CLK: M3_CLK / 4 (25 MHz)
The APB bus clock rate of 25 MHz was selected to match the rates used in the sample firmware projects that will be generated later.

14.Click OK to close the CCC configurator.
15.After configuring the GPIO block the MSS configurator should appear as shown in the figure below.
Figure 11 - SmartFusion2 MSS configurator after configuring GPIOs and Reset
16.Save the SmartFusion2_Simple_MSS_MSS component (File > Save SmartFusion2_Simple_MSS_MSS).
17.Close the SmartFusion2 MSS configurator (File > Close SmartFusion2_Simple_MSS_MSS).
18.If necessary, restore the work area (View > Restore Work Area).
19.Select the SmartFusion2_Simple_MSS tab. The SmartFusion2 component (SmartFusion2_Simple_MSS_MSS_0) will
be visible in the SmartDesign canvas. The warning symbol () indicates that the SmartFusion2 component has changed. Right click and select Update Instance(s) with Latest Component. The SmartDesign canvas will resemble the figure below.
Figure 12 - SmartDesign canvas with SmartFusion2 MSS component
Next you will add the SmartFusion2 Chip Oscillator and fabric CCC components to the SmartDesign canvas and connect them SmartFusion2 MSS component.
20.Expand the Clock & Management category in the Libero SoC IP Catalog.
Figure 13 - Libero SoC IP Catalog
21.Drag an instance of Chip Oscillators v1.0.100 onto the SmartDesign canvas. If the component appears shadowed in
the Vault, right-click the name and select Download.
22.Drag an instance of Clock Conditioning Circuitry (CCC) v2.0.100 onto the SmartDesign canvas. The canvas will appear
as shown in the figure below.
Figure 14 - SmartDesign canvas after adding OSC and CCC components
23.Double-click the OSC_0 component in the SmartDesign canvas to open the SmartFusion2 Chip Oscillators
configurator.
24.For this design we will use the On-chip 25/50 MHz RC Oscillator. Configure the Oscillator as follows:
?On Chip 25/50 MHz RC Oscillator: checked
?Drives Fabric (CCCs): checked
?Drives Fabric Logic: un-checked
Figure 15 - On-chip RC oscillator configuration
25.Click OK to close the Chip Oscillators Configurator.
26.Double-click the FCCC_0 component in the SmartDesign canvas to open the SmartFusion2 Fabric CCC configurator.
27.Select the Basic tab in the FAB CCC configurator. Enter the following then click OK:
?Reference clock: Select 25/50 MHz Oscillator from the pull-down menu
?PLL Analog Supply voltage: 3.3V
? GL0: checked; Frequency = 100 MHz
Figure 16 - selecting the FAB CCC reference clock
The PLL Analog Supply voltage can be either 2.5V or 3.3V. The voltage setting in the configurator must match the PLL Analog Supply voltage on the board to ensure the PLL works correctly. The PLL Analog Supply voltage is tied to 3.3V on the SmartFusion2 Starter kit, so the setting must be changed in the FAB CCC configurator above.
28.Click OK to close the FAB CCC configurator. The SmartDesign canvas will appear as shown in the figure below.
