• Using FlashPro header connected to BANK3 of PolarFire SoC
• On-board programmer (BANK 7)
The following is the block diagram for programming scheme of PolarFire SoC.

3.12 System Reset
DEVRST_N is an input-only reset pad that allows a full reset of the chip to be asserted at any time. The following
figure shows a sample reset circuit that uses a Microchip MCP121T-240E/TT device.
Figure 3-3. Reset Circuit
3.13 50 MHz Oscillator
A 50 MHz clock oscillator with an accuracy of ±10 ppm is available on the board. This clock oscillator is connected to
the FPGA fabric to provide a system reference clock.
The pin number of the 50 MHz oscillator is W12, and the pin name is HSIO92PB0/CLKIN_N_2/
CCC_NW_CLKIN_N_2/CCC_NW_PLL1_OUT0.

7. Appendix: Programming PolarFire SoC FPGA Using the On-Board
Programmer
The PolarFire SoC Icicle Kit includes an on-board programmer. An external programmer hardware is, therefore, not
required to program the PolarFire SoC device. The device can be programmed using the FlashPro software installed
on the host PC.
Follow these steps to program an on-board PolarFire SoC device using the on-board programmer.
Notes: The programming file will be available in a future release.
1. Connect the power supply cable to the J23 connector on the board.
2. Close Jumper J9 for mux U22.
3. Power on the board using the SW6 slide switch.
4. When the board is successfully set up, the power LEDs start glowing.
5. Download FlashPro Express from the following location: https://www.microsemi.com/product-directory/
programming/4977-flashpro#software
6. On the host PC, start the FlashPro Express software.
7. Click New Project to create a new project.
8. In the New Project window, do the following, and click OK.
• Enter a project name.
• Select Single device as the programming mode
9. Click Configure Device.
10. Click Program to program the device.
11. From the View Programmer pane, select the on-board FlashPro6 programmer.
12. Click Browse, and select the .stp file from the Load Programming File window.
The Programmer List window in the FlashPro Express software shows the programmer name, programmer type,
port, programmer status, and information about whether the programmer is enabled.
When the device is programmed successfully, a Run Program PASSED status is displayed.

Microchip Devices Code Protection Feature
Note the following details of the code protection feature on Microchip devices:
• Microchip products meet the specifications contained in their particular Microchip Data Sheet.
• Microchip believes that its family of products is secure when used in the intended manner and under normal
conditions.
• There are dishonest and possibly illegal methods being used in attempts to breach the code protection features
of the Microchip devices. We believe that these methods require using the Microchip products in a manner
outside the operating specifications contained in Microchip’s Data Sheets. Attempts to breach these code
protection features, most likely, cannot be accomplished without violating Microchip’s intellectual property rights.
• Microchip is willing to work with any customer who is concerned about the integrity of its code.
• Neither Microchip nor any other semiconductor manufacturer can guarantee the security of its code. Code
protection does not mean that we are guaranteeing the product is “unbreakable.” Code protection is constantly
evolving. We at Microchip are committed to continuously improving the code protection features of our products.
Attempts to break Microchip’s code protection feature may be a violation of the Digital Millennium Copyright Act.
If such acts allow unauthorized access to your software or other copyrighted work, you may have a right to sue
for relief under that Act.
