Application Note AC401January 20141© 2014 Microsemi Corporation SmartFusion2 SoC FPGA - SPI Master ProgrammingTable of ContentsPurposeThis application note describes how to use the serial peripheral interface (SPI) Master Programming mode on SmartFusion ®2 system-on-chip (SoC) field programmable gate array (FPGA) Development Kit board DVP-102-000400-001 Rev C.Note:Rev A and Rev B Development Kit Board are not supported.Two software utilities, SPI_Memory.exe and SetMuxes.exe, are described in this document. The SPI_Memory.exe is used to program Atmel ® AT25DF641 and SetMuxes.exe is used to configure the multiplexers on the Development Kit board to either perform SPI Memory Programming or initiate SPI Master Programming.IntroductionSPI Master Programming mode, also known as auto-update or reflash is one of the programming methods available to program SmartFusion2 devices. Refer to the SmartFusion2 Programming User's Guide for more information on the available programming modes. On power-up or resetting the device with FLASH_GOLDEN_N pin asserted (driven low), the SmartFusion2 device configures the dedicated SPI port to operate in Master mode. It also reads the attached external SPI memory device from address zero. Auto programming is executed if a valid programming image is found. Figure 1 shows a high level system design to execute auto programming.Purpose . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 1Introduction . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 1Development Kit Board Programming Circuit Design Description . . . . . . . . . . . . . . . . . . . . 2Programming the SPI Master . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 4List of Changes . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 6Appendix A - SPI Memory Utility . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 7Appendix B - SetMuxes Utility . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 7SmartFusion2 SoC FPGA - SPI Master Programming2Development Kit Board Programming Circuit Design DescriptionThe Development Kit board programming circuitry has an on board FT4232H module from Future Technology Devices International (FTDI). This module is a universal serial bus (USB)-to-serial interface converter. For more information on FT432H module, see FTDI website at /Products/Modules/DevelopmentModules.htm. This module is connected to the M2S dedicated SPI port and the SPI memory device using the multiplexers. The multiplexers can then be configured either manually or through SetMuxes.exe utility described below to program the Atmel SPI memory device or to initiate an auto-programming operation. The Development Kit board is designed in this fashion to program the SPI memory device on board through the FTDI chip.

If possible, disconnect all powercables from the existing system before you add a device.• Before connecting or removing signal cables from the motherboard, ensure that all power cables are unplugged.• Seek professional assistance before using an adapter or extension cord. These devices couldinterrupt the grounding circuit.• Make sure that your power supply is set to the correct voltage in your area. If you are not sure about the voltage of the electrical outlet you are using, contact your local power company.• If your power supply is not functioning, do not attempt to repair it. Contact a qualified servicetechnician or your retailer.OPERATIONAL SAFETY• Before installing the carrier card or connecting devices to it, carefully read any and all providedmanuals for the devices in question.• Before using the product, make sure all cables are correctly connected and the power cables arenot damaged. If you find any damage, contact your dealer immediately.• To avoid short circuits, keep paper clips, screws, staples, and other foreign metallic objects awayfrom connectors, slots, sockets and circuitry.• Avoid dust, humidity, and temperature extremes. Do not locate the product in any area where it may become wet or damp.• Place the product on a stable surface at all times.• If you encounter technical problems with the product, contact a qualified service technician or your retailer.NoticesFEDERAL COMMUNICATIONS COMMISSION STATEMENTThis device complies with Part 15 of the FCC Rules. Operation is subject to thefollowing two conditions:• This device may not cause harmful interference, and• This device must accept any interference received including interference thatmay cause undesired operation.This equipment has been tested and found to comply with the limits for a ClassB digital device, pursuant to Part 15 of the FCC Rules. These limits are designedto provide reasonable protection against harmful interference in a residentialinstallation. This equipment generates, uses and can radiate radio frequency energyand, if not installed and used in accordance with manufacturer’s instructions, maycause harmful interference to radio communications. However, there is no guaranteethat interference will not occur in a particular installation. If this equipment doescause harmful interference to radio or television reception, which can be determinedby turning the equipment off and on, the user is encouraged to try to correct theinterference by one or more of the following measures:• Reorient or relocate the receiving antenna.• Increase the separation between the equipment and receiver.• Connect the equipment to an outlet on a circuit different from that to which thereceiver is connected.• Consult the dealer or an experienced radio/TV technician for help.ENVIRONMENTAL DISPOSAL STATEMENTSDO NOT throw the system or its components in municipal waste. This product has been designed to enable proper reuse of parts and recycling. This symbol of the crossed out wheeled bin indicates that the product (electrical and electronic equipment) should not be placed in municipal waste. Check local regulations for disposal of electronic products.DO NOT throw the mercury-containing button cell battery in municipal waste.

Multiple modules may be connected together for enhanced functionality, using the on-board SERDES links. The AT1PEC1 carrier card allows up to two modules to be installed, although most on-card features will function with only the first module installed.Illustration 1: Arctic Tern Block DiagramIllustration 2: Arctic Tern Dual Module PCIe Carrier Block DiagramModule Installation and RemovalMODULE INSERTIONModules are inserted at an angle, then rotated downward into the socket latches in the same manner as standard SODIMM memory modules. Module 1 must be installed before Module 2 (if applicable) due to mechanical interference between the two modules during the installation process.To install, first gently insert the module at an approximate 45 degree angle to the carrier card as shown. The module must be fully inserted to the hard stop, otherwise it will not latch during the second part of the installation process.Once inserted, carefully but firmly press the module flat toward the carrier card. Use your thumbs and press on the upper two corners of the module during this process. Installation is complete once the latches engage and the module no longer attempts to return to an angled position away from the carrier card.MODULE REMOVALModules must be removed in the reverse order to installation. Module 2 must be removed before Module 1 due to mechanical interference between the two modules during the removal process.To remove, gently spread the two black plastic socket latches on either side of the module until the module “pops” up and sits at an angle to the carrier card. Once the module is at an angle to the carrier card, grasp the module by the two short edges and gently but firmly pull the module directly away from the socket until it releases from the carrier card.CAUTION: Attempting to over-rotate or otherwise mechanically force the module away from the carrier card can result in damage to the socket and/or module. Damage caused by improper installation or removal is not covered under warranty.Headers and ConnectorsPIN NUMBERING CONVENTIONSAll headers on the AT1PEC1 follow a standard layout, with pin 1 being denoted with a white silkscreen marking. Dual row headers follow the numbering convention shown above, where all even pins are on one side of the header and all odd pins are on the other. Single row headers use a monotonically increasing pin number, starting from pin 1. Key pins are not physically present, but are still counted as pins in the numbering scheme.Illustration 3: Dual Row Header with Annotated Pins, Marker, and KeyRTC BACKUP BATTERY SOCKET376 / 377 Coin
