    In critical applications, an upset in the JTAG circuit could lead to an undesired JTAG state. In such cases, Microsemi recommends tying off TRSTB to GND through a resistor placed close to the FPGA pin. Available only in SmartFusion2.

  • Page 20: Design Implementation

    The TDO pin of the JTAG header represents the beginning of the chain and the TDI pin of the last device is connected back to the JTAG header. While programming any Microsemi device in the chain, the Libero SoC (or standalone FlashPro) software puts non-Microsemi devices in the chain into bypass mode. Once a device is in bypass mode, its data register length becomes one and does not react to any programming instructions given by the programmer.

  • Page 21: Programming Using An External Programmer

    Normal device operation as well as the specification for the JTAG signals SmartFusion2 and IGLOO2 FPGAs require a single programming voltage to be applied at the VPP pin during programming. This voltage must be supplied from the board. Under normal operating conditions, VPP and VPPNVM must be connected to their respective supply range.

  • Page 26: Auto Programming

    Auto Programming Auto Programming In auto programming mode, SmartFusion2 and IGLOO2 devices program themselves by downloading the bitstream from an external SPI flash device. The system controller configures the MSS or HPMS SPI_0 port for the SPI master mode when the dedicated FLASH_GOLDEN_N pin is asserted low upon system reboot.

  • Page 27: Figure 10 Smartfusion2/Igloo2 Mss/Hpms Spi_0 Port Configured For Auto Programming (Except 050 Device)

    The system controller reads the SPI flash device ID and device density to determine the read algorithm, and then programs the device with the bitstream. In auto programming, SmartFusion2 and IGLOO2 devices are blank, and hence SPI signal polarity is mode 3 (SPO=SPH=1).

    The design version of the update image must be greater than the image version already programmed in the device. When auto update is enabled, SmartFusion2/IGLOO2 MSS/HPMS SPI_0 can be configured to share the SPI_0 pin with an SPI controller implemented in the FPGA fabric. To share the SPI_0 port, a multiplexer needs to be implemented in the FPGA fabric to switch the SPI_0 pins between MSS/HPMS SPI_0 and the fabric SPI controller.
