This mode requires devices to have required firmware for Cortex-M3 to implement these features. Cortex-M3 core receives the bitstream and feeds to the system controller which in-turn programs the device.

In-System Programming (ISP) – This mode is supported in SmartFusion2 SoC FPGA devices and allows devices to fetch programming bitstream from communication ports like USB, UART, SPI, I2C etc. This mode is also useful in field upgrades. The system controller configures SPI master mode and other on-chip resources to enable the programming.Īuto Update – Auto-update mode allows a pre-programmed device to be automatically programmed with an updated bitstream image if image is available in external SPI flash whenever devices powers-up or comes out of hardware reset. For SPI programming, a dedicated port SPI_SC is available.Īuto Programming – In this mode, the devices are automatically programmed by downloading the bitstream from an external SPI flash memory. The system controller residing inside the device handles the programming and complies to IEEE 1532 and IEEE 1149.1 JTAG standards. Device can be programmed either using JTAG interface or SPI. PolarFire, SmartFusion2 and IGLOO2 devices support programming via an external master as well as self-programming. The solution comprises hardware, software, and collaterals, which allow easy access to the programming and debugging features available in SoC FPGA and FPGA devices and shorten the learning curve.
