Research on Firmware Upgrade Method of PCIE Board Based on FPGA

This design is based on the PCIE IP core and Master SPI configuration mode of PANGO Logos2 series FPGA. A method of remotely upgrading FPGA firmware through PCIE interface is designed, and the method is applied to PCIE board card based on PANGO Logos2 series FPGA. The PCIE DMA controller and SPI FLASH controller are designed, and the stability of remote upgrade of board firmware is improved by multi-bit stream startup, and the application of the product is improved. It can be applied to communication equipment, network interface card, storage system, password card and other fields.
