Problems solved by technology

The connection of the JTAG interface is complicated. If it is used as an external interface of the device, the utilization rate of this interface is not high, and it will affect the appearance of the device; if it is not used as an external interface of the device, the update program will inevitably require tedious device disassembly.
[0003] Using the JTAG emulator to solidify the Flash program requires carrying a de

Abstract

The invention discloses a program updating method and system based on an FPGA. The updating method comprises the following steps that firstly, a soff file and an elf file are synthesized into a hex file through a script sh file; and then an upper computer reads the hex file, sends the hex file to the FPGA through a serial cable, and controls the FPGA to write data in the hex file into the Flash according to address information, thereby realizing program updating and solidification. The programming solidification of the FPGA program is realized by combining the external serial port with the upper computer program, complex equipment disassembly and installation work is not needed, the programming solidification time of the program is about 10 minutes, the efficiency is greatly improved, andthe efficient utilization of external serial port resources is realized.

Description

technical field [0001] The invention belongs to the technical field of electronic communication, and in particular relates to an FPGA-based program updating method and system. Background technique [0002] SRAM-based technology FPGA, due to the special process characteristics of SRAM, FPGA data will be lost after power off. Therefore, power-down non-volatile memory is often used, combined with FPGA to build an embedded system. EPCS (Erasable Programmable Configurable Serial) Flash belongs to the serial interface, which has the characteristics of simple interface, small size and convenient configuration. It is often used to store FPGA configuration files and Nios II executable codes. After reasonable configuration, FPGA can directly read files from EPCS Flash and start the system. At present, the commonly used FPGA program curing method is: first, merge and convert the FPGA configuration file (.sof file) and Nios II executable code (.elf file) into a jic file, and then use ...
