Abstract

The invention discloses an online upgrading method and system for FPGA firmware. The method comprises the steps of enabling an FPGA to obtain a write configuration number through communication with aDSP; carrying out an erasing operation on the EPCS configuration chip; performing write operation on the configuration chip to obtain a firmware upgrading version number, and sending a configuration completion signal to the DSP; obtaining an nCONFIG low level signal according to the nCONFIG low level signal; the FPGA enters a configuration and initialization state; judging whether the INIT _ DONEsignal is a high-level signal or not; if yes, communication between the FPGA firmware and the DSP is reestablished, and the firmware upgrading version number is sent to the DSP; dSP judging whether upgrading succeeds or not. According to the invention, online upgrading and automatic restarting of FPGA firmware can be realized; and an online configuration monitoring function is achieved, the DSP can determine whether the FPGA is successfully upgraded or not in real time, and the reliability of online upgrading is improved.

Description

technical field [0001] The invention relates to the field of electronic information technology, in particular to a method and system for online upgrading of FPGA firmware. Background technique [0002] In power electronic systems, the control scheme of DSP+FPGA is usually used to upgrade the FPGA firmware. This solution combines the characteristics of FPGA with rich programmable resources, parallel pipeline processing and relatively strong computing power of DSP, which can reduce hardware costs and improve product performance. [0003] At present, the methods for upgrading the FPGA firmware include: (1) online programming through the Nios II soft core, which has high hardware cost and low efficiency. (2) The Nios II soft core is not used, and the DSP is connected to the FPGA through a parallel interface to realize the online upgrade of the FPGA. The TMDC completes the conversion of the rpd format burning file according to the communication handshake protocol, and communicat...
