Embodiment 1

[0075] Such as Figure 4 , Figure 5 As shown, a system for remote FPGA firmware code update includes FPGA firmware with a check field (hereinafter referred to as FPGA firmware), a remote communication module, an MCU control module, an FPGA module and a FLASH memory.

[0076] FPGA firmware, including a check field, is used to provide firmware validity check.

[0077] The remote communication module is used to receive the commands and firmware files sent by the remote terminal, send the firmware files to the MCU control module, receive and send the commands sent back by the MCU, and record each update log information.

[0078] The MCU control module is used to parse the verification field in the received FPGA firmware, verify the validity of the firmware, and control the power-on and reset of the FPGA module.

[0079] The FPGA module is used to receive the firmware that has been verified by the MCU and solidify it into the FLASH memory.

[0080] FLASH memory, used to store F...

Abstract

The invention provides a remote FPGA firmware code update system, method and a medium, comprising: a remote communication module, an MCU control module, an FPGA module and a FLASH memory; the remote communication module is connected with an MCU control module, the MCU control module is connected with an FPGA module, and the FPGA module is connected with a FLASH memory. FPGA firmware is stored in that FLASH memory. The invention uses the MCU control module to verify the validity of the firmware and prevent the system from being illegally updated with the firmware. The verification field is stored in MCU beforehand to prevent the leakage of verification information and ensure the safety of the whole system. Using MCU control module, FPGA reset can be controlled, so that the firmware can takeeffect without power-off and restart after updating; the MCU control module is used, the power-on sequence of FPGA can be controlled, and whether the power-on firmware is successful or not can be detected to ensure the reliability of the system.

Description

technical field [0001] The invention relates to the technical field of programmable logic devices, in particular to a remote FPGA firmware code update system, method and medium. In particular, it relates to a method for remotely safely updating firmware codes of an MCU-based FPGA. Background technique [0002] At present, with the rapid development of semiconductor technology, Field Programmable Gate Array (FPGA) has been widely used in many product designs, and even used to replace dedicated IC chips in many occasions. FPGA has abundant logic resources and IO resources, and has the advantages of short design cycle, low development cost, low risk and high reliability. With the wide application of FPGA, the method of remotely updating FPGA firmware code is also used on a large scale. [0003] For the common method of remotely updating the FPGA firmware code, many patent documents have proposed solutions, but basically the configuration needs to be powered off and restarted ...
