| description | According to the firmware updating system and method, a maintenance terminal divides new firmware into a plurality of data packets, and after MD5 encryption is conducted on each data packet, the encrypted data packets are transmitted to a BMC module in a partitioned mode; the BMC module carries out MD5 decryption on a plurality of data packets of the received new firmware and then sends the data packets to the FPGA module; the FPGA module runs old firmware in the first storage area, and the FPGA module temporarily stores a plurality of data packets of the received new firmware in the second storage area; and the FPGA module verifies the plurality of data packets of the new firmware, and after the verification is passed, the FPGA module erases the old firmware in the first storage area, and writes the new firmware passing the verification in the second storage area into the first storage area. The upgrading process does not affect normal use of firmware, non-inductive upgrading is achieved, the safety coeffici |
