The invention relates to the technical field of electronic circuits, and provides an FPGA firmware upgrade verification method and device, and the method comprises the steps: carrying out the analysis of a received transmission frame, and obtaining a frame analysis result; if the program data packet is the target data packet of the current FPGA chip, verifying the packet header and the effective upgrade program file to obtain a first verification result; upgrading the current FPGA chip based on the effective upgrading program file in the program data packet; reading back an effective upgrading program file of the upgraded current FPGA chip; verifying the read-back effective upgrading program file according to the output bit length of the read-back effective upgrading program file to obtain a second verification result; and under the condition of determining that the effective upgrade program file has the upgrade error, determining an upgrade error type based on the function judgment bytes.
