Program upgrading method and device, electronic equipment and storage medium

The invention provides a program upgrading method and device, electronic equipment and a storage medium, and relates to the technical field of network communication design. The method comprises the steps: writing an obtained upgrading program into a plug-in storage chip of a target chip, wherein the storage chip comprises a first area and a second area, the first area is used for storing a source program corresponding to the upgrading program, and the second area is used for storing the upgrading program; and controlling the target chip to load the source program or the upgrading program in the storage chip to obtain an upgraded target program. According to the method and the device, program upgrading is carried out on the target chip through the external storage chip of the FPGA target chip, the power consumption and difficulty during upgrading are reduced, the upgrading program is written into the storage chip, and two program schemes are stored in the storage chip, so that the target chip can load the two
