The embodiment of the invention provides a firmware program updating method and device, a storage medium and electronic equipment, and the method comprises the steps that a firmware program obtains afunction address of a drive program corresponding to a firmware extension function in a drive entry table, and the function address of the drive program is registered in the drive entry table in advance; and the firmware program calls the firmware extension function according to the function address so as to update the function of the firmware program. According to the embodiment of the invention,the to-be-updated function is written into the single-chip microcomputer by adopting the drive program, so that the function of the firmware program can be increased or modified by adding the drive program, the program can be updated without downloading the complete firmware program, the drive program can be downloaded remotely, and therefore, function updating can be realized without a fixed interface, and the overall performance of the single-chip microcomputer is improved.
Description
technical field [0001] The disclosure relates to the field of single-chip microcomputers, and in particular to a firmware program updating method, device, storage medium and electronic equipment. Background technique [0002] At present, single-chip microcomputers are widely used in small and micro devices in various fields. The resources of single-chip microcomputers are usually very limited, and it is difficult to run Windows, Linux or even Android systems. Usually, the firmware program is directly written in a non-systematic way. As a result, when the single-chip firmware program expands its functions, it is often necessary to re-download the firmware program through the programming interface, which is very inconvenient. [0003] The existing solution is usually to download a startup program in the single-chip microcomputer. The startup program will jump to the firmware program to execute in the normal working mode. After the download mode is triggered, the startup progr...
