Problems solved by technology
However, the existing technology generally only uses one upgrade method to upgrade the program in the MCU, and it is impossible to switch the upgrade method flexibly according to the upgrade data and the size of the memory space of the electronic device, which makes the reliability of the program upgrade lower.

Embodiment Construction
[0054] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings but not all structures.
[0055] At present, there are generally two options for receiving the upgrade data of the program to be upgraded: the first is to receive the upgrade data through the backup area, after the upgrade data is received, if the upgrade data is complete, copy the upgrade data in the backup area to the program to be upgraded area to realize program upgrade; the second is to erase the program area to be upgraded first, and then directly store the upgrade data into the program area to be upgraded. The advantage of the first...

The embodiment of the invention discloses an upgrading method and an upgrading device for electronic equipment. A micro-control unit is configured in the electronic equipment, the upgrading method of the electronic equipment is suitable for upgrading a to-be-upgraded program in the micro-control unit, and a memory area of the micro-control unit comprises a first storage area, a second storage area and a to-be-upgraded storage area; the electronic equipment upgrading method comprises the following steps: judging whether a first storage area has a space for storing upgrading data or not; when the first storage area has the space for storing the upgrading data, receiving an upgrading instruction through the to-be-upgraded storage area or the second storage area so as to store the upgrading data in the upgrading instruction into the first storage area; when the first storage area does not have the space for storing the upgrading data, the upgrading instruction is received through the second storage area to store the upgrading data in the upgrading instruction into the to-be-upgraded storage area, so that the to-be-upgraded program is upgraded, and the upgrading mode is adaptively adjusted according to the memory space required by the upgrading data.
Description
technical field [0001] The embodiments of the present invention relate to the technical field of program upgrading, and in particular, to an upgrading method and device for electronic equipment. Background technique [0002] Electronic equipment, such as converters, electronic switches, and electronic AC power controllers, and other equipment with power electronic devices as the main functional components, after the production and assembly are completed, it is generally difficult to program the software to the micro control unit ( Micro Controller Unit, MCU). Therefore, in the prior art, the program software inside the MCU is mostly upgraded by means of online software upgrade, that is, the upgrade data is transmitted to the MCU in the electronic device by means of communication, without relying on the programming interface for programming. However, in the prior art, only one upgrade method is generally used to upgrade the program in the MCU, and the upgrade method cannot b...
