Embodiment Construction
[0056] In order to facilitate the understanding of the present invention, the present invention will be described in more detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that when an element is said to be "fixed" to another element, it may be directly on the other element, or there may be one or more intervening elements therebetween. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or one or more intervening elements may be present therebetween. The orientation or positional relationship indicated by the terms "upper", "lower", "inner", "outer", and "bottom" used in this specification is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the The invention and the simplified description do not indicate or imply that the device or element referred to must have a specific orientation...

The invention discloses a micro-control unit software upgrading method, electronic equipment and a storage medium. The method comprises the following steps that: a micro-control unit memory is divided into a plurality of partitions; the bootstrap program of the micro-control unit comprises a first bootstrap program and a second bootstrap program, and the first bootstrap program and the second bootstrap program are stored in different partitions of a memory of the micro-control unit; a micro-control unit upgrading file transmitted through the system-on-chip is stored in a specified partition of a micro-control unit memory; and according to the upgrade request information, the first guide program or the second guide program guides the upgrade of the micro-control unit upgrade file, or when the upgrade of the micro-control unit upgrade file fails, the first guide program or the second guide program guides the program version which fails to upgrade to back. Through the embodiment of the invention, both the bootstrap program and the application program can be upgraded or the version of the program can be retreated, so that the convenience and the reliability of using the software program are improved, the maintenance cost is reduced, and the user experience is improved.
Description
technical field [0001] The invention relates to the technical field of electronic circuits, in particular to a micro control unit software upgrading method, electronic equipment and a storage medium. Background technique [0002] With the development of autonomous driving and Internet of Vehicles technology, the iteration of Advanced Driving Assistance System (ADAS, Advanced Driving Assistance System) software update is accelerating, which puts forward higher requirements for ADAS software upgrade. ADAS hardware is generally made up of Microcontroller Unit (MCU, Microcontroller Unit), SOC (System-on-a-Chip, System-on-a-Chip), wherein the program of MCU generally includes bootloader and application program; wherein, the bootloader is used to complete Application program loading, application program upgrading, device configuration information reading, and complex diagnostic function tasks; the application program is used to complete corresponding functional tasks. After the f...
