Abstract

The embodiment of the invention relates to a software starting method, wherein the software is stored in a first partition and a second partition of a storage device respectively, the software starting method comprises the steps that starting information is read, the starting information comprises a current starting partition, and the current starting partition is the first partition or the secondpartition; judging whether the current starting partition can normally start the software or not, and switching the current starting partition into the other one of the first partition and the secondpartition if the current starting partition cannot normally start the software; and starting the software from the current starting partition. The method can be particularly used for solving the problem that after OTA upgrading, when a system mirror image is damaged due to nonvolatile storage damage (such as an eMMC bad block, a hard disk bad track and the like), starting cannot be carried out. At present, the method can be applied to a vehicle-mounted computing unit (an automatic driving computing unit).

Description

technical field [0001] The present invention generally relates to the technical field of computer software, and in particular to a method for starting software and an OTA upgrade method and device for a vehicle-mounted operating system. Background technique [0002] With the continuous and rapid development of communication technology, terminals such as computers, mobile phones, and vehicle-mounted intelligent systems are becoming more and more popular. In addition to hardware, the terminal also requires various software to work normally, such as an operating system and various application software (such as navigation software). These software often need to be continuously upgraded in order to make the system more secure and perfect. For example, for a vehicle operating system, the operating system is version 4.0 when it leaves the factory, and it needs to be upgraded to version 5.0 and later. [0003] In the prior art, an upgrade operation of a terminal system is often im...
