Embodiment Construction

[0017] In order to describe the technical solution of the present invention more clearly and completely, the present invention will be further described below in conjunction with the accompanying drawings.

[0018] Please refer to figure 1 , the present invention proposes a protection design method for bootstrap, comprising:

[0019] A bootloader is stored in the Bootloader partition of the logical partition of the storage device, and the same bootloader as the bootloader in the Bootloader partition is also stored in the inherent partitions Boot0 and Boot1 of the storage device, and the backup startup of the bootloader in the partition is set The order is: Bootloader first, Boot0 second, and Boot1 last;

[0020] When starting the data of the Bootloader partition, first check its integrity. If it is complete, the boot program will be loaded from the Bootloader partition; if it is incomplete, quickly start the Boot0 partition data in the backup plan;

[0021] When starting the...

Abstract

The invention provides a protection design method of a bootstrap program. The method comprises the following steps of: storing a boot program in a Bootloader partition of a logic partition of a storage device, storing boot programs which are the same as the boot programs in the Bootloader partition in an inherent partition Boot0 and an inherent partition Boot1 of the storage device; and setting abackup starting sequence of the boot programs in partitions: firstly, the Bootloader, then the Boot0, and finally, the Boot1. The problem that the boot program is empty or the boot program in the Bootloader partition is damaged to cause that the system cannot be started due to a power failure phenomenon in the upgrading process of the intelligent terminal equipment can be effectively prevented.

Description

technical field [0001] The invention relates to the field of embedded system application, in particular to a boot program protection design method. Background technique [0002] At present, the software system of smart terminal equipment often needs to be upgraded with the use cycle. On the one hand, upgrading the software can effectively solve various problems in the software of the smart terminal equipment after the manufacturer leaves the factory, including the part of the boot program. bug, it is necessary to use Ethernet to upgrade the end user's machine; on the other hand, in order to improve the market competitiveness of their products, manufacturers will launch new software products every once in a while, and some functions may need to modify the boot program. The corresponding upgrades are also required from time to time. [0003] In the upgrade process of smart terminal equipment, in order to ensure the integrity of the upgrade, the industry usually adopts such a ...
