Abstract

The invention discloses an embedded system starting method, device and equipment and a storage medium. The method comprises the following steps: when the embedded system is started, judging whether aspecified memory is in a writable protection state or not, if so, setting write protection for a specified region in the specified memory, otherwise, setting non-write protection for the specified region in the specified memory; wherein the specified memory is a memory in which a firmware mirror image of the embedded system is stored, and the specified area is an area in which a boot loader contained in the firmware mirror image is stored; and carrying out credibility detection on the firmware mirror image of the embedded system by utilizing the boot loader, if the detection is passed, continuously starting the embedded system, otherwise, determining that the embedded system cannot be continuously started. Problems existing in the prior art are avoided, and then wide application can be achieved.

Description

technical field

[0001] The present invention relates to the technical field of embedded systems, and more specifically, to an embedded system startup method, device, equipment and storage medium. Background technique

[0002] In the context of increasing global information security concerns, trusted startup of key equipment or components has gradually become a standard configuration. At present, trusted boot usually needs to be equipped with professional trusted components, such as TPM, TPCM, etc. On the one hand, these trusted components and their software are expensive; Complicated hardware design, these problems limit the wide application of trusted components. Contents of the invention

[0003] The purpose of the present invention is to provide a method, device, equipment and storage medium for starting an embedded system, which can avoid problems in the prior art when using trusted components to detect the credibility of an embedded system, and can be widely used . ...
