Problems solved by technology

[0003] In the existing uboot startup method, the uboot is burned into a non-type flash memory or SD card controller for startup. If the uboot cannot be started, the system-on-chip cannot work normally. At this time, it is necessary to burn the flash memory on-site to restart the uboot
[0004] However, if the flash memory is burned on-site, it will increase the difficulty of on-site maintenance, and in the process of burning, it is easy to tamper with uboot, which increases security risks

Embodiment Construction

[0052] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0053] see figure 1 , figure 1 This is a first flowchart of a uboot startup method provided by the embodiment of the present application.

[0054] A uboot startup method provided by an embodiment of the present application may include the following steps:

[0055] Step S101: Determine the uboot to be started of the target SoC.

[0056] In practical applications, the uboot to be started in the target system-on-chip may be determined f...

Abstract

The application discloses a uboot starting method, system, device and computer storage medium, which determines the uboot to be started of the target system on chip; judges whether the uboot to be started is safe; if the uboot to be started is safe, then starts the uboot to be started; if the uboot to be started is If the uboot is not safe, the target uboot is obtained remotely through the network, the uboot to be started is deleted, the target uboot is stored in the target system-on-chip, and the step of determining the uboot to be started in the target system-on-chip is returned. This application avoids on-site burning uboot and malicious modification of uboot. In addition, the target uboot will be written into the target system-on-chip, and returns to the step of judging whether the uboot to be started is safe, that is, only the uboot to be started in the target system-on-chip When it is safe, the uboot to be started will be started to ensure the safe start of uboot.

Description

technical field [0001] The present application relates to the technical field of uboot startup, and more particularly, to a uboot startup method, system, device, and computer storage medium. Background technique [0002] As a system on a chip (SoC) is widely used in various fields such as servers, the uboot (Universal Boot Loader, boot loader) startup process of the system on a chip is also more and more concerned by users. [0003] In the existing uboot startup method, uboot is burned in non-type flash memory or sd card controller for startup. If uboot cannot be started, the on-chip system will not work normally. At this time, it is necessary to burn the flash memory on site to restart uboot. [0004] However, if the flash memory is burned on site, it will increase the difficulty of on-site maintenance, and during the burning process, it is easy to tamper with the uboot, which will increase security risks. [0005] To sum up, how to improve the startup security of uboot is...
