Embodiment Construction

[0035] In order to make the purpose, technical solution and advantages of the present invention more clear, the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined arbitrarily with each other.

[0036] figure 1 , is an internal module diagram of a device for starting a system under a dual BOOT program environment according to an embodiment of the present invention.

[0037] The device comprises a first start control module 1 and a second start control module 2, wherein,

[0038] The first start control module 1 is used to start the first BOOT program. After the first BOOT program detects that the second BOOT program is complete and valid, it sends a start signal to the second start control module 2, or detects the second BOOT program through the first BOOT program. ...

Abstract

The invention provides a method and a device for turning on a system in a double-BOOT program condition. The method comprises the following steps of: turning on a first BOOT program; after detecting that a second BOOT program is entire and effective through the first BOOT program, turning on the second BOOT program and guiding the system to turn on; and after detecting that the second BOOT program is entire and effective through the first BOOT program, executing the first BOOT program, and guiding the system to turn on. With the adoption of the technical scheme provided by the invention, the stable operation of equipment turned on through the BOOT programs can be ensured.

Description

technical field [0001] The invention relates to the field of electronic communication, in particular to a method and device for starting a system in a double BOOT program environment. Background technique [0002] With the continuous growth of various communication services, the stable operation of the main control device of the terminal becomes particularly important, and the stable operation of the main control device first requires a stable and efficient BOOT startup program. The single BOOT startup program existing in the existing FLASH cannot provide sufficient guarantee for emergencies in the communication field, such as power failure. In addition, because the BOOT program needs to be continuously upgraded, if the existing single BOOT program encounters the above-mentioned emergencies during the upgrade, the BOOT program will be lost, thereby affecting the normal operation of the main control device. Contents of the invention [0003] The invention provides a method...
