Embodiment Construction

[0026] The capsule customization update method based on the universal extensible firmware interface firmware system proposed by the present invention will be described in detail below in conjunction with the accompanying drawings:

[0027] The present invention is based on a capsule-type custom update method of a universal scalable firmware interface firmware system, figure 1 For the update flow chart of the method, the FV module to be updated is compiled through the EDK II compilation specification, and the FV is packaged into a Capsule. During the startup process of UEFI firmware system, the Capsule is parsed, and the starting address and size of FV in Flash are obtained, so as to meet the design requirements for updating the selected FV. Specific steps are as follows:

[0028] Step (1): Compile the FV module that needs to be updated according to the EDK II compilation specification, and encapsulate the FV into a Capsule.

[0029] Step (2): The update program under the ope...

Abstract

The invention provides a capsule type custom-made updating method based on a universal and extensible firmware interface firmware system. The method is based on a capsule mechanism of a unified extensible firmware interface (UEFI) firmware system and gets rid of that the current mainstream firmware updating technology depends on system management interrupt (SMI) drive. Through analysis of a capsule, a firmware volume (FV) module to be updated is obtained, the FV module is identified, and obtained data are wrote in firmware file system target addresses, therefore updating of the selected FV module is achieved, and a method which needs to update a whole basic input / output system (BIOS) is got rid of. The capsule mechanism solves the problem that updating tools on different hardware platforms and operation systems cannot be unified. The firmware updating method is flexile, high in application value and capable of being applied to the aspects of firmware remote refreshing, automatic firmware recovery and the like.

Description

technical field [0001] The invention belongs to the technical field of software updating of computer software engineering technology, and specifically refers to a capsule-style custom updating method based on a universal scalable firmware interface firmware system. Background technique [0002] With the deepening of Internet-based related services such as cloud computing, customization of client firmware in the fields of securities, finance, and telecommunications has become a new application hotspot. Embedded products such as networking appliances and kiosks require devices that have unique capabilities rather than function like general-purpose computers. So system developers are increasingly seeking to differentiate their products and gain a competitive advantage by adding more features, and the firmware system is an ideal place to enhance this feature. Such as user interface, quick guide, and adding special functions. However, the particularity of these industries leads...
