Uboot-based starting interface implementation method and system, terminal and readable storage medium

Abstract

The invention provides a uboot-based starting interface implementation method and system, a terminal and a readable storage medium, and the method comprises the steps: configuring an LCD starting interface operation port based on a uboot module; configuring a picture editing module, and setting a picture display parameter editing module; establishing a character library and a character library; configuring a character modulo tool and a character editing module; acquiring graphic information, pixel information of the graphic information and color information according to a preset mode; obtaining character information and character information through a character modulo tool and a character editing module; and adding the character information and the character information to the image information to form a uboot file, and storing the uboot file in a starting storage area. Reading before system starting can be achieved, a user starting interface is displayed through an LCD during starting, and a fixed logo capable of being designed through image display is added. And a small-capacity word stock is established according to the interface content, so that the limitation of the size of the uboot firmware is overcome, and meanwhile, a complex user interface can be designed.

Description

Technical field [0001] The invention relates to the field of computers, in particular to a method, a system, a terminal and a readable storage medium for realizing a boot interface based on uboot. Background technique [0002] The full name of uboot is Universal Boot Loader, that is, Universal Bootloader. It is a kind of Bootloader commonly used in embedded systems. It is a small program that runs before the operating system. Through it, we can initialize hardware devices and establish memory space mapping. Table to establish an appropriate hardware and software environment to prepare for the final call to the operating system kernel. Therefore, the user can see the operation interface after operating the system, and the uboot obtained now cannot display the startup interface graphics through the LCD before the system starts, which brings inconvenience to the user. [0003] uboot has limitations on the size of its firmware. The user-friendly interface requires complex image and ch...

AI Technical Summary

Problems solved by technology

Therefore, after operating the system is the user-visible operation interface, and the uboot obtained now cannot display the startup interface graphics through the LCD before the system starts, which brings inconvenience to the user

[0003] Uboot has a limitation on the size of its firmware, and the friendly user interface requires complex image and character display, and the basic methods such as image two-dimensional array conversion and storage are far from meeting the needs

The existing Chinese character library also takes up a lot of memory. The existing commonly used font library is about 22,000 Chinese characters close to 280kb, which cannot meet the size limit of the firmware.
