Problems solved by technology

However, this solution still has the following deficiencies: other actions are prohibited during the startup of the vehicle operating system, and other operations are not allowed until the operating system is stable, such as reversing after the operating system is stable, and reversing cannot be performed at the same time when the operating system is started

Embodiment

[0030] Embodiments of the present invention provide a method for quickly starting a vehicle-mounted android operating system when backing up, such as figure 1 shown, including the following steps:

[0031] S01, initialize the framebuffer in uboot;

[0032] In Linux version 2.2X and above, framebuffer is a driver interface, which can be understood as "frame buffer", which refers to the mapping of the content displayed by the graphics device in the video memory, and is an abstraction of the graphics hardware device. Use The framebuffer is connected with the graphics hardware and is the interface for the user to enter the graphics interface.

[0033] The core code of this step is as follows:

[0034]

[0035]

[0036] While initializing the framebuffer in uboot, it also includes:

[0037] Initialize the LCD display driver 1 second after the system is powered on, and display the customer logo picture on the system startup interface layer (LCD-Lay3).

[0038] S02. Detect ...

Abstract

The invention discloses a method supporting fast vehicle-mounted android operating system start during backing-up, which is characterized by comprising the following steps: initializing framebuffer in a uboot; detecting whether a backing-up signal exists in the uboot process, if yes, displaying a backing-up interface, if no, displaying a logo start interface; detecting whether a backing-up signal exists in a kernel drive when a system enters kernel uploading process, if yes, displaying a backing-up interface, if no, displaying a system starting interface; starting OS layer interface display, and ending android system start; after the start of the system, detecting whether a backing-up signal exists in a kernel layer, periodically querying the backing-up state in the kernel layer in an application layer, if the system is in a backing-up state, starting a camera application and displaying the backing-up interface, and if backing-up completion is detected, exiting from the camera application. According to the invention, three starting processes of starting the vehicle-mounted android operating system are connected in a seamless manner. The method supports that the vehicle-mounted android operating system starts backing-up during system starting-up, that is, a screen displays backing-up conditions, and at the same time starting-up runs properly.

Description

technical field [0001] The invention relates to automotive electronic technology and embedded development technology, in particular to a method for quickly starting a vehicle-mounted android operating system when reversing. Background technique [0002] With the popularity of cars, people have higher and higher requirements for the intelligence and interactivity of cars. For example, when reversing, I used to rely on the rearview mirror, but now I basically only need to watch the LCD of the center console. [0003] At present, the operating system in the automotive industry mainly uses the winCE operating platform. The winCE system starts quickly, and the booting process only takes 7-10 seconds. As long as there is a reversing during the system starting process, the machine will be restarted and enter the reversing program. Wait until the reversing is over. Then restart, that is, after the end of reversing, it only takes 7-10 seconds to start to enter the system. [0004] ...
