Android平台Bootloader的刷屏功能扩展设计

Android系统在正常启动中，刷屏功能一般在内核中执行，而Bootloader的任务应该是执行硬件初始化，并尽快跳转到Linux内核。在Bootloader启动过程中使能一个显示驱动，实现刷屏功能，并不违背这一目标。本文通过对Boot—loader的原理分析和嵌入式芯片C6310中LCD控制器的研究，设计了Bootloader中LCD硬件初始化和软件驱动程序。该设计完善了Bootloader的扩展功能，加快了手机动画的实现，改善了客户的使用体验。

Bootloader Refresh Function Based on Android Platform

In normal start, the refresh function of Android system will be executed in the kernel, and the Bootloader task should perform hardware initialization, and as soon as possible jump to the Linux kernel. In Bootloader hoot process, enabling display driver to achieve refresh function is not contrary to this goal. In this paper, by the Bootloader principle analysis and the LCD controller study in the em-bedded chip C6310, the the Bootloader LCD hardware initialize and software drivers are designed. The design consummates Bootloader extensions, accelerates the realization of the mobile phone animation and improves customer experience.
