基于S3C2440的U-Boot开机logo的设计与实现

摘要

在对U-Boot进行深入分析的基础上,同时对S3C2440的LCD控制器原理以及INNOLUX 7寸LCD的成像原理进行分析,最后结合系统软硬件特性实现基于U-Boot的开机logo。通过实验验证表明,在U-Boot上实现开机logo,可在无操作系统下为开发者以及用户提供友好开机信息。%Based on U-Boot depth analysis,studied the S3C2440 LCD controller and INNOLUX 7-inch LCD image-forming principle in detail.At last,achieved boot logo combineing with the system hardware and software features.Experiment results show that achieving the boot logo on U-Boot can provide developer and user with friendly boot information.
