摘要
板级支持包BSP(Board Support Pakage)是为目标系统提供的支持软件,是嵌入式系统设计的重点之一。在介绍BSP的概念和功能的基础上,针对μClinux和ARM7嵌入式系统教学实验平台,详细讨论了u-boot的移植过程和关键环节。系统启动实验表明移植后的u-boot实现了BSP的功能,说明移植、扩充u-boot是BSP开发的一种有效方法。
As one of most important parts in embedded system design,the Board Support Package （BSP） is a support software provided for Target System. On the basis of introducing the concepts and functions of BSP,we will focus on the μClinux and ARM7 embedded teaching experimental platform,and discuss the transplant process and the key link of the u-boot in detail. The system start-up experiment suggests that the transplanted u-boot has achieved the functions of the BSP,and this further indicates that the transplantation and expansion of u-boot is an effeetive method for developing BSP.
