【摘要】 Blob(Boot Loader Object)是一款功能强大的Bootloader,多用于S3C44B0而少用于S3C2440A。介绍了常见的Bootloader;归纳了Blob的主要特征;分析了其运行过程,介绍了系统存储空间分布;给出了Blob在基于S3C2440A开发板上的移植方法、移植过程,最后给出了测试结果。目前,Blob能够稳定地运行,为下一步开发工作奠定了良好的基础。更多还原

【Abstract】 Bootloader Blob has enough functions and is widely applied in S3C440 BO but less in S3C2440A.In this paper,many Bootloaders are intrudeced,the main characters of Blob are sumed up,the process of Blob in-depth is analyzed,the system memory distribution in the Embedded system board based on S3C2440A is explained,particularly the porting method,porting process and test in the board.Finally the test results are given.Currently,Blob runs steadily,establishing good foundation for farther development work.更多还原
