| Abstract: | S3C44B0X Microprocessor which base on ARM7TDMI is extensively used,Blob becomes greatly fit uClinux on S3C44B0X because it has strong function,expedient use and easy Porting.This article stress the process of the inside registers and the function block of the ARM processor,after the embedded sys- tem has powered on before the run of operation system or application program,then by using the start up code of the S3C44B0X,thoroughly explain the blob,the startup process of the embedded system. |
