| Abstract: | TOPPERS/ASP is an open source implementation for micro ITRON 4.0.The method to port this kernel on ARM architecture is described.During the process of porting on S3C2440 microprocessor,the startup process of this kernel is analyzed.The hardware initialization program,the drivers for UART and timer and the priority-based interrupt handler program are also implemented.After finishing the porting process,this kernel is downloaded to the target board and can be controlled through the serial port,and accuracy of... |
