| Abstract: | Bootloader U-Boot has enough functions and comprehensive applications,but when porting it to the ARM microprocessor S3C2440A is a relatively complex work.We briefly introduced many general Bootloaders,gathered up the main characters of U-Boot,analyzed the process of U-Boot in-depth,clearly explained the system memory distribution and the hardware resource configuration in our Embedded System board based on the CPU SAMSUNG S3C2440A,particularly introduced the porting method,porting process and main porting feature of U-Boot in the board.In the end,we get the results in the test experiments.Currently,U-Boot could achieve to the designed functions and runs steadily,establishing required foundation for farther porting Linux OS. |
