Abstract

The main task of bootloader is to copy the kernel image to RAM , and then jump to the entrance of the kernel to run the operating system . It is the first-running code when the system is powered on . U-boot , with its open-source codes , supporting for varieties of embedded operating system kernel , high reliability and stability , has been in the mainstream of bootloader . However , it has not yet provided the original support for the S3C2440 processor , neither does its NAND flash . This paper analyzes two flashes in reference to the corresponding start-up mode , and introduces the U-boot start-up procedures briefly and figures out the major steps of transplanting U-boot to the target platform . U-boot was transplanted successfully .
