This paper describes powerful, reliable Bootloader in the development of Embedded Systems transplant on the S5PV210 microprocessor based on Cotex-A8. It narrates the boot process, analysis of transplantation and procedure of transplantation in detail and implements loading the kernel and ysffs2 root filesystem. Finally, it uses the way of written U-Boot boot parameters to automatic load the kernel via TFTP and mount the root file system via NFS. It ultimately starts embedded linux system and confirms the feasibility of the transplanted U-Boot booting Linux System on the S5PV210.
