U-Boot transplantation analyses for embedded system

U-Boot software was introduced firstly.It is a powerful developing instrument of Bootloader in embedded system.And Bootloader is used for loading the embedded system when the system is started up and it is the foundation for developing embedded system.Then,taking the UP_NETARM3000 developing board as basis,detail procedures for transplanting U-Boot to Samsung S3C44B0 microprocessor were analyzed with combining the practical transplant process.The experimental results indicate that the transplanted U-Boot can run on the target board successfully.It can communicate with host by serial port,watch the memory on target board,and write the kernel of operation system and file system.
