Abstract: The embedded system is limited by system resources for its hardware and operating environment. It proposes the design of U-Boot with low system resources. By initializing the experimental platform and setting the software environment, it used the kernel of Linux on version 2.6.30.4. The U-Boot size is only 2.32 kB. Thus, the U-Boot, which uses fewer system resources on the embedded system, leaves more resources for other modules and makes the embedded system more powerful.
