| Abstract: | Analyzing the process of the U-Boot boot in the S3C2440A processor, according to the feature that S3C2440A processor supports the boot of Bootloader from NOR Flash and NAND Flash and the difference that U-Boot boots form NOR Flash and NAND Flash, a method of implementing U-Boot which supports Dual-Boot of NOR Flash and NAND Flash is proposed. The eventually realized source code is correctly compiled in the ARM-Linux cross-compiler and runs stably in development board based on S3C2440A processor. |
