| Abstract: | Bootloader programme is an important part of ARM embedded system.Low cost and huge capacity is the advantage of NandFlash storage,which has been applied in embedded systems widely.Based on the features of S3C2440 micro-processor and NandFlash storage,the method for operating the NandFlash and fault process has been discussed as well as the execution flow of bootloader.The method and approach for system booting from NandFlash has been given.The bootloader based on NandFlash storage booting,which is designed modularly and could be ported to other different develop platforms very easily,has been prepared for further development of embedded system. |
