2440没有从SD卡启动的功能，但通过在SD卡里建立文件系统，可以实现2440从SD卡启动，附件是我对2440SD卡启动的理解。-2440 does not boot from the SD card functionality, but through the establishment of the SD card file system, can boot from the SD card 2440, annex I to the 2440SD card start understandi

基于s3c2410、2440的从SD卡引导Linux内核程序，实现FAT文件系统，读取SD卡内的Linux内核到SDRAM中，并运行。-Based on s3c2410, 2440 from the SD card boot Linux kernel procedures, implementation FAT file system, read the SD card inside the Linux kernel to SDRAM, and running.

2440平台，SD卡启动WINCE，全部源码,做嵌入式的应该懂:-)-2440 platform, SD card boot WINCE, all the source code, so embedded should know :-)
