在上一节中我们已经完成了把u-boot.bin从SD卡上拷贝到DDR内存，并跳转到DDR内存中去执行u-boot的工作。这节仅先记录下如何把SDCard用起来，并且把Kernelboot起来的一些具体的操作，详细分析后面再写。
1、Tiny4412 SDCard用起来
代码修改如下：

2、Kernel boot起来
2.1 先把u-boot烧进SD卡，并把uImage、ramdisk.img和exynos4412-tiny4412.dtb拷贝进SD卡,这三个文件的下载地址为：http://files.cnblogs.com/files/AP0904225/tiny4412-test-image.tar.gz
tiny4412开发板从SD卡启动后，使其进入u-boot命令行状态，如下图所示：
2.2 输入mmcinfo命令查看下SD/MMC设备信息：
2.3 设置bootcmd参数
设置bootcmd变量为 "load mmc 0 0x40007000 uImage; load mmc 0 0x48000000 ramdisk.img; load mmc 0 0x42000000 exynos4412-tiny4412.dtb; bootm 0x40007000 0x48000000 0x42000000"；并保存。
load mmc 0 0x40007000 uImage 是把SD卡上的uImage文件读到内存地址为0x40007000处；
load mmc 0 0x48000000 ramdisk.img 是把SD卡上的ramdisk.img文件读到内存地址为0x48000000处；
load mmc 0 0x42000000 exynos4412-tiny4412.dtb是把SD卡上的exynos4412-tiny4412.dtb读到内存地址为0x42000000处；
bootm 0x40007000 0x48000000 0x42000000是告诉u-boot从0x40007000处启动内核，并告诉内核ramdisk.img和设备树文件（*.dtb）的地址为0x48000000、0x42000000
2.4查看下u-boot的环境变量：
然输入boot命令后就把kernel boot起来了
