TI中文支持网ti的技术支持和论坛上的大牛们，现在我这边通过SD卡烧写镜像到emmc中，一直烧写不成功，我的做法是通过SD卡进入到系统下面后，手动执行脚本的做法，不是设置的开机自启动来烧写的，手动执行脚本的打印信息如下：各位帮忙看看！有提示sfdisk的问题！不知道各位烧写成功的打印信息是啥样的！

另外还有一个想法是通过SD卡进入到系统下面后，手动来对emmc进行分区，使用的工具是fdisk，把emmc分为2个分区，一个是mmcblk1p1和mmcblk1p2，然后分别格式化为vfat和ext3，然后在/mnt目录下分别建立两个文件夹，分别挂载这两个分区，然后mmcblk1p1通过tftp把MLO,u-boot.img,am335x-boneblack.dtb,uImage这几个文件下载到挂载的文件夹中，mmcblk1p2通过tftp把rootfs下载到挂载的文件夹中，这样算不算烧写好了？

不知道您有没有看过这篇文档，这里有对SD卡烧写eMMC方法的描述：

回复 Jian Zhou:
已经下载了这个pdf，这里面关于SD卡烧写的，我就是按照上面的来操作的，打印信息就是上面的！
Lu Simon：
回复 Jian Zhou:
請問您那篇文檔有提到 将 SD 卡上文件系统中的/etc/init.d/fetcher.sh 修改,但是我沒有這個檔案(fetcher.sh)??請問該怎麼處理與修改?謝謝您!
PS : 我用的SDK : ti-processor-sdk-linux-am335x-evm-02.00.00.00-Linux-x86-Install

回复 Lu Simon:
其实就是一个启动脚本，就自己手动分区也可以，效果一样！

回复 yunbo zhang:
非常感謝!!

回复 Lu Simon:
如果脚本执行不成功，可以手动执行下，看看哪里出的问题，有可能是权限不够。

前提：
1. SDK版本:ti-processor-sdk-linux-am335x-evm-04.03.00.05
2. 硬件版本:BBB REV C
3.SD卡（MMC0）启动系统一切正常，
Q:现在打算将SD卡中的程序烧写到EMMC，遇到了楼上一样的问题
在执行./debrick.sh其中的一段脚本时，
sfdisk -D -H 255 -S 63 -C $CYLINDERS $DRIVE << EOF,9,0x0C,*10,,,-EOF报错sfdisk: invalid option — 'D'
sfdisk工具已经不支持-D的option了？
我单独执行
sfdisk -D -H 255 -S 63 -C $CYLINDERS $DRIVE << EOF,9,0x0C,*10,,,-EOF 也报同样的错。希望能有回复，谢谢！
