从SD卡启动后怎么烧写emmc
各位大大：板子的直接recovery进不去了，可以从sd卡启动，以及sd卡启动下进入recovery模式，但是用开发工具进行烧写都是烧写到SD卡，请问怎么能在SD卡启动的情况下烧写EMMC？
谢谢！ 你的 recovery ， 是指 loader 模式吧？
从 SD 卡启动进入系统后，执行：
dd if=/dev/zero of=/dev/mmcblk0
清空 eMMC Flash 。拔掉 SD 卡， eMMC 就可以进入 loader 模式了，也就可以升级了。 busybee 发表于 2015-5-13 17:47

是指loader模式。
但是我的adb shell报错：- exec '/system/bin/sh' failed: No such file or directory (2) -
所以还没进得了系统。
有串口适配器吗？ 试一下从串口终端访问。
不过也够奇怪的， /system/bin/sh 怎么会没有呢？
如果 SD 卡的 Android 固件不行，可以试一下 SD 卡的 Linux 固件。 串口也进不去啊，看了打印是kernel起来后又从EMMC挂载了分区，而SD卡上只找到一个分区，不知道是什么原因？
