挂载android只读文件系统为可读写

这个是海思的盒子：

这么才对，先 -s 设备名 ，然后才开始push操作。

看我的MB865

shell@edison:/ $ mkdir zhangbin mkdir zhangbin mkdir failed for zhangbin, Read-only file system 255|shell@edison:/ $

C:\Users\ZhangBin>adb shell

在手机端挂载只读为rw，当然， RE管理器申请了root权限的，然后

shell@edison:/ $ su su root@edison:/ #

哈哈，root啊

root@edison:/data # adb push g:\ffmpeg /data/zhangbin adb push g:\ffmpeg /data/zhangbin * daemon not running. starting it now on port 5038 * * daemon started successfully * error: device not found 1|root@edison:/data # adb push g:\ffmpeg /data/zhangbin adb push g:\ffmpeg /data/zhangbin error: device not found 1|root@edison:/data # exit exit shell@edison:/ $ su

退出，然后在控制台，push，而不是在shell中push。

root@edison:/ # exit exit shell@edison:/ $ exit exit C:\Users\ZhangBin>adb devices List of devices attached 0146A07E02014015        device C:\Users\ZhangBin>adb push g:/ffmpeg /data/zhangbin 3713 KB/s (2939860 bytes in 0.773s) C:\Users\ZhangBin>
