I am building the android source code and getting new system.img . I try to flash the new system.img on a device and I see that I need another file called boot.img. What is this file ? what is used for ? how can I get it for my device ?

推荐答案

的boot.img包含内核和ramdisk，需要加载该设备的文件系统可以安装前的重要文件。你必须使用生成自己mkbootimg的boot.img文件，由AOSP提供的一个工具。

boot.img contains the kernel and ramdisk, critical files necessary to load the device before the filesystem can be mounted. You have to generate the boot.img yourself using mkbootimg, a tool provided by AOSP.
