==Generating the image==
===Windows===
A window batch tool is provided by Rockchip to create the image, which calls the AFPTool.exe and RKImageMaker.exe to generate the image. You can find the batch tool at the rockdev folder of the SDK source code.
Afptool -pack ./ Image\update.img
RKImageMaker.exe -RK31 RK3188Loader(L)_V1.24.bin Image\update.img update.img -os_type:androidos

The afptool reads the package-file which contains what files to be packed into the image.
# NAME Relative path
