About

update.img is Rockchip's closed image format for nand flash images, which can be flashed via the rockchip batch tool into nand flash.

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.

   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.
