3.5 Building boot.img
boot.img and boota are default booting commands.
As outlined in
Running the Android Platform with a Prebuilt Image , we use boot.img and boota as default commands to boot
instead of the uramdisk and Image we used before.
Use this command to generate boot.img under Android environment:
# Boot image for i.MX 8M Nano EVK board
$ source build/envsetup.sh
$ lunch evk_8mn-userdebug
$ make bootimage -j4
For other platforms, use lunch <buildName-buildType> to set up the build configuration. For detailed build configuration, see
Section 3.2 "Building Android images".
3.6 Building dtbo.img
Dtbo image holds the device tree binary of the board.
To generate dtbo.img under the Android environment, use the following commands:
# dtbo image for i.MX 8M Nano board
$ source build/envsetup.sh
$ lunch evk_8mn-userdebug
$ make dtboimage -j4
For other platforms, use lunch <buildName-buildType> to set up the build configuration. For detailed build configuration, see
Section 3.2 "Building Android images".
