Make a "Fast Package Update Image"

This guide is about how to make a “Fast Package Update Image”; This means that you will only change one part of Android. For example, only change the U-Boot, Kernel or System.

Preparations:

Only Change the U-Boot

  • Rebuild U-Boot

    $ cd PATH_YOUR_PROJECT
    $ cd bootload/uboot
    $ ./mk TARGET
  • Copy files to output directory

    $ cd PATH_YOUR_PROJECT
    $ cp bootloader/uboot/build/u-boot.bin out/target/product/TARGET/bootloader.img
    $ cp bootloader/uboot/build/u-boot.bin.usb.bl2 out/target/product/TARGET/upgrade/
    $ cp bootloader/uboot/build/u-boot.bin.usb.tpl out/target/product/TARGET/upgrade/
    $ cp bootloader/uboot/build/u-boot.bin.sd.bin out/target/product/TARGET/upgrade/
  • Package Update Image

    $ ./vendor/amlogic/common/tools/aml_upgrade/aml_image_v2_packer  -r out/target/product/TARGET/upgrade/aml_upgrade_package_avb.conf
    out/target/product/TARGET/upgrade/ out/target/product/TARGET/update.img
  • Rebuild Logo Image.(About more informations,You can refer to Build Bootup Logo For U-boot)

    $ cd PATH_YOUR_PROJECT
    $ source build/envsetup.sh
    $ lunch TARGET_LUNCH
    $ make logoimg
  • Package Update Image

    $ ./vendor/amlogic/common/tools/aml_upgrade/aml_image_v2_packer  -r out/target/product/TARGET/upgrade/aml_upgrade_package_avb.conf out/target/product/TARGET/upgrade/ out/target/product/TARGET/update.img

    Only Change the DTB or Kernel

  • Rebuild DTB and Kernel

    $ cd PATH_YOUR_PROJECT
    $ source build/envsetup.sh
    $ lunch TARGET_LUNCH
    $ make bootimage
  • Package Update Image

    $ ./vendor/amlogic/common/tools/aml_upgrade/aml_image_v2_packer  -r out/target/product/TARGET/upgrade/aml_upgrade_package_avb.conf  out/target/product/TARGET/upgrade/ out/target/product/TARGET/update.img

Only Change the System

  • Rebuild System Image
    $ cd PATH_YOUR_PROJECT
    $ source build/envsetup.sh
    $ lunch TARGET_LUNCH
    $ make systemimage
  • Package Update Image
    $ ./vendor/amlogic/common/tools/aml_upgrade/aml_image_v2_packer  -r out/target/product/TARGET/upgrade/aml_upgrade_package_avb.conf out/target/product/TARGET/upgrade/ out/target/product/TARGET/update.img

Note:

  • Replace PATH_YOUR_PROJECT to your project path
  • Replace TARGET_LUNCH to your lunch select.
    • For VIM3, it’s kvim3-userdebug.
    • For VIM3L, it’s kvim3l-userdebug.
