快速打包安卓升级固件

这篇文档介绍在只修改部分内容（如uboot和linux）的情况下如何快速打包安卓升级固件而不需要整个完全打包。

准备:

仅仅修改U-boot

  • 重新编译U-boot

    1

    4
    $ cd PATH_YOUR_PROJECT
    $ cd uboot
    $ make CROSS_COMPILE=aarch64-linux-gnu- TARGET_DECONFIG
    $ make CROSS_COMPILE=aarch64-linux-gnu-

  • 拷贝生成的文件到output目录

    5
    $ cd PATH_YOUR_PROJECT
    $ cp uboot/fip/u-boot.bin out/target/product/TARGET/
    $ cp uboot/fip/u-boot.bin.usb.bl2  out/target/product/TARGET/upgrade/
    $ cp uboot/fip/u-boot.bin.usb.tpl  out/target/product/TARGET/upgrade/
    $ cp uboot/fip/u-boot.bin.sd.bin   out/target/product/TARGET/upgrade/

  • 打包固件

    1
    $ ./vendor/amlogic/tools/aml_upgrade/aml_image_v2_packer  -r out/target/product/TARGET/upgrade/aml_upgrade_package.conf  out/target/product/TARGET/upgrade/ out/target/product/TARGET/update.img

  • 重新编译Logo。参考如何编译U-boot Logo。

    4
    $ cd PATH_YOUR_PROJECT
    $ source build/envsetup.sh
    $ lunch TARGET_LUNCH
    $ make logoimg

  • 打包固件

    1
    $ ./vendor/amlogic/tools/aml_upgrade/aml_image_v2_packer  -r out/target/product/TARGET/upgrade/aml_upgrade_package.conf  out/target/product/TARGET/upgrade/ out/target/product/TARGET/update.img

    仅仅修改DTB或kernel

  • 重新编译DTB和kernel

    $ cd PATH_YOUR_PROJECT
    $ source build/envsetup.sh
    $ lunch TARGET_LUNCH
    $ source device/khadas/TARGET/mkern.sh

  • 打包固件

    1
    $ ./vendor/amlogic/tools/aml_upgrade/aml_image_v2_packer  -r out/target/product/TARGET/upgrade/aml_upgrade_package.conf  out/target/product/TARGET/upgrade/ out/target/product/TARGET/update.img

仅仅修改System

  • 重新编译System

    $ cd PATH_YOUR_PROJECT
    $ source build/envsetup.sh
    $ lunch TARGET_LUNCH
    $ make snod
  • 打包固件
    1
    $ ./vendor/amlogic/tools/aml_upgrade/aml_image_v2_packer  -r out/target/product/TARGET/upgrade/aml_upgrade_package.conf  out/target/product/TARGET/upgrade/ out/target/product/TARGET/update.img

注意:

  • 替换’PATH_YOUR_PROJECT’为你自己的项目路径
  • 替换’TARGET_LUNCH’为你自己选择的lunch
  • ‘TARGET’ 应该为kvim或kvim2
  • ‘TARGET_DECONFIG’应还为kvim_defconfig或kvim2_defconfig
