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

$ 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/

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.
    • 编译VIM3时，选择 kvim3-userdebug.
    • 编译VIM3L时，选择 kvim3l-userdebug.
  • TARGET 应该为kvim3或kvim3l
