我想Android4.2.2环境下编译生成OTA升级全包，但是编译不通过，问题如下：
make TARGET_PRODUCT=beagleboneblack otapackage // 编译命令
============================================
PLATFORM_VERSION_CODENAME=REL
PLATFORM_VERSION=4.2.2
TARGET_PRODUCT=beagleboneblack
TARGET_BUILD_VARIANT=eng
TARGET_BUILD_TYPE=release
TARGET_BUILD_APPS=
TARGET_ARCH=arm
TARGET_ARCH_VARIANT=armv7-a-neon
HOST_ARCH=x86
HOST_OS=linux
HOST_OS_EXTRA=Linux-3.5.0-54-generic-x86_64-with-Ubuntu-12.04-precise
HOST_BUILD_TYPE=release
BUILD_ID=JDQ39
OUT_DIR=out
============================================
__
make: *** No rule to make target `otapackage'. Stop.
请问谁生成过OTA包或者有相关经验，谢谢！
