android7 make otapackage编译
首先修改
device/rockchip/rk3288/BoardConfig.mk
BOARD_USE_SPARSE_SYSTEM_IMAGE := true
TARGET_USERIMAGES_SPARSE_EXT_DISABLED := false
后出现编译报错
Traceback (most recent call last):

修改
device/rockchip/common/recovery.fstab
增加一个vendor分区
/dev/block/rknand_vendor /vendor ext4 defaults defaults
最后能编译生成update.zip文件，但用这个update.zip升级后系统无法启动，目前还不知道什么原因
最后采用了update.img进行升级系统
修改
device/rockchip/rk3288/BoardConfig.mk
BOARD_USE_SPARSE_SYSTEM_IMAGE := false
TARGET_USERIMAGES_SPARSE_EXT_DISABLED := true
这样修改后生成的镜像，可以制作TF卡更新卡，同时也支持recovery更新
修改device/rockchip/rk3288/parameter.txt
MACHINE_MODEL:ease3288
这个MACHINE_MODEL需要和device/rockchip/rk3288/rk3288.mk中PRODUCT_MODEL一样不然无法更新
修改
bootable/recovery/recovery.cpp
在1906行左右增加strcpy(updatepath, update_rkimage);
else
bAutoUpdateComplete=true;
strcpy(updatepath, update_rkimage);//add by leijie
}else if (factory_mode != NULL){
如果不增加这个使用update.img更新后，提示删除的时候无法正常删除update.img文件
修改完成后编译生成update.img文件，拷贝到TF或者U盘根目录，或者内部存储/sdcard/目录下系统就会提示更新
如果是拷贝到内部存储/sdcard/目录下需要重启才会提示更新。
