RK3288_Android7.1色温固化的部分移植问题_libsave_baseparameter_util.so

一、编译apk源码后，点击OUTPUT IMAGE，apk闪退
未依赖libcompute_color-jni.so库和libsave_baseparameter_util.so库
解决办法
进入apk源码jni文件夹，mm -B编译生成so库

二、调节好参数后OUTPUT IMAGE fail

这种情况是没找到baseparameter分区，路径/dev/block/platform/ff0f0000.dwmmc/by-name/baseparameter
解决办法
1.确定在/device/rockchip/rk3288/init.rk3288.rc中添加了baseparameter分区信息

# baseparameter
chown system system /dev/block/by-name/baseparameter
chmod 0660 /dev/block/by-name/baseparameter

chown system system /dev/block/platform/ff0f0000.dwmmc/by-name/baseparameter
chmod 0660 /dev/block/platform/ff0f0000.dwmmc/by-name/baseparameter

chown system system /dev/block/mmcblk1p4
chmod 0660 /dev/block/mmcblk1p4

2.修改/device/rockchip/rk3288/parameter.txt中的CMDLINE
我修改了之后，发现这个parameter.txt是拷贝过来的，拷贝路径是/device/rockchip/common/BoardConfig.mk，具体如下:

ifeq ($(strip $(BOARD_BASEPARAMETER_SUPPORT)), true)
    TARGET_RECOVERY_OVERSCAN_PERCENT := 2
    TARGET_BASE_PARAMETER_IMAGE ?= device/rockchip/common/baseparameter/baseparameter_fb1080.img
        PRODUCT_PACKAGES += saveBaseParameter
    ifeq ($(strip $(TARGET_BOARD_PLATFORM)),rk3399)
    LOCAL_POST_PROCESS_COMMAND :=$(shell cp -a device/rockchip/common/parameter_have_baseparameter.txt device/rockchip/rk3399/rk3399_all/parameter.txt)
    TARGET_BASE_PARAMETER_IMAGE := device/rockchip/common/baseparameter/baseparameter_fb1080_3399_all.img
    endif

    ifeq ($(strip $(TARGET_BOARD_PLATFORM)),rk3288)
    LOCAL_POST_PROCESS_COMMAND :=$(shell cp -a device/rockchip/common/parameter_have_baseparameter_3288.txt device/rockchip/rk3288/parameter.txt)
    endif
else
# use the parameter in device/rockchip/rk3399/rk3399_all/
#    ifeq ($(strip $(TARGET_BOARD_PLATFORM)),rk3399)
#    LOCAL_POST_PROCESS_COMMAND :=$(shell cp -a device/rockchip/common/parameter_no_baseparameter.txt device/rockchip/rk3399/rk3399_all/parameter.txt)
#    endif

    ifeq ($(strip $(TARGET_BOARD_PLATFORM)),rk3288)
    LOCAL_POST_PROCESS_COMMAND :=$(shell cp -a device/rockchip/common/parameter_no_baseparameter_3288.txt device/rockchip/rk3288/parameter.txt)
    endif
endif

3.修改/device/rockchip/rk3288/recovery.emmc.fstab，增加信息

/dev/block/platform/ff0f0000.dwmmc/by-name/baseparameter           /baseparameter         emmc             defaults                  defaults
1

4.生成节点文件后，要给定/dev/block/platform/ff0f0000.dwmmc/by-name/baseparameter可执行权限，/device/rockchip/common/ueventd.rockchip.rc

#for baseparameter function
/dev/block/platform/ff0f0000.dwmmc/by-name/baseparameter 0660 system system

最后点击OUTPUT IMAGE，成功生成/sdcard/baseparameter.img

三、将该baseparameter.img打包到升级固件中
/device/rockchip/common/BoardConfig.mk
/device/rockchip/rk3288/BoardConfig.mk

TARGET_BASE_PARAMETER_IMAGE := device/rockchip/common/baseparameter/baseparameter_fb1080.img
1

将sdcard/baseparameter.img生成的固件替换成该目录相应文件名，全编译打包就行了
