一、下載I2C-tools工具：
最近在移植i2c-tools工具，下載地址：https://i2c.wiki.kernel.org/index.php/I2C_Tools；百度到了wiki中的git地址；
1 git clone git://git.kernel.org/pub/scm/utils/i2c-tools/i2c-tools.git -b i2c-tools-3.1
二、將git下載到external目錄下，編寫Android.mk，將其打包system.img：
Android.mk內容如下：
1 LOCAL_PATH:= $(call my-dir) 2 3 include $(CLEAR_VARS) 4 5 LOCAL_MODULE_TAGS := optional 6 LOCAL_C_INCLUDES += $(LOCAL_PATH) $(LOCAL_PATH)/$(KERNEL_DIR)/include 7 LOCAL_SRC_FILES := tools/i2cbusses.c tools/util.c 8 LOCAL_MODULE := i2c-tools 9 include $(BUILD_STATIC_LIBRARY) 10 11 include $(CLEAR_VARS) 12 13 LOCAL_MODULE_TAGS := optional 14 LOCAL_SRC_FILES:=tools/i2cdetect.c 15 LOCAL_MODULE:=i2cdetect 16 LOCAL_CPPFLAGS += -DANDROID 17 LOCAL_SHARED_LIBRARIES:=libc 18 LOCAL_STATIC_LIBRARIES := i2c-tools 19 LOCAL_C_INCLUDES += $(LOCAL_PATH) $(LOCAL_PATH)/$(KERNEL_DIR)/include 20 include $(BUILD_EXECUTABLE) 21 22 include $(CLEAR_VARS) 23 24 LOCAL_MODULE_TAGS := optional 25 LOCAL_SRC_FILES:=tools/i2cget.c 26 LOCAL_MODULE:=i2cget 27 LOCAL_CPPFLAGS += -DANDROID 28 LOCAL_SHARED_LIBRARIES:=libc 29 LOCAL_STATIC_LIBRARIES := i2c-tools 30 LOCAL_C_INCLUDES += $(LOCAL_PATH) $(LOCAL_PATH)/$(KERNEL_DIR)/include 31 include $(BUILD_EXECUTABLE) 32 33 include $(CLEAR_VARS) 34 35 LOCAL_MODULE_TAGS := optional 36 LOCAL_SRC_FILES:=tools/i2cset.c 37 LOCAL_MODULE:=i2cset 38 LOCAL_CPPFLAGS += -DANDROID 39 LOCAL_SHARED_LIBRARIES:=libc 40 LOCAL_STATIC_LIBRARIES := i2c-tools 41 LOCAL_C_INCLUDES += $(LOCAL_PATH) $(LOCAL_PATH)/$(KERNEL_DIR)/include 42 include $(BUILD_EXECUTABLE) 43 44 include $(CLEAR_VARS) 45 46 LOCAL_MODULE_TAGS := optional 47 LOCAL_SRC_FILES:=tools/i2cdump.c 48 LOCAL_MODULE:=i2cdump 49 LOCAL_CPPFLAGS += -DANDROID 50 LOCAL_SHARED_LIBRARIES:=libc 51 LOCAL_STATIC_LIBRARIES := i2c-tools 52 LOCAL_C_INCLUDES += $(LOCAL_PATH) $(LOCAL_PATH)/$(KERNEL_DIR)/include 53 include $(BUILD_EXECUTABLE)
然後mm命令編譯當前目錄，生成到：
make snod編譯進板子上的system/bin目錄下；
Android下的i2c-tools使用如鏈接所示，就不提及了；
