網上搜到一個叫eMMC Brickbug Check的apk

啟動后里面的Check Memory一項提示要root,但是系統已經是root過的了，不知道如何使用,有知道的請告知。

後來請教做這塊的前同事，得知原始碼包下有自帶測試工具叫badblocks

• 原始檔：

external/e2fsprogs/misc/badblocks.c

• Android.mk:

badblocks_src_files := \
    badblocks.c
LOCAL_SRC_FILES
 
 := $(badblocks_src_files)
LOCAL_C_INCLUDES := $(badblocks_c_includes)
LOCAL_CFLAGS := $(badblocks_cflags)
LOCAL_SHARED_LIBRARIES := $(badblocks_shared_libraries)
LOCAL_SYSTEM_SHARED_LIBRARIES := $(badblocks_system_shared_libraries)
LOCAL_MODULE := badblocks
LOCAL_MODULE_TAGS := optional

include $(BUILD_EXECUTABLE)
 

預設是不編譯的，可以新增：

diff --git a/device.mk b/device.mk
