1.  Edit the Makefile and add a source file to it, as shown in the following example:

    ```
    include drivers/hdf/khdf/platform/platform.mk
    
    obj-y  += $(HDF_PLATFORM_FRAMEWORKS_ROOT)/src/i2c_core.o \
              $(HDF_PLATFORM_FRAMEWORKS_ROOT)/src/i2c_if.o \
              ./i2c_adapter.o \
              ./i2c_sample.o
    ```

    **./i2c\_sample.o**  is the source file added to the Makefile in this example.

2.  Build the version and burn the system image to the development board.
