# 2 编写SDcard.c

# 3 编译烧录

#问题
发现之前的rw007没初始化，找了一下原来是之前在board文件夹没有编译进去
SConscript里面添加一下内容

```asp
from building import *

cwd = GetCurrentDir()

# add the general drivers
src = Split("""
    board.c
    rtt_board.c
    pinmux.c
    fal_flash_port.c
    hpm_wm8960.c
    rw007_port.c  //添加这行
""")

CPPPATH = [cwd]
CPPDEFINES=['D45', 'HPM6750']

group = DefineGroup('Board', src, depend = [''], CPPPATH = CPPPATH, CPPDEFINES = CPPDEFINES)

Return('group')

```
之后编译烧录就行了
