报错内容：

Module: can't find led1\_on in kernel symbol table

Module: can't find rt\_thread\_delay in kernel symbol table

平台是STM32F767正点原子阿波罗，IAR编译主程序，icf文件已经添加keep \{ section RTMSymTab \};

编译产生的rtthread.map文件可以找到

\_\_rtmsym\_rt\_thread\_delay

0x0804116c 0x8 Data Gb thread.o \[1\]

\_\_rtmsym\_rt\_thread\_delay\_name

模块的rtconfig.py如下

\# add target option

if GetOption('type') == 'ext':

linkflags = rtconfig.LFLAGS + ' -e 0'

else:

linkflags = rtconfig.LFLAGS + ' -e main'

CPPPATH = GetCPPPATH(BSP\_ROOT, RTT\_ROOT)

env = Environment(tools = \['mingw'\],

AS = rtconfig.AS, ASFLAGS = rtconfig.AFLAGS,

CC = rtconfig.CC, CCFLAGS = rtconfig.CFLAGS,

CXX = rtconfig.CXX, AR = rtconfig.AR, ARFLAGS = '-rc',

LINK = rtconfig.LINK, LINKFLAGS = linkflags,

CPPPATH = CPPPATH)

env.PrependENVPath('PATH', rtconfig.EXEC\_PATH)

PrepareModuleBuilding(env, RTT\_ROOT, BSP\_ROOT)

app = GetOption('app')

if app:

objs = SConscript(os.path.join(app, 'D:/rt-thread\_dev/rt-thread/examples/module/basicapp/SConscript'))

TARGET = os.path.join(app , app + '.' + rtconfig.TARGET\_EXT)

\# build program

target = env.Program(TARGET, objs)

env.Command("$TARGET", target, action = Copy(program\_dir, TARGET))

确定rt\_system\_module\_init函数运行到了下面代码：

\#elif defined (\_\_IAR\_SYSTEMS\_ICC\_\_)

\_rt\_module\_symtab\_begin = \_\_section\_begin("RTMSymTab");

\_rt\_module\_symtab\_end = \_\_section\_begin("RTMSymTab");

\#endif

rtua.y是自动生成的。

确定报错函数是这个

static struct rt\_module \*\_load\_shared\_object(const char \*name,

void \*module\_ptr)

求教下一步怎么查？
