你好，我尝试按照SBL_ design中的要求，向程序中加入CANFD，可是我在sbl_internal.h中包含了Canfd.h
#include <ti/drivers/canfd/canfd.h>
再编译出现如下报错，似乎没有找到CANFD的相关源文件。
<Linking>
undefined first referenced
symbol in file
--------- ----------------
CANFD_configBitTime obj_xwr18xx/transport.oer4f
CANFD_createMsgObject obj_xwr18xx/transport.oer4f
CANFD_getData obj_xwr18xx/transport.oer4f
CANFD_init obj_xwr18xx/transport.oer4f
error #10234-D: unresolved symbols remain
error #10010: errors encountered during linking; "xwr18xx_sbl_mss.xer4f" not built
请问这种问题要怎么处理？
