I got below error when I build the mss program. I modified the automotive lab demo mrr's source code by adding qspiflash API. And included qspiflash driver headerfile qspiflash.h in both mss_mrr.h and mss_main.c, but still get below error.

From the build log, it seems the qspiflash lib could not be linked.
Can you please check why this issue happens?
