I am working stm32l031g6u6 controller and i want to interface external flash using fatfs.
I refer the document by stm Implementation-of-FatFs-on-Serial-Flash- and tested the code but it's not working.
It showing error of FR_NO_FILE SYSTEM. i have modified the diskio.c file as per document but nothing work.
i have attached the main file and diskio.c file.
