WebFatFs does not run efficiently on NAND without flash translation layer. Because of the large size of erase sector (128KB is very common these days), a naive port of FatFs on NAND will wear out the first sector (frequent FAT updates) and run dramatically slow (when individual 512 bytes sector are updated by copying a whole 128KB erase block). WebLast, the STM32CubeMX tool offers a firmware library. Users can call the functions to accelerate development. And your code may well be consistent with the full range of STM32 MCU code. The STM32CubeMx also provides a graphical view for the GPIO, peripherals, clock and so on, fast generating C code for initialization.
