Hi all ,

I am currently with stm32l433, where i am stuck between FatFs file system. There are few things i need to clear.1. Communication between STM32L433 and M25p16 working properly with help of SPI. All read and write operation working .The Problem is : When i am trying to put Fatfs which was generated by CubemX , then i am getting error that ''No File System Found''.So my first Question :1. Is M25P16 Flash supports FatFs (

elm-chan.org/fsw/ff/00index_e.html

)  ?2. If it is supported what will be the steps i need to follow to overcome this problem.3. If it is not supported then, what other File system can i use with my external m25p16 memory device ?

Hi singh.deepak.002, 

You may check in open project source communities like Github : for example this

Unless the flash has been formatted/initialized it is not going to have FAT MBR or BPB data or structures on it. ie No File System

1) Don't know, can you read/write 512 byte sector(s) properly?2)
