Guys,

I tried to use SPI2 and FATFs on STM32CubeMX, but I found two files with the same function, which one should I modify to make it work ?

thanks

Hi h.rick,

I'd highly recommend you to have a look to the

http://www.st.com/st-web-ui/static/active/en/resource/technical/document/user_manual/DM00104712.pdf?s_searchtype=keyword

User manual

In theâ€� B.3.4 FatFsâ€� paragraph it said â€œthe user shall select the FatFs user-defined mode and update the user_diskio.c driver file generated

to implement the interface between the middleware and the selected peripheral.â€�

so I must move all of these to user_diskio.c ?

Thanks for your suggestion

How can I connect this function to my user_diskio.c ? Which function should I call from there ? user_disk_initialize() ? thanks

void MX_FATFS_Init(void) 
{
/*## FatFS: Link the USER driver ###########################*/
retUSER = FATFS_LinkDriver(&USER_Driver, USER_Path);
/* USER CODE BEGIN Init */
/* additional user code for init */ 
/* USER CODE END Init */
}
