Hi. Mypurpose is receive data from usart and write it into file in SD card. I use SDIO 1wire and STM32cube MX. this is my code

#include ''stm32f4xx_hal.h''
#include ''fatfs.h''

uint8_t Rec_Arr[10];

FIL myfile;
unsigned long size;
int sizebuff=512;
unsigned int byte_write;
uint8_t receive_arr[512];

int SignCMD2=0;

but my program don't creat file, I think BSP_SD_Init()==MSD_OK don'tperform!!! Help me !!!

Hi karthy.vain,

CubeMx is a generator of an initialization code. It us up to you to add commands, to create, modify files and do other operations. You need to call appropriate function to achieve your goals. For your purpose, I recommend that you follow  the example ''FATFS_uSD'' in
