Hello @NOVAL_______BOBY and welcome to the community,

Need to validate your read / write operation to the SPI Flash memory "W25Qxxx" before implementing FatFs on it.

tried read and write operations worked successfuly but when i try this again 

fres = f_mkfs("0:", FM_FAT, 0, worK, sizeof(worK));

fres = f_mount(&fs,"0:",1);

if(fres == FR_OK) {

v=9;

fres = f_open(&fp, "info.txt", FA_OPEN_ALWAYS|FA_WRITE);

}

else {

v=fres;

}
i got
