Is possible to create a file in the SDCARD using only this function?

Consider that the SDCARD was recognized. Mode SPI.SD_CD        => PB7SPI1_MOSI => PA7SPI1_SCK   => PA5SPI1_MISO => PA6 #spi-sd-card-mmc-stm32f103

Well it's NOT going to be a FILE

You can write runs of linear data any way you want, it won't be generally readable by anyone else.

Yes, you'll need to layer something like FatFs on top of the block IO routines to support a FAT12/FAT16/FAT32 partitioned drive.
