Configure SPI FLASH MX25LX

I can’t find in the documentation how to configure the board assembly files to use SPI FLASH RAM MX25Lx. I tried by analogy with configuring eeprom in crazyflie, but something does not work. Maybe someone set up something like this and can tell you how to do it?
I add mtd.cpp

static const px4_mft_device_t spi2 = {
	.bus_type = px4_mft_device_t::SPI,
	.devid    = SPIDEV_FLASH(0)
};


static const px4_mtd_entry_t mx25_fram = {
	.device = &spi2,
	.npart = 2,
	.partd = {
		{
			.type = MTD_MFT,
			.path = "/fs/mtd_mft",
			.nblocks = 32
		},
		{
			.type = MTD_PARAMETERS,
			.path = "/fs/mtd_params",
			.nblocks = 32
		}
		
	},
};


static const px4_mtd_manifest_t board_mtd_config = {
	.nconfigs   = 1,
	.entries = {
		&mx25_fram
	}
};

static const px4_mft_entry_s mtd_mft = {
	.type = MTD,
	.pmft = (void *) &board_mtd_config,
};

static const px4_mft_s mft = {
	.nmft = 1,
	.mfts = &mtd_mft
};

const px4_mft_s *board_get_manifest(void)
{
	return &mft;
}

in defconfig

ONFIG_MTD=y
CONFIG_MTD_MX25LX=y
CONFIG_MTD_BYTE_WRITE=y
CONFIG_MTD_PARTITION=y

in spi.cpp
