Beaglebone spidev problem

Hi all, I'm using beagle bone rev A3 with Sitara sdk (version: ti-sdk-am335x-evm-05.05.00.00).

I need to uso the spi1 with my AD peripheral and I would like to access it at user level. As far I understood from the previous post ( http://e2e.ti.com/support/dsp/sitara_arm174_microprocessors/f/791/p/168122/699213.aspx#699213 ) I've to do it in two step:

1) modify the file board-am335xemv.c file I've added:

static struct spi_board_info am335x_spi1_slave_info[] = {
    {
//        .modalias      = "m25p80",
        .modalias      = "spidev",            //brt
        .platform_data = &am335x_spi_flash,
        .irq           = -1,
        .max_speed_hz  = 1000000,
        .bus_num       = 2,
        .chip_select   = 0,
        .mode = SPI_MODE_0,
    },
};

/* Module pin mux for SPI flash */
static struct pinmux_config spi1_pin_mux[] = {
    {"mcasp0_aclkx.spi1_sclk", OMAP_MUX_MODE3 | AM33XX_PULL_ENBL
        |  AM33XX_PIN_OUTPUT },
    {"mcasp0_fsx.spi1_d0", OMAP_MUX_MODE3 | AM33XX_PULL_ENBL
        | AM33XX_PULL_UP |  AM33XX_PIN_OUTPUT },
    {"mcasp0_axr0.spi1_d1", OMAP_MUX_MODE3 | AM33XX_PULL_ENBL
        | AM33XX_INPUT_EN},
    {"mcasp0_ahclkr.spi1_cs0", OMAP_MUX_MODE3 | AM33XX_PULL_ENBL
        | AM33XX_PULL_UP |  AM33XX_PIN_OUTPUT },
    {NULL, 0},
};

/* setup bone spi1 */
static void bone_spi1_init(int evm_id, int profile)
{
        pr_info("BRT:Beagle bone SPI init\n");
    setup_pin_mux(spi1_pin_mux);
    spi_register_board_info(am335x_spi1_slave_info,
            ARRAY_SIZE(am335x_spi1_slave_info));
    return;
}

/* Beaglebone Rev A3 and after */
static struct evm_dev_cfg beaglebone_dev_cfg[] = {
    {tps65217_init,    DEV_ON_BASEBOARD, PROFILE_NONE},
//    {mii1_init,    DEV_ON_BASEBOARD, PROFILE_NONE},
    {usb0_init,    DEV_ON_BASEBOARD, PROFILE_NONE},
    {usb1_init,    DEV_ON_BASEBOARD, PROFILE_NONE},
    {mmc0_init,    DEV_ON_BASEBOARD, PROFILE_NONE},
    {i2c2_init,    DEV_ON_BASEBOARD, PROFILE_NONE},
    {bone_spi1_init,DEV_ON_BASEBOARD, PROFILE_NONE},        //brt
    {NULL, 0, 0},
};

2) reconfigure the kernel to:

 -enabling ==> User mode SPI device driver support (SPI_SPIDEV)

-disabling ==> McSPI driver for OMAP (SPI_OMAP24XX)

-disabling ==> Memory Technology Device (MTD) support (MTD)

I have successusfully recompiled the kernel and  I was able to see sys files:

root@am335x-evm:~# find /sys -name "*spi*"
/sys/bus/spi
/sys/bus/spi/drivers/spidev
/sys/class/spi_master
/sys/class/spidev
/sys/module/spidev

But I cannot still found the /dev/spidev* devices...

Am I missing something? Where am I wrong?

Many thanks in advance

But still we ca
