No SPI Devices with i.mx6 :/

[sany1984]

Hello,

I am a Raspi User, and i buyed a UDOO Quad Board.

I am running Udoo on Ubuntu.

I will use a RFM70 Module for communicate with other Devices in the Network.

But i have a Problem, i stuck on the SPI Devices.

I have no SPI devices on /dev/....

i recompiled the kernel with SPI Support, but i have no luck....

Can you help me?

Thank you!

Hello,

I am very lucky, when i get Support, or Help.

I have a Udoo Quad Board. I edited the Kernel Source an Compiled it.

Now i get these Errors in kern.log:

Jan  1 00:00:02 udoo kernel: [	0.916505] spi_imx imx6q-ecspi.1: can't get cs gpios
Jan  1 00:00:02 udoo kernel: [	0.921582] spi_imx: probe of imx6q-ecspi.1 failed with error -22

i will use the SPI1 device from my i.MX.

My SPI Code:

/usr/src/kernel/arch/arm/mach-mx6/board-mx6_seco_UDOO.c:

/***********************************************************************

*                               SPI                                   *

        MX6Q_PAD_DISP0_DAT23__ECSPI1_SS0,

        MX6Q_PAD_EIM_D24__ECSPI1_SS2

};

static const struct spi_imx_master mx6q_seco_UDOO_spi_data1 __initconst = {

        .chipselect             = mx6q_seco_udoo_spi_cs1,

        .num_chipselect         = ARRAY_SIZE(mx6q_seco_udoo_spi_cs1),

};

static struct spi_board_info imx6_seco_UDOO_spi_device[] __initdata = {

        {

        .modalias = "spidev",

        .max_speed_hz = 20000000,

        .bus_num = 0,

        .chip_select = 0,

        .mode = SPI_MODE_0,

        },

};

static void spi_device_init(void) {

        spi_register_board_info(imx6_seco_UDOO_spi_device, ARRAY_SIZE(imx6_seco_UDOO_spi_device));

}

Thank you for infos :smileyhappy:
