2011-10-11 03:52:36     cm-bf527 and mmc with spi

Message: 103784   

 

Hello,

 

I'm using CM-BF527 with EVAL-BF5xx board of Bluetechnix.

 

I wanted to use my sd card so that I followed this wep page

 

  docs.blackfin.uclinux.org/doku.php?id=linux-kernel:drivers:spi_mmc

 

After finishing kernel config, I modified linux-2.6.x/arch/blackfin/mach-bf527/boards/cm_bf527.c file like wep page.

 

 

#if defined(CONFIG_MMC_SPI) || defined(CONFIG_MMC_SPI_MODULE)

#define MMC_SPI_CARD_DETECT_INT IRQ_PF5

static int bfin_mmc_spi_init(struct device *dev,

        irqreturn_t (*detect_int)(int, void *), void *data)

{

        return request_irq(MMC_SPI_CARD_DETECT_INT, detect_int,

                IRQF_TRIGGER_FALLING, "mmc-spi-detect", data);

}

 

static void bfin_mmc_spi_exit(struct device *dev, void *data)

{

        free_irq(MMC_SPI_CARD_DETECT_INT, data);

}

 

static struct mmc_spi_platform_data bfin_mmc_spi_pdata = {

        .init = bfin_mmc_spi_init,

        .exit = bfin_mmc_spi_exit,

        .detect_delay = 100, // msecs

};

 

static struct bfin5xx_spi_chip  mmc_spi_chip_info = {

    .enable_dma = 0,

    .bits_per_word = 8,

};

#endif

 

 

#if defined(CONFIG_MMC_SPI) || defined(CONFIG_MMC_SPI_MODULE)

    {

        .modalias = "mmc_spi",

        .max_speed_hz = 20000000,     /* max spi clock (SCK) speed in HZ */

        .bus_num = 0,

        .chip_select = 4,

        .platform_data = &bfin_mmc_spi_pdata,    //

        .controller_data = &mmc_spi_chip_info,

        .mode = SPI_MODE_3,

    },

#endif

 

And I add #include <linux/spi/mmc_spi.h> because error was occurred without this file.

 

then my booting log is like this

Enter 'help' for a list of built-in commands.                                 

 

--------------------------------------------------------------------------------------------------------

 

The error message can be removed by changing .chipselect = 4 to other numbers.

 

However I can't use sd card either and there was no mmcblk0 in /dev

 

 

 

1. What's the .chipselect = 4 and the error message means?

 

2. How could I use my sd card?

 

 

 

 

 

Any advise will be helpful to me.

 

Thanks in advance.

1. chipselect is the SPI channel you select on your SPI MMC daughter board. If you change it to other number, make sure you also change the hardware on your SPI MMC board.

 

2. Insert your sd card into the sd slock on your SPI MMC board. mount the partition on your sd card as described in the wiki document.

Thank you for your advise.

 

In EVAL-BF5xx board, PH9/SPISEL5/ETxD2/HOST_D9/TACLK3 pin(55 of CM-BF527) can be used as chipselect of sd card.

 

So I changed chipselect to 5.

 

Then the booting log was like this.
