Linux: SD card detected issue

Byron Tien

Other Parts Discussed in Thread: DM385

Tool/software: Linux

Hi all,

I have a custom board with DM385 and  I am running 2.6.37 kernel. 

My problem is that the kernel doesn't detect the SD Card when its booting.

Following are the debug messages for MMC.

Could someone point me to which file to modify? or Is there a flowchart of kernel file chain that would show me which file/function linux kernel calls?

    Hi Sir,

    We have the two custom boards.one board connect the micro sd card.another connect general sd card.The MMC configuration of them are MMC0/wifi and MMC1/sd card. Hardware of MMC design are the same.

    The board with micro sd have the wifi module and another one have no wifi module temporality.it was reserved in the future.

    our mmc information are as below.

    static struct omap2_hsmmc_info mmc[] = {
    {
    .mmc = 1,
    .caps = MMC_CAP_4_BIT_DATA | MMC_CAP_POWER_OFF_CARD,
    .gpio_cd = -EINVAL,
    .gpio_wp = -EINVAL,
    .ocr_mask = MMC_VDD_165_195,
    .nonremovable = true,
    },
    {
    .mmc = 2,
    .caps = MMC_CAP_4_BIT_DATA,// | MMC_CAP_NEEDS_POLL,
    .gpio_cd = -EINVAL, /* Dedicated pins for CD and WP */
    .gpio_wp = -EINVAL,
    .ocr_mask = MMC_VDD_33_34,
    },
    {} /* Terminator */
    };

    We upgrade the same firmware in them.

    After booting,the SD card can be detected in micro sd card board but can not work in sd card board.but it worked in the uboot mode.because I can update the firmware.

    The kernel message of micro sd card board are as below.
