Hi all,

I am working on IMX6q custom board.

I am using IMX6 android4.3 BSP from freescale

when setting sd4 for micro sd , i got mmc timeout message

and i can't mount sd crad on my system

Board.c

#define SD4_CD IMX_GPIO_NR(4, 23)

/* SD4 */

static const struct esdhc_platform_data mx6q_sd4_data __initconst = {

.cd_gpio = SD4_CD,

.keep_power_at_suspend = 1,

.cd_type = ESDHC_CD_CONTROLLER,

.runtime_pm = 1,

};

REGULATOR_SUPPLY("vmmc", "sdhci-esdhc-imx.2"),

REGULATOR_SUPPLY("vmmc", "sdhci-esdhc-imx.3"),

};

( setting sd4 to mmc1 )

imx6q_add_sdhci_usdhc_imx(3, &mx6q_sd4_data);

Hi tsai derek,

What's about your hardware design? The SD4 is connected to emmc or sd? Are you refer to our reference design board MCIMX6Q-SDP/MCIMX6Q-SDB?
Have a great day,
Dan

I am facing similar issue in my i.mx6Q design.

Did this get resolved ?

I see something similar, u-boot can read the SD card without issue

But when the kernel tries to mount the file system, I see

mmc2: Timeout waiting for hardware interrupt.

mmcblk2: error -110 sending status command, retrying

I also have a very similar issue,

getting the same message after mount, after first cmd 18.
