hi，have you ever solved the problem？ I have the same trouble,

can any help me?

Hi all,

I've the same problem using a custom board with iMX6Solo.

The same HW works fine with kernel 3.0.35 but after switching to 3.10.17 I'm facing this issue.

* on 3.0.35 I have:

#define SD1_CD IMX_GPIO_NR(1, 1)

#define SD1_WP IMX_GPIO_NR(1, 9)

static const struct esdhc_platform_data mx6q_sd1_data __initconst = {

  .cd_gpio = SD1_CD,

  .wp_gpio = SD1_WP,

  .keep_power_at_suspend = 1,

  .support_8bit = 1,

  .delay_line = 0,

  .platform_pad_change = plt_sd3_pad_change,

  //.cd_type = ESDHC_CD_CONTROLLER,

};

On 3.10.17 I should apply the same settings through the dts file.

Do you know how should I set cd-gpios and wp-gpios?

&usdhc1 {

  pinctrl-names = "default";

  pinctrl-0 = <&pinctrl_usdhc1_1>;

  fsl,delay-line;

  fsl,cd-controller;

cd-gpios = <&gpio1 1 1>;        

/* cd-inverted;*/

wp-gpios = <&gpio1 9 1>;

/* max-frequency = <50000000>;*/

  keep-power-in-suspend;

// enable-sdio-wakeup;

// cap-sd-highspeed;

//    no-1-8-v;

  status = "okay";

};

Thanks in advance.

Hello Angelo,

Did you solve that problem?

I encountered your same issue: my eMMC memory no longer works properly switching from kernel 3.0.35 to 3.10.17 (or 3.10.53).

Thanks in advance.

Hello Igor,

in my case, the problem was strictly related to an external SD card.

BTW, it was not a SW problem - in fact, I found that with some SD card devices the issue was not reproducible.

Regards,

Angelo

Hello Angelo,

Thanks a lot for your fast reply.

Yesterday I received a new firmware release for that eMMC/SD: now it works properly with both new Linux Kernel Versions!

Regards,

Igor

Hi Igor,

I'm also facing the same kind of problem on my eMMC.

Platform detail: i.Mx6 SabreSD based custom board

Kernel: L3.0.35

Issue is, mmcblk2: error -110 sending stop command, original cmd response 0x900, card status 0x400e00

It's stopped after the issue (console also not alive)

What may be the issue ?

At the same time,

Where will get that latest firmware ? and How to update that (procedure or document)?

Thanks in Advance

Regards,

J.P.Raja

SD2_DAT0 and SD2_DAT1 just can  work.

i will create new thread for uSDHC 1bit mode configuration

[pfsang]

hi, chipexpert

   but my sd card is  SD2.0 8G and is ok on sarbresd

[igorpadykov]

Hi fang,

suggest to test SD2 hardware with bare metal SD read/write test

"MX6_PLATFORM_SDK "

http://www.freescale.com/webapp/sps/site/prod_summary.jsp?code=i.MX6Q&nodeId=018rH3ZrDRB24A&fpsp=1&t...

You can run it with jtag.

Best regards

hi, chipexpert

       i have found the problem which is hardware issue.

       SD2_DAT0 and SD2_DAT1 can work.

       so how do i set the mode to 1bit mode?

[igorpadykov]

Sorry fang

do you mean

"SD2_DAT0 and SD2_DAT1 can NOT work." ?

For uSDHC 1bit mode configuration,

I think you should create new thread, since this is new

problem.

Best regards

[igorpadykov]

Hi fang,

please look below thread with similar SD errors,

seems changing card solved problem

Boot problem: MCIMX6Q-SDB

hi, chipexpert

     i have tried to change three cards, but the problem still is not solved.

[JackyAtFreescal]

Hi fang,

Could you try another SD port?

The problem may be came from the SD port socket.

Regards,

Jacky

[pfsang]

hi, Jacky

   we have only one sd slot  on our board.

   how to  the SD port socket ?

B&R

[igorpadykov · Accepted solution]

Hi fang,

simply put, your card outputs data

so fast, that OS just can not able to receive them.

Suggest to try more slower grade cards or

test old SD2.0 2GB SD card just for test.

Best regards

JackyAtFreescale, could you please look after this SD card issue?
