My mx6dl sabre board stop at 'Waiting for root device dev/mmcblk0p2... '

[wenmingfeng]

Hello, 

I have a mx6dl sabresd customer board, when I changed all the pins and make uboot working, It can boot and starting the kernel but stopped at "Waiting for root device dev/mmcblk0p2...", please help me.

Is it a filesystem issue or my board HW not working? the Board I used is customerize from imx6dl sabresd. and boot it from a SD card.

Hi Wenming,

From the u-boot side I think there is no issue. It looks fine to me. But can you please share the pin muxing and device tree changes; you did in the kernel level.

In dtsi file card detect pin should be something like

MX6QDL_PAD_GPIO_1__GPIO1_IO01  0x1f059    /* CD */

Also please have a look in your device tree for the below details :

&usdhc1 {  // As you are using the mmc0 for SD card booting

cd-gpios = <&gpio1 1 GPIO_ACTIVE_LOW>;

bus-witdh=<4>;

}

Thanks,

Vinod

[wenmingfeng]

Thank Vinod,

After I upgrade the kernel to the latest one. rootfs works for my customer board.

[wenmingfeng]

Hi Vinod,

Thanks for your help, I am no lucky.

The dtsi changes I done in attached,  modified the usdhc2 to usdhc1 at line 752, and the CD pin and WP pin is used GPIO_1_IO01 and GPIO_1_IO09 which I changed in the pinctrl_hog. Any thing missed please help.

the uboot console mmc part: 

imx6qdl-sabresd {
pinctrl_hog: hoggrp {
fsl,pins = <
MX6QDL_PAD_NANDF_D0__GPIO2_IO00 0x80000000
MX6QDL_PAD_NANDF_D1__GPIO2_IO01 0x80000000
MX6QDL_PAD_GPIO_1__GPIO1_IO01 0x80000000
MX6QDL_PAD_GPIO_9__GPIO1_IO09 0x80000000
MX6QDL_PAD_GPIO_0__CCM_CLKO1 0x130b0

pinctrl_usdhc1: usdhc1grp {
fsl,pins = <
MX6QDL_PAD_SD1_CMD__SD1_CMD 0x17059
MX6QDL_PAD_SD1_CLK__SD1_CLK 0x10059
MX6QDL_PAD_SD1_DAT0__SD1_DATA0 0x17059
MX6QDL_PAD_SD1_DAT1__SD1_DATA1 0x17059
MX6QDL_PAD_SD1_DAT2__SD1_DATA2 0x17059
MX6QDL_PAD_SD1_DAT3__SD1_DATA3 0x17059
>;
};

&usdhc1 {
pinctrl-names = "default";
pinctrl-0 = <&pinctrl_usdhc1>;
bus-width = <4>;
cd-gpios = <&gpio1 1 0>;
wp-gpios = <&gpio1 9 0>;
no-1-8-v;
keep-power-in-suspend;
enable-sdio-wakeup;
status = "okay";
};

after change the conflicts mutex usage, I got bellow error and kernel panic.

Hi feng,

Please check your SD card detection pin and pin mux for the same (assuming your SD card partitions are correct).

Thanks,

Vinod

Hi Vinod,

Thanks for your response, the CD pin  we used is GPIO_1_IO01, and used as USDHC1_CD_GPIO.

#define USDHC1_CD_GPIO IMX_GPIO_NR(1, 1), I also checked the BOOTCFG2 0xe0,  and BOOTCFG1 0x42, for my start at SD card and with regular speed, 4bits bus, that is correctly. please help to point out steps to do or check pointers to get the root cause.

The SD card has two partitions following Installing Ubuntu Rootfs on NXP i.MX6 boards .  I also use buildroot to build the latest release  rel_imx_4.1.15_2.0.0_ga, then use the sudo dd if=sdcard.img of=/dev/sdx to get the SDcard.

static iomux_v3_cfg_t const usdhc1_pads[] = {
MX6_PAD_SD1_CLK__SD1_CLK | MUX_PAD_CTRL(USDHC_PAD_CTRL),
MX6_PAD_SD1_CMD__SD1_CMD | MUX_PAD_CTRL(USDHC_PAD_CTRL),
MX6_PAD_SD1_DAT0__SD1_DATA0 | MUX_PAD_CTRL(USDHC_PAD_CTRL),
MX6_PAD_SD1_DAT1__SD1_DATA1 | MUX_PAD_CTRL(USDHC_PAD_CTRL),
MX6_PAD_SD1_DAT2__SD1_DATA2 | MUX_PAD_CTRL(USDHC_PAD_CTRL),
MX6_PAD_SD1_DAT3__SD1_DATA3 | MUX_PAD_CTRL(USDHC_PAD_CTRL),
MX6_PAD_GPIO_1__GPIO1_IO01 | MUX_PAD_CTRL(NO_PAD_CTRL), /* CD */
};

Thanks!
