Please check your kernel boot parameters on u-boot.

The below is a part of your kernel log, but Kernel command is not proper to boot with mmc0

Built 1 zonelists in Zone order, mobility grouping on.  Total pages: 227328   

Kernel command line: console=ttymxc0,115200 setenv bootargs ${bootargs} root=/d4

Make sure the SD card you are using is NOT write protected.  The default mount command

for SD cards (in uboot) use the "rw" option.  If the card is write protected, the mount will

fail and give you this same error message.  While this may not be your problem, it is certainly

easy to test

Please recheck SD-card IOMUX configuration, I solve similar problem with follow configuration, thanks Weidong from technical support :

/* ESDHC1 WP */

_MX53_PAD_DI0_PIN4__ESDHC1_WP |

    MUX_PAD_CTRL(PAD_CTL_HYS | PAD_CTL_PKE | PAD_CTL_PUE | PAD_CTL_PUS_360K_DOWN |

                                   PAD_CTL_DSE_HIGH | PAD_CTL_SRE_FAST)

If I use PAD_CTL_PUS_100K_UP I can't mount rootfs with follow error:

Hi Kirill,

   Thanks for your response. I will check it out. I loaded the rootfs files from freescale website and the EVB is up and running. How to i export and set values to GPIO's in Linux. If there is any document kindly share.

Thanks in advance

[BrilliantovKiri]

Hello!

If you Linux configured found rootfs on SD-card please check what your Linux builded with MMC support, MMC support should be enabled in not modules mode.

Also please check what you can work with SD-card from U-Boot and Linux configure SD-card pins.

[vishvapathi]

Hi Kirill,

Thanks for your response. But wat did u mean by "not module mode"???

during start up in console

mmc0: new high speed DDR MMC card at address 0001
mmcblk0: mmc0:0001 SEM08G 7.39 GiB
wm8962 0-001a: customer id 0 revision D
mmcblk0boot0: mmc0:0001 SEM08G partition 1 2.00 MiB
mmcblk0boot1: mmc0:0001 SEM08G partition 2 2.00 MiB
mmcblk0: unknown partition table
mmcblk0boot1: unknown partition table

mmcblk0boot0: unknown partition table

getting these. Does this mean anything wrong with my SD.  while i am able to view the rootfs files when i connect to linux host
