    Hello Tejas,

    Probably the SD card is write protected or damaged. Have you tried another SD card?

    Best regards,
    Kemal

    Which board and SDK version are you using? Is the behaviour seen on all SDK versions? Is your card holder pins properly aligned and making good contact with the SD card?

    Hi,
    I am using DM8168 custom board. mmc working on 2 boards but other boards mmc can not detect mmc0: error -110 whilst initialising SD card error comes.

    Thanks

    You might want to enable debug for mmc drivers. Do a make menuconfig and somewhere in 'drivers' you can select mmc and there is an option to enable debug. That might help figure out what is going on.

    Looking in errno.h, a -110 is defined as ETIMEDOUT. The error message you see comes from drivers/mmc/core/mmc.c. So it probably means that omap_hsmmc.c is timing out somewhere.
