Booting problem In AM335x EVM using SDKv7.00 using SD card.

Other Parts Discussed in Thread: TPS65910

Hello friends,

      I am new for this platform. Working from last 2 weeks on this but fail to boot the board.

      I am using base board version 1.2A and sdkv7.00.

      Booting my board using SD Card. Using "create_sdcard.sh" script I prepared SD card.

      Coping all images from ti-sdk/board_support/Prebuild-images/ which are given by TI only.

     

below output I am getting.

    Hi Vishal,

    The system can't find your SD card's root partition.

    Please post the sd card creation log. It should be run with sudo from inside the <sdk>/bin/ folder.

    Do you use the filesystem that comes with SDK 07.00.00.00? The zImage should be located on the /root partition inside /boot folder.

    Best regards,
    Miroslav

    Hi Miroslav,

          SD Card creation log means ?? I didn’t get what exactly . I run "create_sdcard.sh" script.

          ti-sdk/bin sudo ./create-sdcard.sh 

          Yes, I am using same filesystem which I got with SDKv7. zImage is in /rootfs/boot .

           inside rootfs/boot  other .dtb files are also present. eg :devicetree-zImage-    .dtb and am335x-evm.dtb etc

     

          Regards

          Vishal

    I meant the log messages in your Terminal during the execution of the create-sdcard.sh script.

    Vishal,

    Everything seems correct during the SD card creation. Can you try a different SD card and see if the system will detect and mount the root partition?

    Best regards,
    Miroslav

    Hello Miroslav,

        I try with 3 SD cards. With 2 different SDK versions SDKv7, SDKv5.3 (this I get with EVM-KIT ).

        Every time with every combination of SD card and SDK  booting process get stuck at same point.

        Regards

    hi Miroslav,

         While running "setup.sh" script in starting we get some messages.

    ////////  part of setup.sh script log /////////////////////////////////////////////////////////////////////////////

    This step will set up the SDK to install binaries in to:
        /home/vishal/ti-sdk-am335x-evm-07.00.00.00/targetNFS/home/root/am335x-evm

    The files will be available from /home/root/am335x-evm on the target.

    This setting can be changed later by editing Rules.make and changing the
    EXEC_DIR or DESTDIR variable (depending on your SDK).
    /////////////////////////////////////////////////////////////////////////////////////////////////////////////////////

    In above message " EXEC_DIR or DESTDIR variable " when we have to change these variables??

    Presently I am not making changes. Why changes are required??

    Regards

    Vishal

    Vishal,

    You don't need to modify any variables in order to boot our EVMs with the pre-built binaries that come with our SDK.

    I reproduced your issue with the following steps:

    1) Boot from SD card.

    2) After kernel is loaded and starts booting remove the SD card.

    3) The system is stuck on the following boot message: "Waiting for root device /dev/mmcblk0p2..."

    4) If I reinsert the SD card, the system continues to boot.

    This leads me to believe that you may have a hardware issue, e.g. a bad contact. Try to remove and insert the SD card when your system is stuck to see if it will be detected.

    Best regards,
    Miroslav

    Hi Miroslav,

        Thanks for helping me.

         Please check this link

         http://processors.wiki.ti.com/index.php/Sitara_Linux_SDK_Release_Notes.

          Supported Devices

    • AM335x EVM PG 2.1
    • AM335x EVM-SK PG 2.1
    • BeagleBone and Beaglebone Black

           I am using AM335x EVM PG 1.2A with SDKv7.

           But also trying with SDKv5.3. Not working with any one.

         I will check Hardware.

      Thanks

    Hello Guys,

    I'm having the exact same problem - where the boot process stops after "Waiting for root device /dev/mmcblk0p2...". I'm thinking this is more to do with software than hardware. 

    Do you guys have any thoughts on this one? I've attached my log file for reference.

    Thanks a lot for your help.

    Regards

    Hello Everyone,

    I would like to add that when I use the Linux Kernel 3.2 (SDK 06) it seems to work fine.

    Thank you

    Regards

    Hello Guys,

    As indicated in several other posts on the e2e forum - the problem was with the Card detect pin. The pin has to be low for Linux to detect card present.

    The card detect on my hardware had an issue, solved that and now the kernel seems to come up fine. I would like to add a note here....

    Kernel 3.2 seems to work fine even with the card detect issue (that is why I didn't face this issue till now).

    Thanks once again.

    Regards

    Santhosh

    Hi Santhosh,

      At which file I have to make changes, In SDKv7 board.c file is not present they are using dtb files.

      How to make Card detect pin LOW and at which file??

     

     Regards,

     Vishal

    Hello Vishal,


    May be my explanation was not clear - but this is a hardware problem. The signal goes low when the sd card is inserted. The only thing needed in the dts file is to set the correct GPIO as the card detect signal.

    Hello Santhosh,

       I am not able to resolve this problem till. I tried with SDKv6 and v7 both.

       In dts file

    mmc1_pins_default: pinmux_mmc1_pins {
                pinctrl-single,pins = <
                    0x0F0 (PIN_INPUT_PULLUP | MUX_MODE0)    /* mmc0_dat3.mmc0_dat3 */
                    0x0F4 (PIN_INPUT_PULLUP | MUX_MODE0)    /* mmc0_dat2.mmc0_dat2 */
                    0x0F8 (PIN_INPUT_PULLUP | MUX_MODE0)    /* mmc0_dat1.mmc0_dat1 */
                    0x0FC (PIN_INPUT_PULLUP | MUX_MODE0)    /* mmc0_dat0.mmc0_dat0 */
                    0x100 (PIN_INPUT_PULLUP | MUX_MODE0)    /* mmc0_clk.mmc0_clk */
                    0x104 (PIN_INPUT_PULLUP | MUX_MODE0)    /* mmc0_cmd.mmc0_cmd */
                    0x1A0 (PIN_INPUT_PULLUP | MUX_MODE7)    /* mcasp0_aclkr.gpio3_18 */
                    0x160 (PIN_INPUT | MUX_MODE7)        /* spi0_cs1.gpio0_6 */
                >;
            };

       last pin is used for card detection. and it is neither pullup or pulldown.

       Should I change it ??

      I am looking for solution from long back but not able to resolve it. Please help me.

      Regards,

      Vishal.

    Hi,

       I Set  card detect pin 0x160 (PIN_INPUT_PULLUP | MUX_MODE7)        /* spi0_cs1.gpio0_6 */

      as PULLUP in dts file but I dont know how to build it to new dtb file.


       PLz share information about building dts file. I fand doing write changes.


      Regards

    Hi Miroslav,

      I build SDKv7 kernel I got zImage of it.

      when I am trying to build dts file using

     make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- am335x-evm.dtb

     I am getting warnings Mark with red colour.

    For some reason, these files have modification times later than the system time. Have you changed your time/date lately?

    A possible solution is to clean your whole kernel and rebuild it again.

    Another solution is to use the "touch" command on these files, which will update their modification times to the current system time.

    Best regards,
    Miroslav

    Hello Friends,

        I am also able to resolve this problem. It was totally hardware problem.

        SD card detect pin is not getting shorted  with GND i.e Body of SD card cover So push that make short it with

        SD card cover.  

         Regards.
