Part Number: PROCESSOR-SDK-AM335X

I have follow the steps : e2e.ti.com/.../503009

everything is fine when I got the step 6:

6. Copy the root file system to the second partition:
# mkdir root
# mount /dev/mmcblk1p2 root
# tar -xf tisdk-rootfs-image-am335x-evm.tar.gz -C root
# umount root

tar is crash. I am sure the file "tisdk-rootfs-image-am335x-evm.tar.gz" is OK. becasue I use this file to create the SD card. It can boot.

    Hello,

    Thanks for you post. Would you please verify which version of the SDK you are working with?

    Could you please provide the output of the command as you execute them?

    Have you verified that the partition that you are trying to copy to is large enough to accept the files?

    Thank you.

    But I also can not boot from eMMC. Boot programe excutes till uboot, fail to boot Linux kernel. And I found I miss the file "uEnv.txt".

    How can I get the file "uEnv.txt"?

    Are you doing this process on a Beaglebone Black? Or, a custom board? If custom, please tell me which MMC slots the SD card and the eMMC are connected to.

    Thanks.

    Hi RonB:

    It is on a Beaglebone Black.

    Thanks.

    Hi,

    OK, I just went through this on a BBB and I couldn't see what you are seeing. Here is my log:

    U-Boot SPL 2018.01-g9d984f4548 (Apr 06 2019 - 07:42:30)

    The U-Boot version you are using is older than mine, so that could be the difference. 

    Can you try to run "mmc dev 1" and mmc info and show the results here. This is what I get:

    => mmc info
    Device: OMAP SD/MMC
    Manufacturer ID: 70
    OEM: 100

    Erase Group Size: 512 KiB
    User Capacity: 3.6 GiB
    Boot Capacity: 2 MiB ENH
    RPMB Capacity: 512 KiB ENH

    I hope this helps.

    Hi RonB:
    Thank you for your help .
    I will try to get the u-boot which you have successful booted.

    This is output from my console :

    => mmc info
    MMC: no card present

    I think I should re-config the u-boot.

    Thanks.
