I try this to flash Linux to eMMC, but can't boot into Linux and get error as below:

    Hi Johnny,

    If the Linux is already flashed successfully into the eMMC, then can you try the following commands:

    => setenv mmcdev 0
=> setenv bootpart 0:1
=> boot

    Regards,

    Prashant

    Let's do some debugging. Can you post the output of...

    => mmc dev 0
switch to partitions #0, OK
mmc0(part 0) is current device
=> mmc part

    ...as well as...

    => env print

    Regards, Andreas

    Hi Andreas,

    I retry all step in origin reference, and didn't have any error.

    And I found /mnt/temp isn't empty before tar xf <Linux image file copied from the host> at this time.

    I thought maybe I forgot to umount temp at the first time.
