AM5726: Bootable SD card

Part Number: AM5726

I have some problem to create a bootable SD-card for an custom AM5726 board:

I have installed the TI SDK am57xx-evm-linux-rt-sdk-src-06.00.00.07.tar.xz ..

and startet <SDK>/bin/create-sdcard.sh

It has done the following steps:

1. found a 32 GB mmc device

2. create two partinitions

                                             Disk: /dev/sdc
                           Size: 29.8 GiB, 32010928128 bytes, 62521344 sectors
                                   Label: dos, identifier: 0x2724ff83

    Device          Boot             Start          End      Sectors      Size     Id Type
>>  /dev/sdc1       *                 2048       145407       143360       70M      c W95 FAT32 (LBA)    
    /dev/sdc2                       145408     62488575     62343168     29.7G     83 Linux
    Free space                    62488576     62521343        32768       16M

3. It had installed the pre-built images form SDK

If I start the device with SD-Card the device will restart because it found nothing to boot. The same on the TI-EVM board.

I can mount both partition and I can see the "rootfs" and "boot" with some content like MLO, u-boot.img and uEnv.txt and in "rootfs" a linux filesystem structure .. whats wrong?
