i.MX8MQ booting error?

I'm using an IMX8MQ EVB and trying to flash new binary including bootloader, kernel and fs to the target.

After flashing Linux images compiled with yocto source code according to the "4.4.1.2 Using eMMC" of "i.MX Linux User's Guide", the following errors are occurred on booting the IMX8MQ EVB board.

What should I do to fix it?

Hi ByungGuk

as i.MX8M EVK emmc is flashed by default with android image, seems for linux usage it should

be repartitioned, one can look at attached mfg tool scripts :

    <!-- create partition -->
    <CMD state="Updater" type="push" body="send" file="mksdcard.sh.tar">Sending partition shell</CMD>
    <CMD state="Updater" type="push" body="$ tar xf $FILE "> Partitioning...</CMD>
    <CMD state="Updater" type="push" body="$ sh mksdcard.sh /dev/mmcblk%mmc%"> Partitioning...</CMD>

    <!-- burn uboot -->
    <CMD state="Updater" type="push" body="$ dd if=/dev/zero of=/dev/mmcblk%mmc% bs=1k seek=4096 conv=fsync count=8">clear u-boot arg</CMD>
    <!-- access boot partition -->
    <CMD state="Updater" type="push" body="$ echo 0 > /sys/block/mmcblk%mmc%boot0/force_ro">access boot partition 1</CMD>
        <CMD state="Updater" type="push" body="send" file="files/imx-boot-imx8mqevk-sd.bin-flash_evk" ifdev="MX8MQ">Sending u-boot.bin</CMD>
    <CMD state="Updater" type="push" body="$ dd if=$FILE of=/dev/mmcblk%mmc%boot0 bs=1k seek=33">write U-Boot to sd card</CMD>
