Today, I got Freescale i.MX53 SABRE Tablet and I’d like to make demo as described “Shortcut” in README ( <>).

After boot-up the tablet, I failed to load image.bin into the device.

It could be a ridiculous question, but please tell me which point I did wrong.

My procedure was as follows :

1) Download image.bin from URL in <>

2) Setup sdcard as follows : (sdcard is mounted in /dev/sdb)
    sudo parted /dev/sdb --script mklabel msdos
    sudo parted /dev/sdb --script mkpart primary ext4 5M 100%
    sudo dd if=$(U-BOOT-DIR)/u-boot.imx of=/dev/sdb seek=2 bs=512 conv=fsync
    sudo fdisk -l /dev/sdb
    sudo mkfs.ext4 /dev/sdb1
    sudo udisks --mount /dev/sdb1
    sudo cp image.bin /media/371a8dd7-58c1-4beb-aed3-cb18fb40f7eb/
    sudo udisks –-unmount /dev/sdb1

3) insert sdcard into MMC adapter, and then insert MMC (sdcard) into the tablet

4) After power up the tablet, U-BOOT prompt (u-boot from MMC is not used), I did as follows :
    MX53-SMD U-Boot > ext2load mmc 0:1 0x70800000 image.bin
    (hang forever)

So, I couldn’t load image.bin into the tablet, thus I couldn’t boot demo image in the tablet.

If possible, (for the beginner in this field) please let me know full procedures to set up the MMC (sdcard) for this demo.
