ARM TrustZone Demo in i.MX53 SABRE Tablet

[JaeminPark]

Today, I got Freescale i.MX53 SABRE Tablet and I’d like to make demo as described “Shortcut” in README (https://github.com/skalk/genode/blob/i.MX53_tablet_demo/os/src/server/vmm/imx53/README <https://github.com/skalk/genode/blob/i.MX53_tablet_demo/os/src/server/vmm/imx53/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 https://github.com/skalk/genode/blob/i.MX53_tablet_demo/os/src/server/vmm/imx53/README <https://github.com/skalk/genode/blob/i.MX53_tablet_demo/os/src/server/vmm/imx53/README>

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.

Well, I wonder whether you could boot anything from SD-card on your
tablet (e.g. an image provided by Freescale)? As your u-boot already
hangs when trying to read from MMC.
The things you should investigate: are you sure you interact with the
u-boot from the SD-Card, or maybe the one from the eMMC? You have to
toggle some switches on the board to boot from SD-card.
Next question would be whether mmc 0:1 really targets the SD-Card
instead of an eMMC partition? There are u-boot commands that can help
you, like 'mmcinfo' or something similar.

I really appreciate your kind response.
As you already mentioned, my situation can be addressed by adjusting two switches’ (SW26 and SW28) configuration.
That is, initially my SABRE was not booted using the u-boot on the sdcard.

After this, I got same error situation described in http://comments.gmane.org/gmane.os.genode.devel/3171 <http://comments.gmane.org/gmane.os.genode.devel/3171>.
Based on your answers in same URL, I could fix and now I can execute ARM TrustZone Demon in i.MX 53 SABRE Tablet.

My Best Regards,
Jaemin Park
