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).
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
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.

Stefan
