Hi Chirag garg,
Thanks for your help. I tried to build your hw_sabrelite_tz_support
branch as follow:
RUN_OPT="--target uboot" make run/tz_vmm_mx6
Then it was success and result an image in var/run/tz_vmm_mx6/image.elf.
I converted it to binary:
/usr/local/genode-gcc/bin/genode-arm-objcopy -O binary
var/run/tz_vmm_mx6/image.elf var/run/tz_vmm_mx6/sabrelite.bin
After copied sabrelite.bin to sdcard, I try to boot but it was hang as
below:
Hit any key to stop autoboot: 0
MX6Q SABRESD U-Boot > fatload mmc 2:1 0x10001000 sabrelite.bin
reading sabrelite.bin
17674240 bytes read
MX6Q SABRESD U-Boot > go 10001000
## Starting application at 0x10001000 ...
Please correct me what I am wrong.
Thank you so much,
--Thong Nguyen.

Hello Thong,
It seems, you are trying to run i.mx53 image on the i.mx6 board if
that is the case it will not work. To run the printf script over the
imx6 platform you should try out the latest master branch of Genode on
git hub that have the imx6 support without trustzone.
https://github.com/genodelabs/genode
For the TrustZone support on imx6 SABRE Lite board our team is also
working at IIT Madras , As of now we are able to run Genode(secure
world) beside Genode(normal world) so you can take a look at IIT
Madras repository as the initial starting point.
Genode as secure world :
https://github.com/iitmadras/genode/tree/hw_sabrelite_tz_support
In the hw_sabrelite_tz_support branch tz_vmm_mx6 will work as tz_vmm
Genode as normal world :
https://github.com/iitmadras/genode/tree/hw_sabrelite_tz_normal_os
Switch application in the hw_sabrelite_tz_normal_os branch will serve
you as a linux (for normal world) kernel image in tz_vmm.

Hi all,
I am a newbie in embedded linux system, and my team is starting to
integrate our biometric identification solution into the board
i.MX6Q-SABRESD using Secure OS on Trustzone. After take a research
around, I decide to try start with Genode on imx53_tablet_demo at
https://github.com/skalk/genode/blob/i.MX53_tablet_demo/os/src/server/vmm/imx53/README.
I tried to modify base-hw/src/core/kernel/kernel.cc to add a code line
PDBG("Hello\n") at the beginning of main routine void kernel() and
expected to receive a "Hello" message on my Serial Terminal. I
followed
the instructions in README and be success to build the Genode with
command line:
RUN_OPT="--target uboot" make run/printf
I use pre-built u-boot-mx6dl-sabresd.bin from Freescale.
When I try to boot my Genode build in var/run/printf/ it just
stopped at
