Hello,
I'm trying to boot genode on the secure world and linux on normal world of
the iMX53-QSB board (freescale).
The problem I'm encountering is:
[init -> tz_vmm] Start virtual machine ...
and then various errors, either it hangs, or
undefined instruction, or
Pagefault in core thread (pager_activation): ip=70055228 fault=20ef8904
failed to communicate thread event
My steps leading to this:
Downloaded http://genode.org/files/images/imx53_qsb/initrd.gz
and cloned https://github.com/skalk/linux.git
git checkout imx53-tz
Kernel compile:
using
http://www.codesourcery.com/sgpp/lite/arm/portal/package4573/public/arm-none-linux-gnueabi/arm-2009q1-203-arm-none-linux-gnueabi.bin
make CROSS_COMPILE=/opt/codesourcery/bin/arm-none-linux-gnueabi- ARCH=arm
imx5_android_tz_defconfig
make CROSS_COMPILE=/opt/codesourcery/bin/arm-none-linux-gnueabi- ARCH=arm
uImage
copied the initrd and uImage into the micro sd card, changed the name of
uImage into linux
I cloned https://github.com/genodelabs/genode.git
working on the master branch, current commit hash: 54ef87c
Created build directory:
tool/create_builddir hw_imx53_qsb_tz BUILD_DIR=hw_imx53_qsb_tz
I added "SPECS += trustzone" to etc/specs.conf in the build directory
Compiled:
make run/tz_vmm
Created u-boot image:
/opt/gcc-linaro-arm-none-eabi-4.9-2014.09_linux/bin/arm-none-eabi-objcopy
-O binary var/run/tz_vmm/image.elf var/run/tz_vmm/image.bin
mkimage -A arm -O linux -T kernel -C none -a 0x70010000 -e 0x70010000 -d
var/run/tz_vmm/image.bin var/run/tz_vmm/uImage
Next, i copy the image to the micro sd card.
On the u-boot shell:
ext2load mmc 0:1 0x71000000 uImage
bootm 0x71000000
OUTPUT:

and then errors described at the beginning.
I was looking in the code and dumping some output to find the problem,
at repos/os/src/server/tz_vmm/include/vm_base.h:
_load_kernel() function, at lines #52-53 the memcpy crashes.
the arguments being passed to him are: destination: 80008000 source:
f0001000, size: 3203072
what am i doing wrong ?
Thanks
Ofer
