Hello, I am using genode 18.05 and I am trying the TZ_VMM demo on imx53-qsb board. I encountered problem when the system is booting. The error like this:

And my steps are:
- get linux image:
git clone https://github.com/skalk/linux.git git checkout imx53-tz cross_compile and get uImage
2.compile genode: ./tool/create_builddir hw_imx53_qsb_tz add RUN_OPT = --include boot_dir/hw --include image/uboot copy uImage to bin/linux
Here lies the problem, you cannot boot an uImage with our VMM. You should leave away the u-boot image header by copying it like this:
dd if=<lx_build_dir>/arch/arm/boot/uImage of=bin/linux bs=64 skip=1
Regards Stefan
comment out "exec >& /dev/null wget -O bin/linux.md5 $linux_uri.md5" comment out "exec md5sum -c linux.md5" make run/tz_vmm and get uImage
3.get u-boot git clone https://github.com/skalk/u-boot/tree/imx53_loco cross compile and get u-boot.imx
4.Booting by ext2load and bootm command.
Can anyone help me fix this problem?
