Are you sure that CONFIG_DTB_FILE was exported correctly?
Something as simple as that, could be the cause of the issue.

In my build script I have:

CONFIG_DTB_FILE=/path/to/vexpress-v2p-ca15-tc1.dtb make -C xen XEN_TARGET_ARCH=arm32 debug=y CROSS_COMPILE=/path/to/gcc-4.6.0-nolibc/arm-unknown-linux-gnueabi/bin/arm-unknown-linux-gnueabi-

Hi Stefano,



I have done almost the same thing but with toolchain version 4.6.3. The dtb file is being recognized during compiling xen as is evident from the output below. But still is not being recognized by the Fast Model and it shows the same error.

Could you please post the Fast Model command line that you are using?

Hi Stefano,

This is the FAST Model command I am using.

model_shell /path/to/FastModelsPortfolio_8.0/examples/RTSM_VE/Build_Cortex-A15x1/Linux-Release-GCC-4.4/cadi_system_Linux-Release-GCC-4.4.so /path/to/xen-unstable.git-xen-arm-4.3-3/xen/xen -C motherboard.flashloader0.fname=/path/to/boot/zImage

Unfortunately I cannot see anything wrong with your command line or
with the way you build Xen.
I tried to repeat you steps but it works for me, certainly pass the "No
valid device tree" point.
