Hi Kranthi,
can you send me your resulting uImage (var/run/log/uImage) after a fresh built without NR_OF_CPUS changes to me personally so that I can test it on our board using my boot procedure?

Hello Stefan,
I've cloned the genode repository freshly as you have suggested. I've followed the following steps for building the uImage:
- Created a build directory by using /tool/create_builddir wand_quad
- Included "RUN_OPT += --include image/uboot in [1]
- Changed RAM0_SIZE = 0x80000000 to RAM0_SIZE = 0x40000000
- Run "make run/log" from the build directory [2]
When I haven't changed NR_OF_CPUS, it is hanging at "Starting kernel ..." itself. When I've changed NR_OF_CPUS to 1, I'm getting the following output:

We are unable to detect what the problem is. Am I missing something in the build process itself?
Thanks, Kranthi

Please, do not test the release version 17.02, but the _current_ master branch, e.g., by cloning the git repository: git@...116...:genodelabs/genode.git just to ensure whether this works for you. I've used this version successfully with all 4 cores enabled on the same board.
