Dear, everyone.

I try to full system simulation for ARM ISA.
So, I downloaded the pre-compiled kernels and disk images
(aarch-system-20170616.tar.xz) from the repository (

There are several dtb files like below.

However, not for 8 or 16 cpus.
If I want to experiment 16-cpu configuration, I should modify the dtb file?

If I should modify the dtb file, how I can do that?
I found the documentations to build a kernel or to make a disk image.

But, I couldn't find any documentation to modify the dtb file.
Is there any documentation for the dtb file?

Best regards,
Haeyoon Cho.
