Hi Ciro, I am finally able to boot more than 32 cores. The problem was in the boot file I was using, which was quite old. I compiled the boot file under gem5/system/arm/aarch64_bootloader and that fixed the problem.
Thank you.

I also tried to use the auto generated dtb, but that didn't help either.

The most important difference I see is that I'm not passing a DTB, which enables automatic DTB generation, which is more likely to be correct than the manually created one.
