Hi Jani, The video is about aarch64 (not 32-bit arm). For your original issue, I think you need armv8 MMU support (which is not merged yet), so qemu can not handle guest virtual address like 0xffffffc000636498. I just tried Peter's branch, using aarch64-qemu + aarch64-gdb to cross-debug arm64-kernel is working here. -- But, because aarch64 timer is not implemented in the current qemu, thus I can not get arm64-kernel scheduler working. Peter's branch is here: git://git.linaro.org/people/pmaydell/qemu-arm.git branch: a64-system Command I am using: 1) in one terminal: ./aarch64-softmmu/qemu-system-aarch64 -kernel ../../kernel/arch/arm64/boot/Image -machine virt -cpu cortex-a57 -s -S 2) in another terminal aarch64-linux-gnu-gdb ../../kernel/vmlinux target remote tcp::1234 b start_kernel On 02/27/2014 11:35 PM, Jani Kokkonen
