Hi, I would like to debug a Qemu guest linux kernel under Foundationv8 model and I tried the following setup:
1. Foundationv8 model started with --network=nat and --network-nat-ports=1234=1234 options 2. In Foundationv8 model I started qemu-system-aarch64 with the command line: ./qemu-system-aarch64 -M virt -cpu host -kernel Image -serial stdio -display none -enable-kvm -gdb tcp::1234 -S 3. I start debugging the guest kernel with aarch64-linux-gnu-gdb vmlinux and with target remote:1234 command. However when I set any breakpoint I will get error message: "Cannot insert breakpoint 1. Error accessing memory address 0xffffffc000636498: Unknown error -1" In addition stepi or any other run related command does not work. Any ideas to fix this? -Jani
