Dear qemu guys,
I've met with a strange problem when using qemu as simulator for arm64.
I tried to start qemu with the command below:
------
sudo qemu-system-aarch64 -machine virt -cpu cortex-a72 -smp 2 -m 2048 -kernel Image -append "console=ttyAMA0 root=/dev/vda" -nographic -drive file=ramdisk.img -drive file=disk.img -nic tap,model=e1000,script=/etc/qemu-ifup
------
The file:Image is the kernel bin of linux kernel which compiled with default config.
While I tried with linux kernel-5.15, then the simulator can be started properly.
For the kernel 6.3.8; kernel-5.10.130, the result is OK as well
But there's no output info after the command executed if the kernel before 4.19 is used.
Is there any problem when early linux kernel (before 4.19) is used for qemu tools ?
Thank you so much.
BestRegards,
Rex
