我这里 raspi4b 跑不起来。但是 raspi3b 可以。

wget <https://downloads.raspberrypi.com/raspios_arm64/images/raspios_arm64-2025-05-07/2025-05-06-raspios-bookworm-arm64.img.xz>

# mount it to loop
sudo losetup -fP 2025-05-06-raspios-bookworm-arm64.img 
mkdir tmp dtbs img
# maybe you are loopx
sudo mount /dev/loop0p1 tmp/
cp tmp/*.dtb dtbs
cp tmp/kernel* img
sudo losetup -d /dev/loop0

# resize img, -sd taget must be 2^x

	-device usb-kbd -device usb-tablet \\
	-device usb-net,netdev=net0 \\
	-netdev user,id=net0,hostfwd=tcp::4444-:22 -vnc :0

注意 -vnc :0 参数， 使用vnc进行控制， 请在 vnc client (例如 vnc viewer) 输入 localhost:5900 连接输出

这是设备树和内核文件
