linux5.10.110内核编译完之后，将新内核文件复制到目标系统中。

1.从开发机下复制下面的文件到firmware文件夹：

cp arch/arm/boot/dts/*.dtb ../firmware/
cp arch/arm/boot/dts/overlays/*.dtb* ../firmware/overlays/
cp arch/arm/boot/dts/overlays/README ../firmware/overlays/
cp arch/arm/boot/zImage ../firmware/kernal7l.img
cp -r /lib/modules/5.10.110-v7l+ ../firmware

2.将firmware文件夹下的文件复制到目标板文件夹：

sudo cp firmware/*.dtb /boot/
sudo cp firmware/overlays/*.dtb* /boot/overlays/
sudo cp firmware/dts/overlays/README /boot/overlays/
sudo cp firmware/kernal7l.img /boot/kernal7l.img
sudo cp firmware/5.10.110-v7l+ /lib/modules/
