vexpress ca9 linux kernel qemu环境搭建记录

Posted 2020-10-16

 

kernel

下载kernel ,解压缩后编译

make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- O=../tl distclean
make vexpress_defconfig ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- O=../tl
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- -j8 O=../tl

 

rootfs

下载busybox代码，

make ARCH=arm menuconfig  配置下编译器，配置成静态busybox.

make 

make install

安装到_intall目录下面

 

 

制作rootfs 镜像：

sudo mkdir tmpfs 
sudo mount -t ext3 a9rootfs.ext3 tmpfs/ -o loop 
cp -r busybox/_install/* tmpfs/ 
从https://github.com/mahadevvinay/Embedded_Linux_Files.git下载fstab inittab rcs文件
cd tmpfs
mkdir -p etc etc/init.d mkdir proc sys home dev tmp root var mnt
cd ..
cp fstab tmpfs/etc
cp inittab tmpfs/etc
cp rcS tmpfs/etc/init.d
sudo chmod a+x tmpfs/etc/init.d/rcS
sudo umount tmpfs

 

运行

qemu-system-arm -M vexpress-a9 -m 512M -nographic -append "root=/dev/mmcblk0 console=ttyAMA0" -kernel ../tl/arch/arm/boot/zImage -dtb ../tl/arch/arm/boot/dts/vexpress-v2p-ca9.dtb -sd ../a9rootfs.ext3
