origin
With the popularity of aarch64 on mobile phones and servers, it is more and more necessary for us to learn the knowledge of aarch64. But at present, there is no good development board of aarch64 on the market. Before that, I bought a NanoPC-T3. The SoC used is Samsung's 6818, which is cortex-a538 core architecture. But all the information provided by the merchant is 32-bit (armv8 is compatible with aarch32 and aarch64). They said that Samsung did not give 64-bit BSP data, so they had to wait for Samsung to solve it. I was disappointed to see that someone on the Internet used Qemu simulator to build the running environment of aarch64, so I saw the dawn, so I searched the information from the Internet to pave the way for future generations.
The following software packages are available Here Download.
Functions
Simulate a cortex-a53 dual-core or single-core environment and communicate with Host to share some files. For simplicity, the root file system uses ramdisk format.

1. Compiling Qemu Simulator
First to Qemu official website Download the latest simulator, I'm going to download Qemu-2.8.0 Or you can download it Other versions
1 tar -xf qemu-2.8.0.tar.xz 2 cd qemu-2.8.0/ 3 mkdir build 4 cd build/ 5 # We need to install this package because we have enabled it.--enable-virtfs， otherwise configure Sometimes it fails. 6 sudo apt-get install libcap-dev 7 ../configure --target-list=arm-softmmu,i386-softmmu,x86_64-softmmu,aarch64-linux-user,arm-linux-user,i386-linux-user,x86_64-linux-user,aarch64-softmmu --audio-drv-list=alsa --enable-virtfs 8 make -j8 9 sudo make install
Then you can use the qemu-system-aarch64 tool that we will use next.
2. Download Tool Chain
Log on to this website: http://www.veryarm.com/aarch64-linux-gnu-gcc
There are some points for attention:
Aarch64-linux-gnu-gcc is an ARM cross-compiling tool developed by Linaro based on GCC. It can be used to cross-compile bare-machine programs, u-boot, Linux kernel, filesystem and App applications in ARMv8 64-bit targets. The aarch64-linux-gnu-gcc cross-compiler must be installed on the 64 host in order to compile the target code.
We use the latest Linux decompression here:
3. Download and compile the latest Linux kernel
Sign in https://www.kernel.org/， Download the latest version of Linux. Linux-4.10.
Here is the command to compile the following kernel:
1 #!/bin/bash 2 cross_compile=/home/pengdonglin/src/qemu/aarch64/gcc-linaro-aarch64-linux-gnu-4.9-2014.07_linux/bin/aarch64-linux-gnu- 3 make CROSS_COMPILE=$cross_compile ARCH=arm64 O=./out_aarch64 defconfig 4 make CROSS_COMPILE=$cross_compile ARCH=arm64 O=./out_aarch64 menuconfig 5 make CROSS_COMPILE=$cross_compile ARCH=arm64 O=./out_aarch64 Image -j4
Since ramdisk startup mode is used below, it needs to be supported in the kernel configuration:
1 General setup ---> 2 ----> [*] Initial RAM filesystem and RAM disk (initramfs/initrd) support 3 4 Device Drivers ---> 5 [*] Block devices ---> 6 <*> RAM block device support 7 (65536) Default RAM disk size (kbytes)
The default size we set for ramdisk here is 64MB, which is not smaller than the size of ramdisk.img we actually generated later.
In addition, because we also need to support NFS hanging and sharing files with Host through 9p, these also need to be configured in the kernel. (The default configuration is already supported)
About the 9p mode of Qemu to realize directory sharing with Host, you can refer to: qemu uses 9p to support shared directories in host and guest
So there's the kernel mirror Image we're going to use next.
4. Making Root File System
Sign in https://busybox.net/downloads/ Download the version of busybox to use. Here I'm going to download busybox-1.24.2
There are not many settings to be set up:
Execute make menuconfig to configure the following items:
1 Build Options ---> 2 3 [*] Build BusyBox as a static binary (no shared libs) 4 5 (/home/pengdonglin/src/qemu/aarch64/gcc-linaro-aarch64-linux-gnu-4.9-2014.07_linux/bin/aarch64-linux-gnu-) Cross Compiler prefix
Then execute the make & make install command
Now I make a ramdisk for startup, and I write a script for this process, as follows:
1 #!/bin/bash 2 sudo rm -rf rootfs 3 sudo rm -rf tmpfs 4 sudo rm -rf ramdisk* 5 sudo mkdir rootfs 6 sudo cp ../busybox-1.24.2/_install/* rootfs/ -raf 7 sudo mkdir -p rootfs/proc/ 8 sudo mkdir -p rootfs/sys/ 9 sudo mkdir -p rootfs/tmp/ 10 sudo mkdir -p rootfs/root/ 11 sudo mkdir -p rootfs/var/ 12 sudo mkdir -p rootfs/mnt/ 13 sudo cp etc rootfs/ -arf 14 sudo mkdir -p rootfs/lib 15 sudo cp -arf ../gcc-linaro-aarch64-linux-gnu-4.9-2014.07_linux/aarch64-linux-gnu/libc/lib/aarch64-linux-gnu/* rootfs/lib/ 16 sudo rm rootfs/lib/*.a 17 sudo ../gcc-linaro-aarch64-linux-gnu-4.9-2014.07_linux/bin/aarch64-linux-gnu-strip rootfs/lib/* 18 sudo mkdir -p rootfs/dev/ 19 sudo mknod rootfs/dev/tty1 c 4 1 20 sudo mknod rootfs/dev/tty2 c 4 2 21 sudo mknod rootfs/dev/tty3 c 4 3 22 sudo mknod rootfs/dev/tty4 c 4 4 23 sudo mknod rootfs/dev/console c 5 1 24 sudo mknod rootfs/dev/null c 1 3 25 sudo dd if=/dev/zero of=ramdisk bs=1M count=16 26 sudo mkfs.ext4 -F ramdisk 27 sudo mkdir -p tmpfs 28 sudo mount -t ext4 ramdisk ./tmpfs/ -o loop 29 sudo cp -raf rootfs/* tmpfs/ 30 sudo umount tmpfs 31 sudo gzip --best -c ramdisk > ramdisk.gz 32 sudo mkimage -n "ramdisk" -A arm -O linux -T ramdisk -C gzip -d ramdisk.gz ramdisk.img

5. Qemu Support Network
Please refer to the blog:
Simulate vexpress-a9 with qemu--Configure the network function of qemu
Simulating vexpress-a9(3) with Qemu--Implementing booting Linux kernel with u-boot
6, test
Method of sharing directories:
1 sudo qemu-system-aarch64 \ 2 -M virt \ 3 -cpu cortex-a53 \ 4 -smp 2 \ 5 -m 4096M \ 6 -kernel ./linux-4.10/out_aarch64/arch/arm64/boot/Image \ 7 -nographic \ 8 -append "root=/dev/ram0 rw rootfstype=ext4 console=ttyAMA0 init=/linuxrc ignore_loglevel" \ 9 -initrd ./rootfs/ramdisk.img \ 10 -fsdev local,security_model=passthrough,id=fsdev0,path=/nfsroot \ 11 -device virtio-9p-pci,id=fs0,fsdev=fsdev0,mount_tag=hostshare
Support network startup:
1 sudo qemu-system-aarch64 \ 2 -M virt \ 3 -cpu cortex-a53 \ 4 -smp 2 \ 5 -m 4096M \ 6 -kernel ./linux-4.10/out_aarch64/arch/arm64/boot/Image \ 7 -nographic \ 8 -append "root=/dev/ram0 rw rootfstype=ext4 console=ttyAMA0 init=/linuxrc ignore_loglevel" \ 9 -initrd ./rootfs/ramdisk.img \ 10 -net nic,vlan=0 -net tap,vlan=0,ifname=tap0
Of course, the above two sides can also be combined:
1 sudo qemu-system-aarch64 \ 2 -M virt \ 3 -cpu cortex-a53 \ 4 -smp 2 \ 5 -m 4096M \ 6 -kernel ./linux-4.10/out_aarch64/arch/arm64/boot/Image \ 7 -nographic \ 8 -append "root=/dev/ram0 rw rootfstype=ext4 console=ttyAMA0 init=/linuxrc ignore_loglevel" \ 9 -initrd ./rootfs/ramdisk.img \ 10 -net nic,vlan=0 -net tap,vlan=0,ifname=tap0 \ 11 -fsdev local,security_model=passthrough,id=fsdev0,path=/nfsroot \ 12 -device virtio-9p-pci,id=fs0,fsdev=fsdev0,mount_tag=hostshare
We need to specify a shared directory on Host, such as / nfsroot, and configure it in / etc/export if mounted with nfs.
nfs mount:
mount -t nfs -o nolock 172.16.14.203:/nfsroot /mnt
9p mount:
mount -t 9p -o trans=virtio,version=9p2000.L hostshare /mnt2
This makes it possible to share files with Host. It is recommended to use 9p mode, which is more stable.
