Arch Linux运行树莓派系统（2022年）
Arch Linux运行树莓派系统（2022年）
需要安装QEMU及其相应的aarch64虚拟包，具体安装方法已经忘了，网上应该能搜得到（比如Arch wiki），本篇主要内容是树莓派系统镜像的提取
参考国外的脚本（注意，稍微做了一丢丢修改，适应QEMU7.0的配置），把树莓派的btd和kernel提取出来，启动镜像
pwn@host$ mkdir aarch64_tests && cd aarch64_tests
pwn@host$ wget https://downloads.raspberrypi.org/raspios_arm64/images/raspios_arm64-2022-01-28/2022-01-28-raspios-bullseye-arm64.zip | busybox unzip -
pwn@host$ sudo mkdir /mnt/raspbian
pwn@host$ fdisk -l 2022-01-28-raspios-bullseye-arm64.img
# Check the 'Start' value of 2022-01-28-raspios-bullseye-arm64.img1 and multiply by 512 That will be your **N**
pwn@host$ sudo mount -v -o offset=N -t vfat 2022-01-28-raspios-bullseye-arm64.img /mnt/raspbian
pwn@host$ cp /mnt/raspbian/kernel8.img $(pwd)
pwn@host$ cp /mnt/raspbian/bcm2710-rpi-3-b-plus.dtb $(pwd)
pwn@host$ sudo umount /mnt/raspbian
# Ensure you have QEMU 7.0 installed at this point
pwn@host$ qemu-img resize 2022-01-28-raspios-bullseye-arm64.img 8G
pwn@host$ qemu-system-aarch64 -m 1024 -M raspi3b -kernel kernel8.img -dtb bcm2710-rpi-3-b-plus.dtb -sd 2022-01-28-raspios-bullseye-arm64.img -append "console=ttyAMA0 root=/dev/mmcblk0p2 rw rootwait rootfstype=ext4" -nographic -device usb-net,netdev=net0 -netdev user,id=net0,hostfwd=tcp::5555-:22
# At this point raspbian should boot on the terminal
raspberrypi login: pi
Password: raspberry
pi@raspberry:~$ sudo service ssh start
pi@raspberry:~$ sudo update-rc.d ssh enable
# At this point we should have been inside the QEMU RaspbianOS instance with ssh
pwn@host$ ssh [email protected] -p 5555
pi@raspberry:~$ sudo apt update && sudo apt install neovim nasm -y && bash -c "$(curl -fsSL http://gef.blah.cat/sh)"
由于没用libvirtd管理，所以只能通过脚本启动
//start.sh
qemu-system-aarch64 -m 1024 -M raspi3b -smp 4 -kernel kernel8.img -dtb bcm2710-rpi-3-b-plus.dtb -sd 2022-01-28-raspios-bullseye-arm64.img -append "console=ttyAMA0 root=/dev/mmcblk0p2 rw rootwait rootfstype=ext4" -nographic -device usb-net,netdev=net0 -netdev user,id=net0,hostfwd=tcp::5555-:22

结语
感觉体验并不流畅，启动缓慢，一方面可能是qemu的网卡没配置好，网速时好时坏，另外有可能是用了dektop版本的问题，一堆桌面应用去抢1GB内存肯定不够用。平时的话qemu-user应该够我做Arm64实验了，用不上这个。
tips:后面换了lite版本，跑起来相对流畅，至少能顺利把实验做完了。
总之，不推荐使用这种方式开发树莓派
现在先写一下，没准以后能用得上
