使用RustSBI & U-Boot在QEMU中启动openEuler 23.09

本教程给出了使用RustSBI和U-Boot在QEMU中启动openEuler 23.09的基本流程。

本教程使用软件版本如下：

软件	版本
riscv64-linux-gnu-gcc	14.1.0
qemu-system-riscv64	9.0.1
RustSBI Prototyper	0.0.0
U-Boot	2024.04

准备RustSBI Prototyper， U-Boot ，openEuler 23.09

创建工作目录并进入该目录

$ mkdir workshop && cd workshop

Clone RustSBI Prototyper

$ git clone https://github.com/rustsbi/prototyper.git && cd prototyper && git checkout main && cd ..

Clone U-Boot

$ git clone https://github.com/u-boot/u-boot.git && cd u-boot && git checkout v2024.04 && cd ..

下载openEuler 23.09 Qemu磁盘镜像文件

下载链接：openEuler 23.09

 $ unzstd openEuler-23.09-V1-base-qemu-preview.qcow2.zst

• The password of user root is openEuler12#$.
• The password of the default user openeuler is openEuler12#$.

编译RustSBI Prototyper

进入prototyper目录

$ cd prototyper

编译RustSBI Prototyper

$ cargo prototyper

编译U-Boot SPL

进入U-Boot目录

$ cd u-boot

导出环境变量

$ export ARCH=riscv
$ export CROSS_COMPILE=riscv64-linux-gnu-
$ export OPENSBI=../prototyper/target/riscv64imac-unknown-none-elf/release/rustsbi-prototyper.bin 

生成.config文件,编译U-Boot

# To generate .config file out of board configuration file
$ make qemu-riscv64_spl_defconfig
$ ./scripts/config -e CMD_BTRFS -e FS_BTRFS
$ make olddefconfig
$ sed -i.bak 's/# CONFIG_USE_BOOTARGS is not set/CONFIG_USE_BOOTARGS=y\nCONFIG_BOOTARGS="root=\/dev\/vda1 rw console=ttyS0 swiotlb=1 loglevel=7 systemd.default_timeout_start_sec=600 selinux=0 highres=off earlycon"/' .config
$ make -j$(nproc)

使用RustSBI 原型系统和U-Boot启动openEuler 23.09

进入workshop目录

$ cd workshop

运行下面命令

$ qemu-system-riscv64 \
    -nographic -machine virt \
    -smp 4 -m 8G \
    -bios ./u-boot/spl/u-boot-spl  \
    -device loader,file=./u-boot/u-boot.itb,addr=0x80200000 \
    -drive file=openEuler-23.09-V1-base-qemu-preview.qcow2,format=qcow2,id=hd0 \
    -object rng-random,filename=/dev/urandom,id=rng0 \
    -device virtio-vga \
    -device virtio-rng-device,rng=rng0 \
    -device virtio-blk-device,drive=hd0 \
    -device virtio-net-device,netdev=usernet \
    -netdev user,id=usernet,hostfwd=tcp::12055-:22 \
