编译和运行qemu-uboot-arm64单板的Armbian系统

这篇文章ARM虚拟机安装OMV-CSDN博客遗留一个启动qemu-uboot-arm64单板Armbian镜像的问题，使用官方下载的镜像，会报错：

说明：上面的启动命令，参考config/boards/qemu-uboot-arm64.csc：

qemu-system-aarch64 -smp 8 -m 8G -machine virt -nographic -cpu cortex-a72 -bios Armbian_24.5.0-trunk.558_Qemu-uboot-arm64_noble_current_6.6.30_minimal.u-boot.bin -nic user,model=virtio-net-pci -drive if=none,media=disk,id=drive0,file=Armbian_24.5.0-trunk.558_Qemu-uboot-arm64_noble_current_6.6.30_minimal.img.qcow2,discard=unmap,detect-zeroes=unmap -device virtio-blk-pci,drive=drive0,bootindex=0

在网上找了好几轮，没有找到启动的方法，但是根据这篇文章Running self-build image on QEMU arm64 - Beginners - Armbian Community Forums

作者编译和启动qemu-uboot-arm64 Armbian镜像是没有问题的，因此考虑自己编译qemu-uboot-arm64镜像。

参考官网文档下载Armbian编译项目。

因为Armbian编译有系统要求，我使用了VirtualBox安装Ubuntu 22.04服务器虚拟机来编译（在Ubuntu 24.04系统上编译遇到Docker的问题无法编译，后续再研究）。

apt-get -y install git
git clone --depth=1 --branch=main https://github.com/armbian/build
cd build
./compile.sh

按照上面的方式，选择uefi-arm64单板编译，可以成功编译出镜像并运行（运行uefi-arm64参考开头提到的OMV安装的文章）。

但是在编译qemu-uboot-arm64单板的时候遇到问题：u-boot的Makefile（https://raw.githubusercontent.com/u-boot/u-boot/4459ed60cb1e0562bc5b40405e2b4b9bbf766d57/Makefile）由于网络的原因一直无法下载成功。

./compile.sh BOARD=qemu-uboot-arm64 BRANCH=current RELEASE=bookworm

解决办法：

编译命令增加UBOOT_MIRROR=gitee，将u-boot改为从gitee下载：

./compile.sh BOARD=qemu-uboot-arm64 BRANCH=current RELEASE=bookworm UBOOT_MIRROR=gitee

但实际上执行这个命令，u-boot还是从github下载，而不是预期的gitee。

一番跟踪代码之后，发现是UBOOT_MIRROR没有生效，再修改config/sources/families/include/uefi_common.inc文件，把BOOTSOURCE改为"${MAINLINE_UBOOT_SOURCE}"：

[192.168.2.108] alpha@mascot.x ~/workspace/armbian/build $ git diff
diff --git a/config/sources/families/include/uefi_common.inc b/config/sources/families/include/uefi_common.inc

        declare -g BOOTCONFIG="${QEMU_UBOOT_BOOTCONFIG}"
        add_packages_to_image spice-vdagent qemu-guest-agent # Nice-to-have packages for running under qemu

再次执行上面的编译命令（或者下面更完整的编译命令），终于u-boot可以从gitee下载，可以顺利编译出qemu-uboot-arm64单板镜像（中途有出错，重新编译就可以了）：

./compile.sh build BOARD=qemu-uboot-arm64 BRANCH=current BUILD_DESKTOP=no BUILD_MINIMAL=no KERNEL_CONFIGURE=no RELEASE=bookworm UBOOT_MIRROR=gitee

并且可以运行：
