Ubuntu20.04下Yocto项目bitbake编译fetch错误求助

问题场景 #

在Ubuntu 20.04环境下构建NXP i.MX Yocto项目（版本L5.15.32-2.0.0，目标机imx8mn-ddr4-evk），执行bitbake imx-image-core时出现核心编译错误，关键报错为linux-imx仓库拉取失败，同时伴随gobject-introspection资源下载警告，完整错误日志如下：

解决步骤 #

1. 修复linux-imx仓库拉取失败问题 #

错误代码128说明Git无法正常访问目标仓库，按以下顺序排查：

• 手动测试仓库连通性：在终端执行命令，确认是否能直接克隆仓库：

  git clone --bare --mirror https://source.codeaurora.org/external/imx/linux-imx.git test-mirror
  

  如果克隆失败：
  • 检查网络是否能访问source.codeaurora.org（可通过ping或浏览器验证）
  • 若处于受限网络，配置Git代理：

    git config --global http.proxy http://your-proxy-addr:port
    git config --global https.proxy http://your-proxy-addr:port
    

    编译完成后可取消代理：

    git config --global --unset http.proxy
    git config --global --unset https.proxy
    

• 手动导入仓库镜像：如果无法通过Git拉取，将提前准备好的linux-imx分支镜像放入Yocto下载目录：
  1. 获取对应lf-5.15.y分支的仓库压缩包或镜像
  2. 将文件放入~/Desktop/imx-yocto-bsp/downloads/git2/，命名为source.codeaurora.org.external.imx.linux-imx.git
  3. 重新执行bitbake imx-image-core

2. 解决gobject-introspection下载警告 #

修改Yocto配置文件添加镜像源，加速资源下载：

• 打开conf/local.conf，添加GNOME国内镜像：

  PREMIRRORS_prepend = " \
  https://download.gnome.org/sources/ http://mirrors.ustc.edu.cn/gnome/sources/ \
  "
  

3. 清理缓存后重试 #

若之前的失败导致缓存异常，执行以下命令清理后重新编译：

bitbake -c cleanall linux-imx
bitbake imx-image-core

4. 消除多提供者警告（可选） #

针对日志中linux-firmware-bcm4359-pcie的多提供者提示，在conf/local.conf中添加指定提供者：

PREFERRED_RPROVIDER_linux-firmware-bcm4359-pcie = "firmware-nxp-wifi"

或根据需求选择linux-firmware。
