STM32MP15-Disco平台BitBake构建b2qt-embedded-qt6-image失败求助

环境与背景 #

• 使用Boot2Qt 6.7.3清单，针对STM32MP15-Disco平台（MACHINE=stm32mp15-disco）
• 依赖meta-qt6层及匹配nanbield版本的meta-st层
• 自定义Qt应用配方（基于Qt 6.7.3）可单独通过BitBake成功构建

问题现象 #

将自定义配方加入local.conf后，执行bitbake b2qt-embedded-qt6-image时出现编译失败，错误指向qtwebengine组件及boot2qt-demolauncher的unpack步骤：

| cd /home/vboxuser/yocto/build-stm32mp15-disco/tmp/work/cortexa7t2hf-neon-vfpv4-poky-linux-gnueabi/qtwebengine/6.7.3/build/src/core && /home/vboxuser/yocto/build-stm32mp15-disco/tmp/work/cortexa7t2hf-neon-vfpv4-poky-linux-gnueabi/qtwebengine/6.7.3/recipe-sysroot-native/usr/bin/ninja -C /home/vboxuser/yocto/build-stm32mp15-disco/tmp/work/cortexa7t2hf-neon-vfpv4-poky-linux-gnueabi/qtwebengine/6.7.3/build/src/core/Release/arm QtWebEngineCore

核心疑问：自定义应用配方并未依赖QtWebEngine，但构建镜像时却触发该组件的编译失败，不清楚原因及解决方向，甚至考虑是否需要改用ST官方清单重新搭建环境。
