我有一个STM32MP1 SBC，我正在与yocto项目一起使用它。STM提供了Cubemx工具，用于生成设备树等。我已经按照本文中的说明进行了操作，但无法编译设备树。。https://wiki.st.com/stm32mpu/wiki/How_to_compile_the_device_tree_with_the_Distribution_Package
我的layer.conf是这样的。。
# We have a conf and classes directory, add to BBPATH
BBPATH .= ":${LAYERDIR}"

我知道这是一篇旧帖子，但我也遇到了同样的问题，这个解决方案可以帮助未来的用户：
首先，您需要在如何在STM32CubeIDE中管理OpenSTLinux项目(您需要在linux机器上(
然后简单地从STM32CubeIDE运行CA7项目或手动将生成的.dtb复制到"/boot/stm32mp157a-dk1.dtb"；(设置正确的卡名(
