imx8qxpmek在yocto中使用sstate出现错误怎么解决？

我正在尝试使用 sstate 来提高构建速度并 减少所需的磁盘空间。
首先，创建一个干净的构建。
DISTRO=fsl-imx-wayland MACHINE=imx8qxpc0mek source imx-setup-release.sh -b build然后编辑 build/conf/local.conf
SSTATE_DIR ?="/share/yocto-sstate/"并建立，一切都很好。
bitbake imx-image-multimedia但是另一个构建尝试使用相同的 sstate 出现错误。
DISTRO=fsl-imx-wayland MACHINE=imx8qxpc0mek source imx-setup-release.sh -b build2

# build2/conf/local.conf
SSTATE_DIR ?="/share/yocto-sstate/"

#Then build
bitbake imx-image-multimedia并收到错误
