你好
我正在使用 NXP Yocto Rev. LF5.15.52_2.1.0 为 IMXQM 构建图像，但在为 nxp-demo-experience 配方执行获取任务时出错：
错误：解析 /home/wzg/8TB/Yocto/L5.15.52-2.1.0/sources/meta-nxp-demo-experience/recipes-nxp-demo-experience/nxp-demo-experience/nxp-demo- 时出现 ExpansionError experience_git.bb
追溯（最近调用最后一次）：
文件“/home/wzg/8TB/Yocto/L5.15.52-2.1.0/sources/poky/bitbake/lib/bb/fetch2/__init__.py”，第 1212 行，在 srcrev_internal_helper（ud=

==“AUTOINC”：

返回 rev

失败的变量依赖链是： SRCPV -> PV -> BP -> FILESPATH
错误：解析因错误而暂停，请参阅上面的错误消息
我认为根本案例是 nxp-demo-experience_git.bb 中的 SRCREV = "${AUTOREV}" ，
怎么办？
