Yocto：失败扩展变量kernel_localversion
从本地工作区构建内核时，我面临着以下错误（DevTool修改Virtual/kernel）。如果我没有创建工作空间，那么我不会看到任何错误。
ERROR: ExpansionError during parsing /home/aws-fsp-build/rax-workspace/yocto/meta-ti/recipes-kernel/linux/linux-ti-staging-rt_5.10.bb
Traceback (most recent call last):
File "Var <KERNEL_LOCALVERSION>", line 1, in <module>
bb.data_smart.ExpansionError: Failure expanding variable KERNEL_LOCALVERSION, expression was -g${@d.getVar('SRCPV', True).split('+')[1]} which triggered exception IndexError: list index out of range
您能帮我解决这个问题吗？自从我从事与内核相关的更改以来，我需要拥有工作空间。我正在使用dunfell meta-ti的分支。

I am facing below error while building kernel from local workspace(created by devtool modify virtual/kernel). If I do not have workspace created then I don't see any error.

Can you help me on resolving this? I need to have workspace since I am working on kernel related changes. I am using dunfell branch of meta-ti.

似乎在移至工作空间后，SRCPV变量更改格式化，这会导致解析失败。尝试将类似的内容添加到build/workspace/appends/linux-ti阶段rt_5.4.4.bbappend文件：
It seems like after moving to the workspace, the SRCPV variable changes formatting, which leads to parsing failure. Try to add something like this to the build/workspace/appends/linux-ti-staging-rt_5.4.bbappend file:
