I unfortunately don't have experience with git lfs.

 

I'm thinking about the subpath argument to SRC_URI git fetcher.

 

https://www.yoctoproject.org/docs/current/bitbake-user-manual/bitbake-user-manual.html#git-fetcher

Unfortunately, there are other files in the same directory that can’t be checked out. Looking at that documentation, I have added the “nocheckout=1” option to the git definition in SRC_URI which is stopping the initial pull.

When I try to add any git commands into a do_fetch_append() then it dumps a load of Python looking stuff on the screen that ends with:

  File "autogenerated", line 4
    git lfs checkout build/filename
               ^
SyntaxError: invalid syntax
