Hi Jonathan,

Thanks for the response. I tried as you suggested and found the same result
as before. I haven't yet modified the UHD code, except for doing a
"submodule init" and "submodule update". Do you have any other suggestions?

git status
HEAD detached at release_003_010_003_000
Changes not staged for commit:
  (use "git add <file>..." to update what will be committed)
  (use "git checkout -- <file>..." to discard changes in working directory)
  (commit or discard the untracked or modified content in submodules)

    modified:   ../../fpga-src (modified content)

no changes added to commit (use "git add" and/or "git commit -a")
