You don't actually have an external branch, because you made the right
choice to use git to manage your BSP :P So you don't need this.

This is all good, I run with this all day every day .. so far so good.

Aha. This is the problem, if you've decided to create a local repo,
and a BSP branch, you don't need these files outside of the tree. But
I'm betting these were created by the BSP tool .. hence the confusion
as two methods are being mixed.

If you stop using the local repository, and just use the BSP tool that
should at least clarify the error messages and I can help more after
that.

Cheers,
