subdirs-y += mcp55 This one would be here, except you mean another line...
Yes that line. When it was commented out I got the same error you're getting, but when it isn't I don't get that error.
Do you see the mcp55 files being built?
Oh yeah, that was a RIGHT hint!
Great.
But on a different level of the tree.
Oops. I'm glad you found it anyway. I should have looked more closely.
Thanks, Myles
