Hi Cathal,

Thank you for the reply. I built the overlay in vivdao completely (to bitstream) and exported the bd tcl file manually using vivado. I managed to get the build back up and running by modding the TCL file in two places. I’ve attached it and commented my edits with # RV. It found the HLS ip no problome, but couldn’t find the non-HLS ip even though it came up fine in vivado’s IP library.

Does that make file build the needed files and place them in the boards/boardname/base directory? Or does it just build the boards/boardname/base/base vivdao project directory?
