Hey all, apologies for this post if it doesn’t meet rules, I’m new to the PYNQ world but have had difficulty trying to compile the base Pynq-Z1 overlays in my environment. I’ve run the makefile (using the command `make all`) and directly from Vivado 2020.2 using the TCL scripts (`source ./build_ip.tcl`). I made sure to check the Releases page for PYNQ 2.7 to make sure I had the correct version of Vivado, and made sure that Ubuntu 20.04 was listed as supported. What am I doing incorrectly, or what do I not have configured correctly?

My error message output (following a successful compile of color\_convert I believe) is the following:

```auto

Any help would be greatly appreciated.

I corrected the issue: After doing a bit more digging, I found that this was a bug in Vivado that was patched by Xilinx. Apologies for the obvious question, but for anyone else who could be dealing with the same issue, see here:
