Hi, i am looking for a base overlay for the ZCU111 board. I haven’t found anything similar, does it exist? It is because I want to do the same thing that was already asked here and it seems that there was no answer.

> I used RFSoC4x2 board before, and I’m going to use ZCU111 board. For PYNQ image, 2.7 version was used in RFSoC4x2, and 3.0.1 version is installed separately in ZCU111. Previously, the base.bit of RFSoC4x2 was used to generate signals in the same manner as in the picture below Through the above method, we were able to generate the desired frequency sine wave with DAC. However, with ZCU111, the overlay base is gone, and only the QPSK example remains. Therefore, I wonder if there is a…

I have a schedule, so my answer is late.
I progressing this project currently but as I know ‘base’ overlay doesn’t exist for ZCU111.
So I trying to ‘rfsoc\_radio’ and ‘rfsoc\_qpsk’ overlay in ZCU111.
This overlay dowanload method and example exist in ‘RFSOC\_SDR book’
But these overlays make based on arbitrarily made ‘dashboard’ in python.
So if you want to do a project based on this, I recommand analyze these overlays or make new overlay.
Additionally, if it is the same project, the ‘base’ overlay is considered unavailable. If necessary, you can check the overlay in Vivado.
