Hi, I have a pynq-Z2 board and am trying to experiment with a BRAM in a custom overlay.
I have made this basic overlay:
since I am using the free version of vivado I am limited in choices for the BRAM, most are at their default resulting in the summary:
Now when I validate this design I get the error
User configuration exceeds BRAM count in the selected device
However according to the summary there are only 8 36k BRAMs used, that should fit on the pynq-Z2 since it uses a zynq 7000. Also there are projects on the internet using a BRAM generator on Z2, like here. I am puzzled by this, anybody got any ideas on why this happens?
