I tried to follow the following video creating a simple adder IP and accessing it in Python :
I get a userWarning: Users will not get parameters / registers information through TCL files. HWH file is recommended.
On the adder IP example after executing :
from pynq import Overlay
overlay = Overlay(‘/home/xilinx/pynq/overlays/adder/adder.bit’)
I added xadd_hw.h file in same location as the adder.bit and adder.tcl files. I did not change the name of the xadd_hw.h but still get the same warning as above !
