Error when loading overlay with AXI to APB bridge

Support
1

Dear all,

We wrote an overlay (PYNQ 2022.1), which contains the AXI4 to APB bridge. When loading the overlay, we get the error message:

UnexpectedPortTypeError: Expected cpu:apb_io_bridge_wrapper_0[block]:APB_IN[port] to be SubordinatePort when assigning base address

Other custom overlays work without problems. We also changed the name of the port from APB_IN to APB_S, but the error remains the same.

The address map in Vivado does not show any problems, all the addresses are unique.

Thanks a lot!
Best,
Yves

you can try uninstall pynqmetadata, git clone GitHub - Xilinx/PYNQ-Metadata: PYNQ-Metadata provides an abstract description of reconfigurable system designs. and install pynqmetadata, this works for me.
make sure Bugfix for over protective address mapping by STFleming · Pull Request #18 · Xilinx/PYNQ-Metadata · GitHub is in your branch, right now it’s on main branch, not on v0.1.7
