ValueError: embedded null byte while implementing DPR on ZCU216

[H.W]

Thank you for the reply.

1. My inspiration is actually from this link:
   PYNQ 2.7 DFX Partial Reconfiguration under Vivado 2020.2

He used the same PYNQ version and same Partial Reconfiguration Implementation as I did.
(However the vivado version and board are different)

2. In you suggestions, which states:
   " In the following example, let us assume there is a hierarchical block called block_0 in the design."

I do have a hierarchy called “pr_sec” for the DPR, (check in the image above.) but I can’t find it in the ip_dict in PYNQ:

AttributeError: Could not find IP or hierarchy pr_sec in overlay

Is there anything I missed or doing wrong?

BR,
H.W
