DebugBridge fails to connect

[jacopoabramo]

Greetings,

I tried using the DebugBridge class together with the debug bridge IP in my design but could not make it work. I documented the problem in this post. Does the original author of this class have some idea on what am I doing wrong?

• PYNQ version 3.0.1
• board PYNQ-ZU
• IP generated with Vivado 2023.1

Thanks in advance.

Best,

Jacopo

Hi,

looks like a simple bug to me:
The DebugBridge constructor checks if the description is of type ReprDict (this line) while other drivers, such as the DMA, check for ReprDict or dict (here).

I was able to work around this using:

from pynq.lib.debugbridge import DebugBridge
from pynqutils.runtime.repr_dict import ReprDict

bridge_desc = ReprDict(ol.ip_dict["debug_bridge_0"]) # ol is the Overlay
bridge = DebugBridge(bridge_desc)
bridge.start_xvc_server(bufferLen=4096, serverAddress="0.0.0.0", serverPort=2542, reconnect=True, verbose=True)

That's a good point @fpjentzsch. That check is not really necessary, although it can be fixed as you suggest.
Could you do a PR?
