Running PYNQ 3.0.1 on the RFSoC 4x2 device with the unmodified base overlay.
I bought a loopback module to run the CMAC_Intro notebook.
The loopback module is below:
Amphenol SF-100GLB0W00-0DB QSFP28 Loopback Adapter Module, 100 Gb Ethernet, 0 dB Insertion Loss, 0W Power
When running the CMAC_Intro notebook (notebooks/base/board/CMAC_Intro.ipynb) I get a “Receive Channel not aligned error.” when running the blocks
base.cmac.internal_loopback = 0
base.cmac.start()
The error is shown below:
RuntimeError Traceback (most recent call last)
Input In [5], in <cell line: 1>()
----> 1 base.cmac.start()
File /usr/local/share/pynq-venv/lib/python3.10/site-packages/pynq/lib/cmac.py:598, in CMAC.start(self)
596 self.register_map.conf_tx = 1
597 return
→ 598 raise RuntimeError(“Receive channel not aligned”)
RuntimeError: Receive channel not aligned
Any ideas on what could be the problem? Thanks!
