I may have a problem with one of my PicoZed SDRs. It seems the Ethernet PHY has an issue. Linux boots the PHY without a problem and can read/write from/to the PHY, but anything external doesn't see any activity. For example, basic network functions such as ping won't work.
We tried multiple carrier cards, and the problem appears to follow the SOM. Using a new SOM fixes the problem.
Thank you for your time.
