Hi Rob,
Thanks for this useful information.
According to Michael it should be fixed mid/late July 2021, so pretty
soon. Meanwhile I can only switch back to X310 probably, and see if it
works there.
Let's hope it would be fixed soon.
BR,

Hi Vladica,
From the 'changelog', it appears that N321 support began with release
3.14. But, at that point I believe that WR was already broken. So, I
think that there is no solution to your problem other than to wait for
Ettus to fix the WR issues. However, WR has been broken for a while
(note user-list posts from last fall Sept & Dec) so I don't know when
this will be working again.

Hi Michael,
I obtained the necessary SFP+ optical adapters and now I am trying to
put uhd 3.13.1.0 on the N321s in order to use the WR synchronization.
Unfortunately, when I update the sd card image with 3.13.1.0 the N321
boots but the SFP0 and SFP1 do not go up. When I try to run
uhd_find_devices, on a terminal using the USB port it says no UHD
devices are found.
I believe that the right FPGA image should be put on the FPGA, but
the
ways described in Knowledgebase are not working.
Is there a way to put the version 3.13.1.0 on the N321? I have tried
version 4.0.0.0 and it is working fine, but WR is broken.
BR,
Vladica
