Dear community， I'm a new user of USRP N310. I follow this guide https://kb.ettus.com/USRP_N300/N310/N320/N321_Getting_Started_Guide and now I can connect to N310 by RJ45 port. I have completed the Linux File System update. When I try to update FPGA images, it said "No applicable UHD devices found". Why does this happen? Any advice would be appreciated.

I'm not sure if N320/N321 are supported in UHD v.3.13. You should use UHD v.3.15 unless you have a compelling reason not to. On Mon, Jul 13, 2020 at 6:30 PM Marcus D.

 Can you "ping" the USRP device from your host?  That's the first
 diagnostic step.  Has it (the USRP) changed addresses?

Yes, I can "ping" the USRP address derived from command "uhd_find_devices", for example, "192.168.1.191". I also try to update FPGA in ARM CPU mode but it still says "NO applicable UHD devices found". Regards, Heng Marcus D.

I am simply parrotting the Getting Started Guide, which says in bold letters at the very top: *When you receive a brand-new device, it is strongly recommended that you download the most recent filesystem image from the Ettus Research website and write it to the SD card that comes with the unit. It is not recommended that you use the SD card from the factory as-is. Instructions on downloading the latest filesystem image and writing it to the SD card are listed below.* *Note that if you are operating the device in Network Mode, the version of UHD running on the host computer and the USRP N3xx must match.* Recent N310s are most likely shipping with SD cards that have a UHD version >3.13.

Dear all, The problem has been resolved by updating the UHD version to v3.15.0.0. By the way, is there any information about the UHD versions that support N310?

     OK, so when you follow the steps here:
