Hi Francisco,
I had the same problem with a brand new N321. Deleting, downloading again and
reloading the FPGA image from the host did the trick in my case.
Note: I did't try to reproduce the condition so I'm not 100% sure of validity
of the solution, just saying it's worth a test.
Best,
Lorenzo

Subject: [USRP-users] E312 fails to run uhd_usrp_probe from host
Hi all,
I'm trying uhd_usrp_probe on my host to get information of my E312 (when I run
it locally on the E312 it's fine), and it fails to get the data with the
following error:
me@myhost: ~/rfnoc/uhd$ uhd_usrp_probe --args type=e3xx,addr=192.168.3.2
[INFO] [UHD] linux; GNU C++ version 8.3.0; Boost_106700;

Have you seen this kind of error for E310/E310?
Does E312 accept requests from the host?
I did manage to load the FPGA image from the host by running:
me@myhost:~rfnoc/uhd$ uhd_image_loader --args type=e3xx,addr=192.168.3.2
The sdcard image on the E312 is the one from
http://files.ettus.com/binaries/cache/e3xx/meta-ettus-v3.15.0.0/e3xx_e310_sg3_sdimg_default-v3.15.0.0.zip,
and I think the UHD version on the E312 matches the one on the host:
root@ni-e31x-30D84C7:~# uhd_config_info --version
UHD 3.15.0.0-0-gaea0e2de
me@myhost: ~/rfnoc/uhd$ uhd_config_info --version
UHD 3.15.0.HEAD-0-gaea0e2de
Any clue?
Many thanks!
Francisco
