Hi all,
Maybe this is a basic question but I've been searching for
the solution for a long time. Thanks in advance for helping
me. Here is my situation:
I'm using one laptop connection method to connect two USRP
2920 with MIMO cable. When I plug Ethernet cable into my
laptop, no LED light of the Ethernet port on USRP is on.
Methods I tried:
- removed and connected the ethernet cable again for several
times -- didn't work
- removed and connected the power supply cables for several
times -- didn't work
- used command "uhd_find_devices" in Terminal to check the
hardware connection, turned out "No UHD Devices Found"
- tried command "ifconfig" in Terminal but it didn't show
the ethernet connection
- tried couple of ethernet configuration commands in
Terminal -- didn't work
Previous work I did:
- Successfully burned N210 firmware and FPGA images into
both USRPs
- Connected to another laptop with Ubuntu 12.04 OS, it can
successfully recognize the USRPs; however, I have to use my
laptop to finish the project.
- Used Ethernet cable to connect to my network, it worked
- Tried another laptop with Ubuntu Kylin 16.04 32-bit and
had same problem
My question is: is it an USRP problem or my OS ethernet
setting up problem? if it is my OS problem, how to solve it?
My system info:
- Using latest GNU Radio (I think, because I followed the
installation step by using "apt-get install gnuradio")
- UHD version: 3.010 (followed "package manager method"
from: https://files.ettus.com/manual/page_install.html
)
- OS: Ubuntu 16.04 64-bit
- Two USRP 2920s connected by MIMO cable
Thanks and regards,
Bojun
