I do not get a ping back from 192.168.10.2 either.
Here is what I have:
-Ubuntu 10.04
-USRP2 with stock SD card and firmware, no daughterboards
-UHD+gnuradio installed yesterday using the Leech script from http://www.sbrac.org/files/build-gnuradio
-Gigabit Ethernet
-PC IP set to: 192.168.10.1, netmask: 255.255.255.0
-Firewalls disabled (inactive)
Here is what happens:
When I power up the usrp2 (with ethernet connected)
-All 6 LEDs briefly flash followed by D & F lit.
-Ethernet green lights on.
-Ethernet orange light flashes every time it gets pinged.
So, I have all the good signs and everything should be set up correctly.
However uhd_find_devices returns No UHD Devices Found and I do not get a
ping back from 192.168.10.2 either.
I have also tried uhd_usrp_probe --args “addr=192.168.10.2” which
returns no
devices found as well.
The stock firmware on the USRP2 (which was released prior to the
invention of UHD), doesn’t
support UHD. You’ll have to burn the appropriate image into the USRP2
for it to support UHD.
The UHD “wire protocol” has undergone several revisions in the last
year as well, so it’s good to
have your USRP2 firmware match the host-side software. Further, the
stock USRP2 firmware
doesn’t have an IP stack at all–it used so-called “raw ethernet”
frames for communications, so it’s
not able to respond to pings, which use the ICMP ECHO (part of IP)
protocol.
You’ll find that the build-gnuradio script will have installed firmware
images in:
/usr/local/share/uhd/images
And you can use /usr/local/share/uhd/utils/usrp2_card_burner_gui.py to
place new firmware and FPGA
images onto your USRP2 SD card.
