Hello list,
I am trying to get USRP N210 running. I experience a problem when I connect
it to my computer. I see only B and F LEDs on, the Ethernet LEDs are shut
down after about one second of switching on USRP. "mii-tools eth0" outputs
"1000 MBit, half duplex, no link". Wiresharks shows no packet
Hello every one,
I have just started working with GNU Radio Software and USRP2 motherboard.
My ethernet card in the host PC doesn't support Gigabit so I thought to
connect the USRP2 motherboard through a gigabit switch. My question is:
should it work in a normal case?
I think the switch can make

Hello,
in dsp_core_rx.v, what would be the best place to tap the samples for
working at 100MS? Currently, I'm using i_cordic and q_cordic (rounded by

round_isamplefull
(.clk(clk),.in(i_cordic),.out(i_sample_full_scaled))"), but the block
Gregor,
I am curious - what are you going to do with samples ? - store on in RAM or
send them somewhere else ?
Unfortunately, I have no clue about the question.

Hi everyone, im a student from the ETS of Montreal, so excuse my english plz.
I have to recompile the USRP2 fpga project because i will use the mictor conn
to talk with another fpga. First, I tried to compile the original project, the
one in the directory git://ettus.sourcerepo.com/ettus/fpga.
Hi all,
I want to send and receive data between two different USRP1 (both directly
connected) using the GMSK modulation at 30 MHz. I am using the GMSK mode
implemented in GNU Radio. For transmission, I am using the LFTX daughterboard
and for reception, the BasicRX.
As a result, when I transmit

Hey Josh,
thanks a lot. Now it works.
I'll try to implement algorithms soon.
But this should be a first step.

Hi,
is the USRP2 starting at all, with LEDs on and the fan running? Was it running
before? We had the problem that the fuse on the USRP2 was blown. Its rather
easy to replace once you identified it as the problem.

There is no aeMB so there is no firmware in the sense that we have on the

Interesting - those interrupts

I'm attempting to expand on a custom FPGA build I've been working on. The
