Hi,
I have following queries regarding FPGA in USRP2.
1. Data flow for the ADC samples. To which modules does it go, how is it
processed and finally how is it sent out by FPGA.
2. How does the Host and FPGA communicate with each other. Is there an
interrupt being created at the ethernet port and

For anyone who had this problem, the solution I found was specifying which
daughterboard to use, with the "-R" option, and connecting the antenna to
the RX, rather than the TX/RX antenna input. Hopes this helps someone.

I vaguely recall that RFX900 and RFX1800 are essentially the same board,
with only a very small
modification. I wonder if you accidental
Hi,
Yes, I tried both ways, passing the frequency range as a parameter and
inputting it in the GUI.

Ok I will look into that. Another question... I am not sure if you have seen
the code for the usrp_wfm_rcv.py code but in the code there is a little
section where it builds a FFT plot and displays the date. Do you know if
there is anyway of getting the data that it is plotting?
Thanks

Hello Matthias,
thanks again for your help.
As you have possibly seen, I have opened another thread yesterday,
because I wasn't able to burn my card and to get a positiv verification
message. This morning I didn't know what to do anymore and I decided to
try another card writer. And suddenly i

hello everyone !
i use benchmark_ofdm_tx to tramsmit data continuously .but in the receiver
side ,i get serveral packets ,then a serial of noisy, and then useful packets
again .the packets seem discontinuously transmitted .i wonder why .
in my program both fusb_nblock and fusb_block_size are

Hello,
"destination host unreachable" indicates that the route is not set correctly.
Try
# route add -net 192.168.10.0/24 dev eth1
or check
# route -n
to see if the routing is using the proper network devices.

Hi List,
I'm working on a firmware for a completely standalone usrp2 sender.
How is that 32 bits integer dsp_tx_regs->freq interpreted by the
hardware and which value do I need to send e.g. on the 802.11g channel
11 (2.462 GHz)?
Cheers,
Matthias

Hi,
I've got exactly the same problem.
In my case the lights D and F are light up.
The usrp2_card_burner_gui.py works correctly. I've checked that by
flashing the cards with the common firmware.
And that works fine.
