[Discuss-gnuradio] Marvell Yukon 88E8039 PCI-E Ethernet - USRP2

Hi I recently installed fedora 9 and GNU radio on laptop computer (COMPAQ Presario V3700, Marvell Yukon 88E8039 PCI-E Ethernet) but USRP2 is not recognized. (Running "find_usrp" keeps printing "No USRP2 found.") I have been using USRP2 with other desktop PCs and laptop PCs and I think there is no

The new I7 intel processors have a really amazing amount of horsepower but a tremendous amount of onboard stuff is designed to work intimately with the peripherals to bring on high speed graphics. Now if your argument is that all of this is going to be moved into the GPP, I might agree that we wi

G'day, I'm glad to inform that replacing the FX2 chip resolved the problem and the USRP appears to be fully operational, e.g. usrp_benchmark and usrp_wfm work out of the box. I since tried to connect the board using a USB2.0 cable of 5m in length and can't establish communication with it. The

There are many more ways than just lumping everything onto a single GPP. A good example is a recent thread on the GNU radio mailing list where the poster is using the USRP2 as a standalone radio with no PC. Pushing key elements to other reconfigurable processors, e.g. the USRP2 FPGA, will grea

Hi, I want to read a byte from a file and send it to an input stream. Each time I read one byte from the file i want to send it onto the input stream of a particular block and then read the next byte and do the same. I looked at gr.message_source() which does similar work to what I need. But I see
