Hello all, I'm trying to ramp up on the progress that the UHD has been making lately. Initially, I'm using the stable FPGA bitstream and firmware binaries from July 6th, which can be downloaded from:
http://code.ettus.com/redmine/ettus/projects/public/wiki/U2binaries#UHD-Firmware-and-FPGA-Images I got libuhd built, and after a bit of mucking around was able to get uhd_find_devices to see my USRP2. However, when I went to run benchmark_rx_rate with my USRP2 + RFX2400 (rev30, dated 12/2/2006), I'm seeing a warning where the dboard doesn't seem to be recognized. Here is a snippet of output from benchmark_rx_rate: [r...@epiq-laptop1 examples]# ./benchmark_rx_rate Creating the usrp device with: ... Target recv sock buff size: 50000000 bytes Actual recv sock buff size: 131071 bytes Warning: The recv buffer is smaller than the requested size. The minimum recommended buffer size is 50000000 bytes. See the USRP2 application notes on buffer resizing. Warning: unknown dboard-id or dboard-id combination: unknown (0xffff) -> defaulting to the unknown board type Warning: unknown dboard-id or dboard-id combination: Flex 2400 MIMO B TX (0x002b) -> defaulting to the unknown board type Using: Unknown - unknown (0xffff) Using: Unknown - Flex 2400 MIMO B TX (0x002b) RX samples per packet: 362 TX samples per packet: 363 Recv pirate num frames: 89 Using Device: Simple USRP: Device: usrp2 device Mboard: usrp2 mboard0 - rev 4:0 RX DSP: usrp2 ddc0 RX Dboard: usrp2 dboard (rx unit) RX Subdev: Unknown - unknown (0xffff) TX DSP: usrp2 duc0 TX Dboard: usrp2 dboard (tx unit) TX Subdev: Unknown - Flex 2400 MIMO B TX (0x002b) OTesting receive rate 0.500000 Msps (10.000000 second run) Received packets: 13813 Received samples: 5000306 Lost samples: 0 Lost packets: 0 (approximate) Sustained receive rate: 0.500000 Msps <snip> Other than the fact that the socket buffers need to be increased, it appears as though it works. But the warning indicating (twice?) that there is an unknown dboard-id/board type is concerning. I've seen traffic of other folks using UHD + the RFX2400, such as: http://www.mail-archive.com/discuss-gnuradio@gnu.org/msg24051.html ...so I'm fairly certain the RFX2400 is supported. Any ideas as to what the issue could be here? Any insight is appreciated. -- John Orlando CEO/System Architect Epiq Solutions www.epiq-solutions.com _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
