[Discuss-gnuradio] FPGA update
Dear All, I have got new usrp x310 with UBX160 daughter board, I assembled the usrp, but when I run the uhd_usrp_probe --args addr=192.168.10.2 there is a UHD Warning: *X300 unknown product code in EEPROM:30818* *Error: RuntimeError: Expected firmware compatibility number 3.0, but got 4.0:* *The firmware build is not compatible with the host code build.* *Please run:* * "/usr/local/lib/uhd/utils/uhd_images_downloader.py"* I found from ettus website how I can download and update image ( http://files.ettus.com/manual/page_usrp_x3x0.html#x3x0_hw_1gige) but when I run uhd_image_loader --args="type=x300,addr=192.168.10.2,fpga=HGS", I got from terminal uhd_image_loader: command not found. I need advace, about this problem: *uhd_image_loader: command not found.* *FYI, I use Live_USB.* -- Regards, Diyar Muhammed Ministry of Higher Education and Scientific Research Duty: Network Administration and Design Website: www.mhe-krg.org Cell Phone: 009647504690060 Office Phone: 00964662554683 ___ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org https://lists.gnu.org/mailman/listinfo/discuss-gnuradio

Re: [Discuss-gnuradio] OFDM benchmark optimal parameter
Marcus, I look at ofdm_loopback.grc example, I made the same scenario but I had problem with Error Rate block I got error rate around 4 to 5, as my knowledge that is not right I think should be between 0 to 1. If there is a transceiver example with measure bit error rate that will be helpful for me. in advance thank you.

Re: [Discuss-gnuradio] OFDM benchmark optimal parameter
Dear Marcus, Thank you very much indeed for fast replying. I look at tx benchmark help I could not find rates but there is packet size and megabytes to transmit. so that, which one do you mean packet size or megabytes? it is okay to use USRP B210 for transmitting and receiving by using to benchmark file? because when I used one of them (tx or rx) and then I wanted to run another one the error come up (no device found for empty device address). in advance many thanks.

[Discuss-gnuradio] calculate data rate
Dear ALL for example we use qpsk modulation and 1M sample rate, what is the transmission throughput? data rate -- Regards, Diyar Muhammed Ministry of Higher Education and Scientific Research Duty: Network Administration and Design Website: www.mhe-krg.org Cell Phone: 009647504690060 Office Phone: 00964662554683 ___ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org https://lists.gnu.org/mailman/listinfo/discuss-gnuradio
