Hi, today I uninstall/re-install Ubuntu and reinstall hackrf spiflash and cpldjtag and here is hackrf_info outcome: hackrf_info version: 2017.02.1 libhackrf version: 2017.02.1 (0.5) Found HackRF Index: 0 Serial number: 0000000000000000909864c828721dcf Board ID Number: 2 (HackRF One) Firmware Version: 2017.02.1 (API:1.02) Part ID Number: 0xa000cb3c 0x005e435a
And still I can not run hackrf_transfer mode in OS Ubuntu. Here is one outcome: hackrf_transfer -r /dev/null call hackrf_set_sample_rate(10000000 Hz/10.000 MHz) call hackrf_set_freq(900000000 Hz/900.000 MHz) Stop with Ctrl-C 0.3 MiB / 1.000 sec = 0.3 MiB/second Exiting... hackrf_is_streaming() result: streaming terminated (-1004) Total time: 1.00015 s hackrf_stop_rx() done hackrf_close() done hackrf_exit() done fclose(fd) done exit What should I do?
