[Hackrf-dev] Raspberry Pis and HackRFs

[Rustu Yucel]

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?
