Thanks, it's actually working fine, the led properly turned green
after the firmware and gateware were uploaded.
Trying .\benchmark_rate.exe --rx_rate 40e6 I get
Benchmark rate summary:
Num received samples: 201778444
Num dropped samples: 2800
Num overruns detected: 2800
Num transmitted samples: 0
Num sequence errors (Tx): 0
Num sequence errors (Rx): 0
Num underruns detected: 0
Num late commands: 0
Num timeouts (Tx): 0
Num timeouts (Rx): 0
It seems I still can't stream faster than around 28MS/s. I still get
similar results with .\rx_samples_to_file.exe (using --null to not
store to file).
Should I try to run some tests from
http://files.ettus.com/manual/page_rdtesting.html ?
Concerning the error "[ERROR] [USB]
libusb_session_impl::libusb_event_handler_task: LIBUSB_ERROR_CODE
-1" that I get when specifying num_recv_frames, what could I do?
Should I try a different driver? Has anyone already experienced that
error?
Thanks.
Try with a smaller number? The Windows LIBUSB behaves differently
than the Linux version. On Linux, I can usually ask for 256 without
any issue. Try 64.
