Re: GR3.8 RTL-SDR: Errors in swig?

[Volker Schroer]

Hi,

does

dmesg

give some hints why the kernel driver was detached ?

I had to blacklist

dvb_usb_rtl28xxu

module to get my dongle running.


Then the output looks like

gr-osmosdr 0.2.0.0 (0.2.0) gnuradio 3.9.0.0-git
built-in source types: file rtl rtl_tcp rfspace redpitaya
Using device #0 Generic RTL2832U SN: 77771111153705700
Found Rafael Micro R820T tuner
[R82XX] PLL not locked!
[R82XX] PLL not locked!
Allocating 15 zero-copy buffers
