Hi. Now it works!!! The procedure is to: 1. add the line: blacklist dvb_usb_rtl28xxu into the file /etc/modprobe.d/raspi-blacklist.conf 2. reboot
Many thanks! A question: there is a way to start "rtp_tcp" in silent mode (without messages on the terminal)? Thanks! 73 Fabio, IZ8MBW www.iz8mbw.net >________________________________ > Da: András Retzler <[email protected]> >A: IZ8MBW Fabio <[email protected]>; [email protected] >Inviato: Lunedì 23 Dicembre 2013 13:46 >Oggetto: Re: RTL2832U on Raspberry Pi > > > >Hi Fabio, > > >I think you should run the following before running any rtl_* commands: >sudo rmmod dvb_usb_rtl28xxu > > >You may also blacklist the dvb_usb_rtl28xxu kernel module, so it won't load >when you plug in the RTL device. > > >73! > > >Andras, HA7ILM > > > > > >2013/12/23 IZ8MBW Fabio <[email protected]> > >Hi. >>I'm trying to install OSMOSdr on a Raspberry Pi. >>I'm following this guide: >>http://www.hamradioscience.com/raspberry-pi-as-remote-server-for-rtl2832u-sdr/ >> >> >>After installing I try to test the RTL2832 USB SDR but I have this error: >> >> >>root@raspberrypi:~/rtl2832/rtl-sdr/build# rtl_test >>Found 1 device(s): >> 0: Generic RTL2832U OEM >> >> >>Using device 0: Generic RTL2832U OEM >> >> >>Kernel driver is active, or device is claimed by second instance of librtlsdr. >>In the first case, please either detach or blacklist the kernel module >>(dvb_usb_rtl28xxu), or enable automatic detaching at compile time. >> >> >>usb_claim_interface error -6 >>Failed to open rtlsdr device #0. >> >> >> >> >>This is my lsmod: >> >> >> >>root@raspberrypi:~# lsmod >>Module Size Used by >>tun 18459 2 >>i2c_dev 5557 0 >>w1_therm 2921 0 >>w1_gpio 2363 0 >>wire 24832 2 w1_gpio,w1_therm >>cn 4783 1 wire >>snd_bcm2835 16165 0 >>evdev 9419 1 >>r820t 16279 1 >>rtl2832 8020 1 >>snd_soc_bcm2708_i2s 5474 0 >>regmap_mmio 2806 1 snd_soc_bcm2708_i2s >>dvb_usb_rtl28xxu 14333 0 >>dvb_usb_v2 14860 1 dvb_usb_rtl28xxu >>rc_core 16313 3 dvb_usb_rtl28xxu,dvb_usb_v2 >>rtl2830 7378 1 dvb_usb_rtl28xxu >>snd_soc_core 131268 1 snd_soc_bcm2708_i2s >>dvb_core 92797 3 rtl2830,rtl2832,dvb_usb_v2 >>regmap_spi 1897 1 snd_soc_core >>snd_pcm 81593 2 snd_bcm2835,snd_soc_core >>snd_page_alloc 5156 1 snd_pcm >>regmap_i2c 1645 1 snd_soc_core >>snd_compress 8076 1 snd_soc_core >>snd_seq 53769 0 >>snd_timer 20133 2 snd_pcm,snd_seq >>snd_seq_device 6473 1 snd_seq >>leds_gpio 2059 0 >>led_class 3688 1 leds_gpio >>snd 61291 7 >>snd_bcm2835,snd_soc_core,snd_timer,snd_pcm,snd_seq,snd_seq_device,snd_compress >>i2c_bcm2708 3949 0 >> >> >> >> >>This is a portion of /var/log/messages >> >> >>. >>. >> >>. >>Dec 23 13:15:06 raspberrypi kernel: [ 2.369348] usb 1-1: new high-speed >>USB device number 2 using dwc_otg >>Dec 23 13:15:06 raspberrypi kernel: [ 2.377867] Indeed it is in host mode >>hprt0 = 00001101 >>Dec 23 13:15:06 raspberrypi kernel: [ 2.387121] devtmpfs: mounted >>Dec 23 13:15:06 raspberrypi kernel: [ 2.399736] Freeing unused kernel >>memory: 144K (c0572000 -
