[Discuss-gnuradio] The (in)famous channel 0 not receiving error

[Nick Othieno]

Hi everyone,

I recently compiled and installed gnuradio.

I then tried to find the usrp2:

#find_usrps
00:50:c2:85::3b:5c hw_rev = 0x0400

Next I tried to plot an FFT of the GPS L1 signal (note that my daughterboard is a dbsrx2)

#usrp2_fft.py -f 1.57542G
usrp2: channel 0 not receiving
usrp2::rx_samples() fail

Where am I going wrong? I have seen other posts with people facing the same problem but they are from way back in mid-2010 and with different daughterboards from mine.

Additional information:
- daughterboard is a dbsrx2
- usrp2 was ordered sometime in October 2010
- I have the uhd driver installed but figured that it can exist with the "usual" Ethernet driver
- Are there any firmware and/or fpga upgrades I am supposed to make?
