Hi all, I had received a USRP (Rev 4.5) from someone. The USRP was modified to operate in slave mode. First I opened it and powered on; the LED was blinking. So I did the following. 1. turned it OFF and open circuited R2030 and short-circuited R2029 2. move C926 to C925 3. added C924 4. powerd on the USRP; the LED was OFF 5. checked the onboard clock by probing at J2002 and got a 64MHz sinusoidal(?) waveform on my oscilloscope. that means the power supply is okey and the clock is working right? 6. I run usrp examples, and got the following error.
usrp: failed to find usrp[0] Tracback most recent calls last): File "./usrp_wfm_rcv.py", line 297, in <module> ... ... File "/usr/lib/python2.6/dist-packages/gnuradio/usrp/usrp_swig.py", line 1646, in source_c return _usrp_swig.source_c(*args, **kwargs) RuntimeError: can't open usrp I get the same error message when I run this code without the USRP; the only difference is that it hangs for about 3 minutes before printing the message when the USRP is connected. I checked the var/log/messages file and got the following ... ...
