[Discuss-gnuradio] USRP2 Block RAMs Requiring Empty Multipliers

I'm trying to make some modifications to the FPGA of the USRP2 which involves using more multipliers and I came across this error during the Mapping phase of the compile: ERROR:Place:665 - The design has 31 block-RAM components of which 13 block-RAM components require the adjacent multiplier si

[Discuss-gnuradio] USRP2 External Clock

I'm wondering if it is possible to connect the USRP2 to an external 100MHz clock like the USRP was able to be modified so it could connect to an external 64MHz clock. I don't see any place to solder on a SMA connector but there are a set of pins labeled Test CLK. Could that be used for inputting an

I'm looking to model the rx_chain of the USRP using MATLAB's fixed point toolbox and I'm wondering if anyone has tried this yet in MATLAB or Octave. Thanks, Kyle ___ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org http://lists.gnu.org/mailman/li

Re: [Discuss-gnuradio] 1 PPS input for old USRP board

You can connect the 1PPS to the digital io pins on the basic or lf daughtercards. From there you can use the read_io() method in python to read the value on the pins. Just make sure that your 1PPS is between about 1.5 and 3.3V; under 1.5V it may not be detected, over 3.3V you could fry a pin. -Kyl
