[Discuss-gnuradio] Getting USRP N210 running

2010-12-14 Thread Vadim Uvin
Hello list, I am trying to get USRP N210 running. I experience a problem when I connect it to my computer. I see only B and F LEDs on, the Ethernet LEDs are shut down after about one second of switching on USRP. mii-tools eth0 outputs 1000 MBit, half duplex, no link. Wiresharks shows no packets

Hello, in dsp_core_rx.v, what would be the best place to tap the samples for working at 100MS? Currently, I'm using i_cordic and q_cordic (rounded by something like round_reg #(.bits_in(24),.bits_out(16)) round_isamplefull (.clk(clk),.in(i_cordic),.out(i_sample_full_scaled))), but the block

Thanks for your answer Thomas! Our observations shows also that the usrp2 doesn't drop any samples when an underrun occur. If we drop samples at the host, can we get a continous stream of sample at 25Msamp/s that is synchronous? What is your maximum continous bandwidth? Underflows occur
