I am facing Overrun issue on 500K sampling rate with USRPN210. I see an 'O' after irregular time intervals when I use my flowgrpah . PC is directly connected to USRP with Ethernet cable. PC details:
Processor: Intel® Core™ i7-2600 CPU @ 3.40GHz × 8 Memory: 3.8GiB GNU C++ version 4.6.3; Boost_104601; UHD_003.005.000-26-gb65a3924 Gnruadio version: 3.6.3rc0 Also to check, I ran ./benchmark_rate --rx_rate 500e3 --duration 300, three times and following are the outputs: Testing receive rate 0.500000 Msps OO Benchmark rate summary: Num received samples: 149997045 Num dropped samples: 726 Num overflows detected: 2 Testing receive rate 0.500000 Msps Benchmark rate summary: Num received samples: 149998497 Num dropped samples: 0 Num overflows detected: 0 Testing receive rate 0.500000 Msps OOO Benchmark rate summary: Num received samples: 149997408 Num dropped samples: 1089 Num overflows detected: 3 What could be the issue here? And what can I do to fix this issue as I am losing 3 to 4 packets in every 10k packets when I use my flow-graph. Any comments would be appreciated. -- Best Regards, Sam
