Hello All,
I have a Segmentation fault (core dumped), when i run digital_bert_rx.py and digital_bert_tx.py. ./digital_bert_rx.py -f 2460M --rx-gain=30 --args="addr=192.168.10.2" ./digital_bert_tx.py -f 2460M --tx-gain=30 --args="addr=192.168.10.3" --amplitude=0.2 When I run for a sevral times digital_bert_tx.py with diffirent values of amplitude this error apear, like in this capture. Freq. Offset: -124987 Hz Timing Offset: 1493639.0 ppm Estimated SNR: nan dB BER: 0.166678 Freq. Offset: -124938 Hz Timing Offset: 1492926.4 ppm Estimated SNR: nan dB BER: 0.16616 Freq.

Offset: -124862 Hz Timing Offset: 1481416.7 ppm Estimated SNR: nan dB BER: 0.166141 Segmentation fault (core dumped) I tried to debug the error and I found that the error was comming from a gnuradio kernel. The segmentation error is from this file : volk_32fc_32f_dot_prod_32fc.h Program received signal SIGSEGV, Segmentation fault. [Switching to Thread 0x7f6cdaffd700 (LWP 5423)] 0x00007f6cf51d2e87 in volk_32fc_32f_dot_prod_32fc_a_sse () from /usr/local/lib/libvolk.so.0.0.0 Can you help me please. |
