when i run it with usrp b210 it's working but when i uncheck checkbox and check again it crashes.

I'm using windows 10 and gnuradio version 3.7.13.4.
(I used checkbox to stop and start the flowgraph)
also when I connect gnuradio blocks from my c++ code and I try to use stop of top_block and start it again it crashes. I also created issue in gnuradio github : https://github.com/gnuradio/gnuradio/issues/2351

Answer 1

My colleague found answer and i fixed it by adding (|| result.status != LIBUSB_TRANSFER_CANCELLED) to condition that checked if transfer is completed in line 142 of branch rfnoc-devel and i sent a pull request https://github.com/EttusResearch/uhd/pull/289
