I have created two GRC files to run as examples, attached. The issue only occurs when the Transmit file is started after the Receive file (i.e. the Receiver is already running). And the same error occurs in GNU Radio 3.7.3 on Windows. Thanks, Luke From: address@hidden [mailto:address@hidden On Behalf Of PEEL Luke All, I am running a basic PSK Mod block in one GRC flowgraph and another flowgraph with a basic PSK Demod. I am using two URSP N210s, one as transmit, one as receive and GNU Radio 3.7.5, built on Ubuntu with Debugging Symbols. If I start the PSK Mod, while the Demod flowgraph is running, I get assertion failures. The following is printed in the ‘top_block’ Python output window: This early on: (python:3210): Gtk-CRITICAL **: IA__gtk_progress_set_percentage: assertion 'percentage >= 0 && percentage <= 1.0' failed And this later on: python: /home/luke/gnuradio-3.7.5/gnuradio-runtime/include/gnuradio/buffer.h:170: unsigned int gr::buffer::index_add(unsigned int, unsigned int): Assertion `s < d_bufsize' failed. Which then causes (in the GDB output): Program received signal SIGABRT, Aborted. 0xb76f4424 in __kernel_vsyscall () Does anyone have any idea where to start with this? Or can anyone reproduce the same problem? Thanks, Luke |
