Hi there, I'm writing a simple block to do some GSM processing, which right now just looks for FCCH in the signal. The graph is constructed as follows: usrp->low pass filter->gmsk.demod->my_block. My block inherits from gr_sync_block. The problem I run into is the following assertion failing: "gr_buffer.h:125: unsigned int gr_buffer::index_add(unsigned int, unsigned int): Assertion `s < d_bufsize' failed." This happens shortly after I start the program. I tried removing any processing by my block and just returning noutput_items in the work() function, which didn't help. I then removed the demodulator from the graph to see if the assertion would still fail and the program ran fine. Is the gmsk.demod block too slow? What other reasons are there for this error?
Thank you. -- Cheers, Timur _______________________________________________ Discuss-gnuradio mailing list [email protected] http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
