Re: [Discuss-gnuradio] GNU Radio scheduler behavior

Apparently the issue was some USB block sizing that was happening in the flowgraph, a flowgraph that someone in my research lab provided, when I enabled scheduler logging as per Eric's suggestion I found that the scheduler wasn't calling the work function at all. When I enabled logging from t

Re: [Discuss-gnuradio] GNU Radio scheduler behavior

1- GNU Radio 3.2.1 2- I'm not running out of CPU cycles 3- I've been dissecting the filtering blocks in GNU Radio in hopes of doing the same on the DSP. It's my understanding that the filter can process (noutput_items + ntaps) for each iteration. For DSP filtering, I've tried just copy

[Discuss-gnuradio] GNU Radio scheduler behavior

I think I'm running into some scheduler issues in GNU Radio that I don't really understand. I've been working on running GNU Radio blocks on the Beagleboard's DSP by writing new DSP specific custom signal processing blocks When I run simple QA python test scripts everything works fine. If I st

[Discuss-gnuradio] Gnuradio/Beagleboard modifying flow graph buffer allocation

hi, I'm working on Gnuradio on the Beagleboard. I've managed to successfully integrate the DSP as a custom signal processing block and I'm essentially using TI library based buffers to transimt data between the GPP and DSP. I'm trying to use pointers to copy data to and from the DSP instead of

[Discuss-gnuradio] Adding Static Library Links with Custom GNU radio blocks

hi, I am trying to compile the "gr-howto-wtite-a-block-3.2.2" and link an external static library to it. I've enabled "howto_la_swig_ldflags" and added the directory to the static library in it and enabled the "howto_la_swig_libadd" and added the static library name to it. While observing t

[Discuss-gnuradio] GNU Radio + Beagleboard Question

I've been trying to check the performance of GNU Radio running on the Beagleboard and I was wondering if anyone has tried running the benchmark_tx and/or benchmark_rx scripts on them. When I was running benchmark_tx with dbpsk with symbol rate of 125k and a packet size of 1000 bytes the script

[Discuss-gnuradio] USRP2 firmware + cross compiled GNU Radio question

Hi, I've been working on cross compiling the latest stable GNU Radio release, 3.2.1, onto the TI Davinci DM6446 board using OpenEmbedded as my build environment and Angstrom as my Linux Distro. I've managed to cross compile and download gnuradio onto the board, though I'm going with a console o

[Discuss-gnuradio] Usrp2 Fpga Synthesis Question - Ucf related

Hi, I've recently started looking at the Spartan3 ISE projects.? I started trying to re-synthesize the ISE projects, while using the "u2_rev3.ucf" file, I realized that I had to enable the "Allow Unmatched LOC Constraints" option, which seems okay since some declared signals might be used.? How

[Discuss-gnuradio] Question about Benchmark_rx.py file code

Hi I'm trying to troubleshoot a piece of code that was handed to me.? The basic application uses GNU radio and a USRP in transmitting digital signals and the application uses the following file provided in GNU radio "benchmark_rx.py" which can be found in the following directory "gnuradio/trunk
