Hi every body,

Do you know where I can found information to add our own project to CGRAN?

I don't see any information about that on GNURADIO website.

Hi Maxime

Write a recipe for PyBOMBS, make a Pull Request on Github to get it into
the gr-etcetera repo :)

Best regards,

Marcus

Subject: [Discuss-gnuradio] GNU Radio/No Devices Found (NI USRP-2920)
Message-ID: <address@hiddennabble.com>
Content-Type: text/plain; charset=us-ascii

Two programs, MATLAB and GNU Radio, are giving me different results when
searching for the USRP on my network.
My setup is Laptop -> Wired Ethernet -> Switch -> NI USRP-2920.

MATLAB can detect the USRP device, while GNU Radio throws an error whenever
it tries to identify the USRP device at 192.168.10.3.
<http://gnuradio.4.n7.nabble.com/file/n63451/RUBYFORUM_001.jpg>
<http://gnuradio.4.n7.nabble.com/file/n63451/RUBYFORUM_002.jpg>

My computer is configured with the static IP address 192.168.10.1. I'm
using Windows 10 for this setup. I recently downloaded the automated
NI-USRP driver software. Apparently, this software updates the USRP image to
the latest firmware. Installing new firmware onto the USRP had no effect on
the error message.

How do I get GNU radio to detect my USRP device?

If there is any help, I'd be very grateful.

Thanks!

Hello,

I recommend joining the USRP users mailing list and asking your question
there. MATLAB and the Windows GNU Radio install both include their own UHD
drivers so this is likely a conflict between those two and the FPGA version
you have just loaded using the NI-USRP utility. These are three separate
environments, each with their own requirements about the UHD and FPGA
images. We would need to see more of the output for each tool. Can you
please copy and paste the full output from running uhd_find_devices which
is included in the GNU Radio install?

Could you perhaps give us the exact text of the error message?

MATLAB-packaged UHD and GnuRadio-compatible UHD may well have different
firmware requirements.

Also, the firmware doesn't "take effect" until you power-cycle the device.

Also, you should run "uhd_images_downloader" from the
Gnuradio-compatible UHD that you may have, which will identify the
version of the UHD
library you're running, and download the appropriate firmware into
your PC. Once that happens THEN you need to program the FPGA of the USRP
device with this firmware, and power-cycle.

But again, my understanding is that MATLAB packages their own UHD
version, so if you want to use both MATLAB and Gnu Radio, you'll be in
a switching-back-and-forth mode with the firmware.

Okay, here is the console for the error. Let me know if this is what you guys
wanted to see...
<http://gnuradio.4.n7.nabble.com/file/n63454/FORUMS_002.jpg>

I ran the "uhd_image_downloadeder" and it gave me tons of different images.
I'm assuming I'd want to install the N21x_fw and N21x_fpga files. Are there
better ones suited for the USRP-2920?
<http://gnuradio.4.n7.nabble.com/file/n63454/FORUMS_003.jpg>

And finally, I couldn't find the program that allows me to see the images
already installed, but due to the last update of the firmware being
yesterday, I'm fairly confident these images are the ones installed
currently.
<http://gnuradio.4.n7.nabble.com/file/n63454/FORUMS_001.jpg>

I'm concerned that the image status is reading a null value currently.
However, it still reads in MATLAB just fine.

Which images should I install from that repository seen in the second
picture?

Thanks!

Hi,

as Derek said, can you please take this to the USRP-users mailing list?
GNU Radio and UHD are different things...

Best regards and thank you

Subject: [Discuss-gnuradio] Adding command port to OFDM Allocator
Block

Hi,

I am trying to add a command port to the OFDM Allocator block in GNURadio.
The goal is for this command port to take a message every 1 ms to change
the amplitude of the complex pilot symbols. However, I can not see the port
appearing in GRC.

I just wrote some test code to see if the port is appearing. The changes I
made are given below:

*1)* I added this line here:
ofdm_carrier_allocator_cvc_impl::ofdm_carrier_allocator_cvc_impl
{int fft_len,
const std::vector<std::vector<int> > &occupied_carriers,
const std::vector<std::vector<int> > &pilot_carriers,
const std::vector<std::vector<gr_complex> > &pilot_symbols,
const std::vector<std::vector<gr_complex> > &sync_words,
const std::string &len_tag_key,
const bool output_is_shifted
) : tagged_stream_block("ofdm_carrier_allocator_cvc",
io_signature::make(1, 1, sizeof (gr_complex)),
io_signature::make(1, 1, sizeof (gr_complex) * fft_len), len_tag_key),
d_fft_len(fft_len),
d_occupied_carriers(occupied_carriers),
d_pilot_carriers(pilot_carriers),
d_pilot_symbols(pilot_symbols),
d_sync_words(sync_words),
d_symbols_per_set(0),
d_output_is_shifted(output_is_shifted)
{
//MY_CHANGES
*message_port_register_in(pmt::mp("test"));*
* set_msg_handler(pmt::mp("test"), boost::bind(&mac_impl::test_in, this,
_1));*

*2)* And then the function test_in is just a function printing out the
message "TESTER"

//MY_CHANGES
*void test_in (pmt::pmt_t msg) {*
* // this must be a pair*
* int count = 0;*
* if (!pmt::is_blob(pmt::cdr(msg))) {*
* throw std::runtime_error("PMT must be blob");*
* }*

* if(pmt::is_symbol(msg)) {*
* throw std::runtime_error("#############TESTER#########");*
*}*
*}*

*3) *I uninstalled everything and built again. But I cant see anything in
the block. I don't see this port at the input of the block.

Can anyone please tell me what am I doing wrong ?

Hi,

did you add the message port to the .xml file describing the block in
python?

Greetings,
