View all threadsRFNoC OOT module not found in GNURadio
Hi all,
I'ḿ trying to instance in my GNURadio graph the splitstream rfnoc block.
I'm using RFNoC 4.0, GNURadio3.8 and gr-ettus master branch.
This block has all the UHD driver and verilog code in the UHD repository
(under
"~/rfnoc/src/uhd/fpga/usrp3/lib/rfnoc/blocks/rfnoc_block_split_stream",
"/rfnoc/src/uhd/host/lib/rfnoc" and
"/rfnoc/src/uhd/host/include/uhd/rfnoc), but it is not included in
gr-ettus/gnuradio, so I try to create an OOT module using this code to use
the block on GNURadio.
I have successfully created the module with rfnocmodtool, adapted the
verilog, c++ and yml files and compiled and installed the block. I have
generated an image using the block and uhd_usrp_probe seems to recognise
the block:

I have a graph on GNURadio with the created block (attached), but when I
try to run it I have the following error:
Traceback (most recent call last):
File "QPSK_example.py", line 386, in <module>

line 243, in make
return _splitting_swig.splitstream_make(graph, block_args,
device_select, instance)
RuntimeError: Cannot find block!
I'm not very familiar with swig so, is there something I must add in the
swig interface to have my block recognised by GNURadio? Or is this error
related to something else? I'd really appreciate any help on this.
Kind Regards,
Maria.
I second this. I’m having almost the exact same issue with split stream.
Mine returns attribute error no module found, but as shown in Maria’s post, it’s displayed fine in grc and the image.

Oh! I hope someone can tell us what might be wrong with the block. Have you
got another OOT block working created with rfnocmodtool? Just to discard
the tool as the problem.
If I figure out something new I'll tell you.
Kind regards,
Maria

Hi again,
I still have the same error that I post before but I have made some tests.
First I test an OOT empty block created with rfnocmodtool (just loop back
the input to the output in the Verilog part as the tool does by default).
This block works (partially) in GNURadio (it gives recv timeouts but it
doesn't complain about no found block), so I think this is a specific
problem with the splitstream block.
I have realized that the name of the block that "uhd_usrp_probe" recognizes
doesn't match with the name I give to my OOT splitstream block. I have made
2 blocks, one named "splitstream" and another named "split". In both cases,
"uhd_usrp_probe" says that the block is named "SplitStream". That makes me
think that "uhd_usrp_probe" is finding the UHD controller that is in the
UHD repository and not the one created for my OOT block (in that case the
name would be a generic one, "block"). Why does this happen? I have only
modified the Verilog part with the one that comes in UHD and I haven't
found anything related to the controller on it, so it does not make sense
to me.
Can be this related to the problem? I have also tried to change the ID of
the block but this still doesn't work. Any new ideas on your side Paul?
Someone can help us?
Kind Regards,
Maria

I have a graph on GNURadio with the created block (attached), but when I
try to run it I have the following error:
Traceback (most recent call last):
File "QPSK_example.py", line 386, in <module>
main()
File "QPSK_example.py", line 362, in main
tb = top_block_cls()
File "QPSK_example.py", line 86, in init
self.splitting_splitstream_0 = splitting.splitstream(
File
"/usr/local/lib/python3/dist-packages/splitting/splitting_swig.py", line
243, in make
return _splitting_swig.splitstream_make(graph, block_args,
device_select, instance)
RuntimeError: Cannot find block!
I'm not very familiar with swig so, is there something I must add in the
swig interface to have my block recognised by GNURadio? Or is this error
related to something else? I'd really appreciate any help on this.
Kind Regards,
Maria.

It sounds like Neel Pandeya could jump on the forum and answer our questions quickly as these are deeply RFNoC-centric.
I caught the same bug with the block naming being dissimilar and corrected it to exact syntax.
At this point I’ve gotten the block to “sort of” work as well. I get U/L’s and the block doesn’t like the multiple streams. I believe that each of the outputs needs a streaming end point. So SEP#5 would be in/out0, but SEP#6 would be out1. Wouldn’t that make more sense? The fosphor block has that configuration in my custom fosphor image.

Hi again,
I still have the same error that I post before but I have made some tests.
First I test an OOT empty block created with rfnocmodtool (just loop back the input to the output in the Verilog part as the tool does by default). This block works (partially) in GNURadio (it gives recv timeouts but it doesn't complain about no found block), so I think this is a specific problem with the splitstream block.
I have realized that the name of the block that "uhd_usrp_probe" recognizes doesn't match with the name I give to my OOT splitstream block. I have made 2 blocks, one named "splitstream" and another named "split". In both cases, "uhd_usrp_probe" says that the block is named "SplitStream". That makes me think that "uhd_usrp_probe" is finding the UHD controller that is in the UHD repository and not the one created for my OOT block (in that case the name would be a generic one, "block"). Why does this happen? I have only modified the Verilog part with the one that comes in UHD and I haven't found anything related to the controller on it, so it does not make sense to me.
Can be this related to the problem? I have also tried to change the ID of the block but this still doesn't work. Any new ideas on your side Paul? Someone can help us?
Kind Regards,
Maria

Oh! I hope someone can tell us what might be wrong with the block. Have you got another OOT block working created with rfnocmodtool? Just to discard the tool as the problem.
If I figure out something new I'll tell you.
Kind regards,
Maria

I second this. I’m having almost the exact same issue with split stream.
Mine returns attribute error no module found, but as shown in Maria’s post, it’s displayed fine in grc and the image.

Hi all,
I'ḿ trying to instance in my GNURadio graph the splitstream rfnoc block. I'm using RFNoC 4.0, GNURadio3.8 and gr-ettus master branch.
This block has all the UHD driver and verilog code in the UHD repository (under "~/rfnoc/src/uhd/fpga/usrp3/lib/rfnoc/blocks/rfnoc_block_split_stream", "/rfnoc/src/uhd/host/lib/rfnoc" and "/rfnoc/src/uhd/host/include/uhd/rfnoc), but it is not included in gr-ettus/gnuradio, so I try to create an OOT module using this code to use the block on GNURadio.
I have successfully created the module with rfnocmodtool, adapted the verilog, c++ and yml files and compiled and installed the block. I have generated an image using the block and uhd_usrp_probe seems to recognise the block:
