Rob,
I am using UHD 3.15. Thanks for pointing me to the section in the
...builder.py script. I noticed that it is finding the source files
correctly and generating the include file "Makefile.OOT.inc". However,
the include file was not part of "Makefile.e31x.inc". I did a grep
search for Makefile.OOT.inc and found it in the n3xx and x300
directories. So, when I added it to the e31x directory (i.e. in
Makefile.e31x.inc) the build script was able to locate all the source
files and Vivado was able to continue its build.
Thanks so much for your insight,
Mike

Mike,
Are you using UHD 3.15? If so, I suspect that UHD itself is the issue
- particularly the uhd_image_builder.py script. My own experience is
that starting around 3.15, some things changed in the
uhd_image_builder.py script and caused issues in finding OOT files.
Take a look in the python create_oot_include() procedure and you will
find an if/elif statement that looks for Makefile.inc or Makefile.srcs
in various paths in the OOT folder such as rfnoc/ or rfnoc/fpga-src.
Attached are the files Makefile.inc that I have in my rfnoc/ and
rfnoc/fpga-src folders. You could modify these for your own specifics
and re-try the uhd_image_builder.py script.

Hi,
I've been going through AN-823 (Getting started with RFNoC
Development)
and have successfully gotten through the point of simulating the gain
test bench with positive results.
I'm attempting to build the FPGA now with the new OOT module. I've
successfully built with only pre-existing modules and seen it work
in my
hardware (E310).
My command is as follows:
~/prefix/rfnoc2/src/uhd-fpga/usrp3/tools/scripts$
./uhd_image_builder.py
gain ddc fft -t E310_RFNOC -d e31x -I
/home/mike/prefix/rfnoc2/src/rfnoc-tutorial/rfnoc/
I used the gui command ./uhd_image_builder_gui.py but it does not
create
the correct device type (-d E310 vs -d e31x).
I've tried using "-I /home/mike/prefix/rfnoc2/src/rfnoc-tutorial/"
to no
avail either.
So, it seems like I'm missing a path somewhere in the makefiles that
keeps it from finding the OOT source.
I know this is probably basic makefile stuff but it's not basic to
me.
I'm just an FPGA guy.
Thanks,
Mike
