Yes, I followed the RFNoC:Getting started guide to install the rfnoc-devel branch and the gr-ettus OOT module. I forgot to mention that in my first attempt to make the fpga image I had the next error:
ERROR: [Synth 8-448] named port connection 's_axis_phase_tlast' does not exist for instance 'cfo_corrector' of module 'cordic_rotator' [/home/sheko/uhd/fpga-src/usrp3/lib/rfnoc/schmidl_cox.v:163]
I removed that port in the schmidl_cox.v file and then it was possible to make the image with the schmidl_cox block.

Are you using the rfnoc-ofdm branches for uhd and gr-ettus?

I'm learning to use RFNoC to implement an OFDM receiver on a E310. The original FPGA image had just 3 RFNoC blocks: FIFO, Window and FFT, so I made a new image removing the window and the FFT blocks and replacing them for a schmidl_cox block. When I run my application with the new image I get the next error:
File "/usr/local/lib/python2.7/site-packages/ettus/ettus_swig.py", line 3002, in set_argreturn _ettus_swig.rfnoc_generic_sptr_set_arg(self, *args)
RuntimeError: LookupError: Path not found in tree: /mboards/0/xbar/SchmidlCox_0/args/0/offset/value
Has anyone run into the same problem?
I'm using UHD_003.010.rfnoc-314-gf773e72b
