Jonathon and Martin,

I am using your off the shelf xml and noc_block_addsub.v file

When I uhd_usrp_probe --init-only the addsub .bit and .xml file on the E310, I get the following error:

-- Port 64: Found NoC-Block with ID ADD0000000000000.
-- base_path = "/usr/share/uhd/rfnoc"
-- Reading XML file: /usr/share/uhd/rfnoc/blocks/addsub.xml
Error: AssertionError: _send_entries_in_use.at(which_stream) <= H2S_NUM_CMDS
  in uhd::transport::zero_copy_if::sptr e300_fifo_interface_impl::_make_xport(size_t, const uhd::transport::zero_copy_xport_params&, bool)
