I figured it out. The problem was that in noc_block_split_stream.v, rb_stb was
set to 1'b1 in the noc_shell instantiation.
I changed it to ".rb_stb({NUM_OUTPUTS{1'b1}})" and it seems to have build OK.

Subject: [USRP-users] problem with custom E320 FPGA image
I've seen chatter on this around here before (an I think I might have been
involved with it during my failed N310 project a while back), but I haven't
come up with a solution yet.
I have a custom RFNoC bitfile I want to use on the E320. I set things up and
built it with the mods in rfnoc_ce_auto_inst_e320.v to fix the clk like is done
in rfnoc_ce_default_inst_e320.v.
It builds fine and I scp it over to the E320. I then load it up with the
command: uhd_image_loader --args="type=e3xx" --fpga-path="/home/root/e320.bit"
It acts like everything worked fine, but then when I probe it, it errors out:

I thought that this error was due to the clocks in the inst file being wrong,
but I've made that mod already. Any other thoughts? What is a little weird to
me is that it is complaining about CE_08_Port_A1, but I only have 8 CEs, so I
would have thought my largest one would be CE_07.
