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: root@ni-e320-318B090:~# uhd_usrp_probe [INFO] [UHD] linux; GNU C++ version 7.3.0; Boost_106600; UHD_3.14.1.HEAD-0-g5491b80e [INFO] [MPMD] Initializing 1 device(s) in parallel with args: mgmt_addr=127.0.0.1,type=e3xx,product=e320,serial=318B090,claimed=False [INFO] [0/DmaFIFO_0] Initializing block control (NOC ID: 0xF1F0D00000000000) [INFO] [MPM.PeriphManager] init() called with device args `mgmt_addr=127.0.0.1,product=e320'.

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.
