[Discuss-gnuradio] How to solve command timeout error

Dear all,  I have been working on my X310 USRP with gnuradio just fine. But after I have  installed rfnoc modules and reload fpga images , the behavior of the  device becomes unpredictable. It sometimes throws the following error  message even if I run legacy gnuradio applications (or non rfnoc application):    "RuntimeError: EnvironmentError: IOError: Block ctrl (CE_00_Port_30)  no response packet - AssertionError: bool(buff)    in uint64_t ctrl_iface_impl::wait_for_ack(bool)    at /home/haile/prefix/default/src/uhd/host/lib/rfnoc/ctrl_iface.cpp:197"    I have observed that the above error is not thrown in the first run  after I power cycle the device. [1] seems to discuss the issue but the  proposed solution is not clear. It says, check ce_clk/ce_rst are  connected in the rfnoc_ce_auto_inst_<device>.v., etc .. How am I  supposed to check?    Thanks,    [1] https://kb.ettus.com/RFNoC
