Hello all,
I'm currently tinkering with synchronizing two X310 usrps (NI-2955 to be exact), connected to my laptop through Ethernet switch. It's worth noting, that in my application I use NI-USRP API, not USRP RIO IDL. Everything was going good at first and I could receive data, but now during the application startup I get the following error:
Error -1074118627 occured at niUSRP Open Rx Session.vi
Possible reason(s):
A runtime or configuration error occurred.
Code: 312
Details: EnvironmentError: IO Error: x300 fw communication failure #3
EnvironmentError: IOError: x300 fw peek32 - reply timed out
I tried switching to different computer to see if the issue would persist. Following error popped up, when VI tried to read device model information through Property node:
Error -1074118627 occured at Property node(arg 2) in synchro demo.vi
Possible reason(s):
A runtime or configuration error occurred.
Code: 312
Details: EnvironmentError: IO Error: 0/Radio_0 user_reg_read64() failed:
EnvironmentError: IOError: [0/Radio_0] sr_read64() failed:
EnvironmentError: IOError: Block ctrl (CE_01_Port_40) no response packet - AssertionError: bool(buff) in unsigned __int64__thiscall ctrl_iface_impl::wait_for_ack(const bool) at P:/Measurements/FlexRIO/SWCode/usrp/niuhd2/trunk/18.0/objects/uhdrepo/host/lib/rfnoc/ctrl_iface.cpp:204
Usually I would blame the switch in such case, but this exact setup was working correctly just a few days back. I can successfully ping both devices and acquisition works correctly, when only one device is running, so SFP+ to RJ45 adapters and cables should be ok. I power-cycled everything and even reuploaded FPGA images to both USRPs, but to no avail.
It's the first time I encoutered those erros, so I would be grateful to anyone who helped me decipher them!
Cheers,
Piotr
