USRP X410, runtime error: Graph edge list is empty for tx channel 0

[ni_hj]

Hi,

I have a new Ettus X410 USRP. I updated it successfully step by step based on:

Ettus USRP X410 Getting Started Guide - NI

then when in the LabVIEW I run example "niUSRP EX Tx Continuous Async.vi" as guide says, I receive this error:

niUSRP Configure Signal.vi<ERR> A runtime or configuration error occurred.

Code: 1359

Details: RuntimeError: Graph edge list is empty for tx cannel 0.

also, I see at the error out display this code: -1074118627

I have the same error when I run the RX example "niUSRP EX Rx Continuous Async.vi".

BTW, I can run uhd_find_devices and uhd_usrp_probe command successfully.

I connect USRP directly to my laptop (I set static IP address for both USRP and my laptop, through editing /data/network/eth0.network file), and can ping USRP.

I have antenna on TX/RX0 and RX1 of first channel in the left side of USRP.

for Device name I enter the USRP IP address.

for Active antenna, I enter the TX/RX0 and RX1, for TX and RX examples, respectively.

I am using LabVIEW version 2022 Q3 (64bit) 22.3.1f8 and usrp_x4xx_fs_v4.3.0.0.mender

Would you please help?

If you follow the guides and still have this error, do this to solve it:

uhd_image_loader --args type=x4xx,addr=127.0.0.1,fpga=X4_200
