RF Data Converter Evaluation User Interface stuck in "Update Display"

Jump to solution

Hello, 

I've been using v2019.2 RF Data Converter Evaluation User Interface with ZCU111 for few months. After some hiatus, I tried to run it today. The UI gets stuck on startup at "Update Display..." stage. Task manager says it is waiting to finish network i/o(?). I'm running it on Windows 10 64 bit:

Hi @fbalakirev

I think you are correct v1.5 or earlier doesn't support lab view 2020 runtime environment.

V1.6 of the analyzer will support this labview runtime in this case 1 6 Eval gui is not dedicated to the zcu111.

The following appears on ZCU111 console after GUI in launched:

Accepted data connection
Accepted command connection
datapath_t: waiting for lock
datapath_t: acquired lock
disconnect: waiting for lock
datapath_t:Releasing lock
disconnect: acquired lock
disconnect:Releasing lock
Closed data and command sockets
Accepted data connection
Accepted command connection
datapath_t: waiting for lock
datapath_t: acquired lock
datapath_t:Releasing lock

The GUI loading screen then hangs, while Windows Task Manager shows ~12% constant CPU load by GUI task.

The GUI also hangs up if ZCU111 not connected. In the past it gave appropriate error dialog.

I have a hunch and installed the GUI on two other PCs - one with National Instruments software (i.e. LabVIEW, VISA, etc.) updated to v. 2019 and the other with updates to 2020. The GUI starts up fine on the PC with 2019 version of  NI software, but  hangs up just the same on  PC updated to 2020 NI software.

Based on my experience with LabVIEW and NI in general, I believe the RF Data Converter Evaluation User Interface application is incompatible with current NI software and drivers and needs to be re-compiled by MESULOG.

By the way, my own LabVIEW 2020 application works with ZCU111 rftool just fine using same protocol as official GUI
