For Cassini technicians using RI8608 Linux NUC , the procedures are the same but may have slightly different look and feel or use OS specific path names. The Cassini application runs inside ArcaOS desktop container (Oracle VirtualBox) that connects via DbManager and rTalk to control the tester via a USB RIFL Master interface attached to the Cassini Infrastructure. All Guru apps run natively in Linux OS except for the Cassini application, which runs in the ArcaOS desktop VirtualBox container (VM). Those familiar with the Cassini Virtual Workstation may notice that the ArcaOS desktop has icons and features removed that are now provided by the Linux host OS. Additional Linux native application and utilities are also available and should be used, like when viewing PDF files or accessing the desktop remotely.
At login, the Linux EPC will automatically launch the Guru Server client, Db Manager along with the rTalk and the ArcaOS virtual desktop. The Short Cuts menu will only activate if the ArcaOS container is active and Db Manager is running. The rTalk window and DbManager apps MUST not be closed, since the Cassini app connects with the hardware through those applications. All critical apps will automatically restart after being closed.
Tips using Linux OS Desktop (XFCE)
- Resize windows with ALT+Right Mouse Button drag, since clicking precisely on the window edges is difficult. (See Figure 1)
- When using Cassini in Container (VM), hold the WIN+ALT keys down to edit Limit table values or modify Test Exec table settings when the hint still shows "ALT+Click".
- VNC can be configured to connect to the currently running desktop session using XVNC. To use Remote Desktop (RDP), the local user must first Log Out of the Linux desktop since ONLY one user session is allowed to be active at a time and the activity is not displayed for local users.
- xUbuntu 24.04 LTS usability guides available on the internet are a great resource for learning.
- Use SCP protocol instead of FTP to transfer files to and from the EPC. WinSCP is a popular windows application that can be used.
Notable Similarities:
- Launch Cassini from the Short Cuts menu and Execs from the User Apps menu. Cassini will appear within the ArcaOS desktop container window using VirtualBox.
Log On > Engineer/password > Short Cuts > [Latest Dev] or User Apps > [DUT Exec] - Development with the Cassini application is familiar, however the Worksheet displays as a separate, native window in the Linux OS.
Key Differences:
- Cassini Worksheet opens behind the ArcaOS (VM) desktop a new Linux window visible by clicking on the Worksheet app from the task bar or Guru.
- Files saved to the Cassini Drive-D (D:/) are in ~/Cassini-D folder. Exporting CSV Limit table or Diagnosics Results saved to D:\shared\sample.txt be available ~/Cassini-D/shared/sample.txt path in Linux OS apps or file transfer tools like SCP.
- RED Cassini message window appears if RIFL connection is lost through the rTalk application. Save any changes and restart the Linux OS to quickly recover.
- Multiple displays can be used to extend the available workspace.
