Red circle with backslash 
The major version number of Xilica Designer is different from the firmware in the device. This will cause communication breakdown and you must update device firmware before it will work properly with this version of Xilica Designer.
 

Yellow triangle with exclamation mark
The detected device has a lower minor version as compared to the recommend minor version in the Xilica Designer software. In this situation, some new features provided in Xilica Designer (i.e. new DSP modules) will not function in the device. We recommend upgrading the device firmware.

Xilica firmware files use a numbering scheme of X.Y.Z (for example, 4.1.0).

X denotes a major version which means a significant modification of compatibility or communication protocol has been made. If Xilica Designer and the device(s) have different major versions, they will not work together and unexpected behavior will occur. 

Y denotes a minor version which indicating functionality changes, however the communication protocol will remain compatible. New features will not function properly if minor versions are mismatched. 

Z is the build number and indicates minor patch updates and/or bug fixes.

The device clock is not synchronized
Xilica Designer software provides a function to allow you to synchronize your host computer clock to the device real-time clock. In Network View, a clock icon will be displayed in the lower left of the device block. When online, the device clock will check and confirm that it is the same as your host computer. If the clock is correct, it will display a normal clock icon. If the clock is different from your host computer, the clock will display a question mark on top of the icon. This clock pertains to time of day and is not involved in any kind of digital audio clocking.
To sync one device: right-click the device block > Synchronize Device clock. 
Sync all devices choose Sync clock to all devices in Network View.
After the clock is synchronized, the device will automatically reboot.

No Data

The processor currently contains no programming / project file. If the same error message persists even after loading a design to the device, please restart the device and reboot the software. 

IP Issue / TCP Error
There is an Ethernet connection issue with the device. When a device is detected, a TCP connection is established from Xilica Designer to the device. If it fails to obtain the device information after a one minute timeout period, this TCP error message will be displayed.
If there was a temporary network issue that caused the TCP message to drop, it may take up to one minute before it can retry and recover. However, if the network issue persists, the TCP Error icon will be displayed.

Troubleshooting an IP Issue / TCP Error
1. Disable the firewall on your host computer and see if it resolves the problem. 
2. Disable any antivirus software running on your host computer.
3. Disable WIFI on host computer if directly connected to AV network. 
4. Check for duplicate IP addresses. Unplug the processor's Ethernet port from the network, then ping its IP address. If you receive a reply, then there is a conflicting device somewhere else on the network with the same IP address. 
5. Right-click the device block > Remote Reset Device to reboot the hardware.
6. In Xilica Designer's Network View, right-click the device block > Device Setup > Networktab > Connectivity Test > TCP Test.
7. Check the IP address range of your host computer to see whether it is consistent with your device IP range.
8. At the top left of Network View, it will display the IP address of your host computer. Notice that there are multiple IP addresses. This is because the computer has multiple network interfaces (such as, WIFI, Bluetooth connection, etc.).
9. Make sure the device IP address is within the same subnet of your host computer (or use a router to route the network traffic to the appropriate subnet using DHCP).
10. We also recommend keeping your host computer network interface to the minimum. If you can disable some of the unused network interfaces, that will reduce the confusion of network traffic. If you're hardwired, disable WIFI.
11. Direct connect to isolate the network.
