Yealink is a gloMissing Xilica “Download Project Backup File”. There are two different scenarios that will cause this: – When you push the file to the unit, you are prompted if you want to save the project or “cancel”. On first glance it’s easy to think that the “save” is to your PC when it actually saves the file to the unit itself for recovery. – If you have more than one QR1 in a project, the “Master” unit is the one that contains the backup file. Xilica elects the master unit as the one who arbitrarily holds the Project Scheduler. One option is to right-click on the unit and “Export Device Design to File”. You would then still have to create a new project but will have the option to “import” this file. It won’t have your Project controller configuration, etc. but will save you from having to start over for the actual DSP file.
