    Connect the device to Fusion Digital Power Designer via USB-to-GPIO adapter. The GUI will recognize the device and extract configuration. Under File menu you can save a project file, and import the project file to the blank device.

    Hi

    yes, you can export a data flash image file via TI fusion GUI and import the same file to the new blank device via fusion GUI.

    Data Flash file is an image of the device flash. The PMBus host transfers data into UCD90xxx by chuck and thus the communication is relatively fast. There is a checksum included in the Data Flash file. If the data flash content does not match the checksum, UCD90xxx does not execute the configuration and behaves as a blank device. In this way, UCD90xxx is also protected against communication error. The settings transferred by the image file do not take effect until a reset or power cycle is triggered. Fusion GUI can only export Data Flash file from a connected online device. 

    The export is done from File->export..->Data flash file

    Regards
