Q: Why does the readback from target fails even though the download is successful and there is audio playback?
A: When USBi is used as the communication device, the “FirmwareVersion” property of the USBi in SigmaStudio+ project should be set based on the version of the hardware. “FirmwareVersion” should be set as “v1.5” when the version of the USBi board is 1.5 or later and “Pre v1.5” should be used for 1.4 or earlier versions. This property can be updated using the SigmaStudio+ Property Window. Failure to set the proper version number can affect the readback operation.
