Honored ContributorFortunately, my inconvenience was solved.
It was my routine to open the Quartus Programmer and directly click the start button after selecting the .sof file after the detection of the USB Blaster. It holds good for the Cyclone III device.But not for the Stratix IV GX A/V Dev Board. Fix: i). For a change i deleted the existing .sof file from the window ii). Clicked the Auto Detect Button to check the jtag chain status. "Was present" iii) Selected the EPM device. iv) Added my project.sof file to the GX device and deleted another instance of the GX device and clicked the Start Button. Bingo!! The .sof file successfully downloaded via Quartus Programmer. Thank you so much Alex and Dave for your patience. Much appreciated! Altera Gurus! :cool:
