I have installed device driver for Altera USB-Blaster. Windows 7 device manager is showing "Altera USB-Blaster" in USB devices but the device is not shown in Tools->Programmer. I have added the device (10M40DCF484) manually using Add Device option. But when I open the SignalTap II Logic Analyzer, I get "No device is selected" in JTAG Chain Configuration. Scan Chain option does not do any action (as seen in the scanned image).Thank you very much for your help.
Hi Zubair,1. Have you turned on the hardware/ development Board?
Thanks sstrell and Anand for your replies. None of the suggested items worked. I have found the cause of this issue to be a conflict between Altera USB Blaster device driver and another USB to JTAG device driver from TI board that I am using to interface with the DE-10 Lite board. Apparently both use FTDI chip. Fortunately, the TI board I am using also supports a second JTAG interface via Blackhawk v2 System Trace debugger that does not conflict with the Altera device driver.Zubair
