I have 3 jtag ice modules and all three failed to upgrade, after I downloaded Atmel Studio Version 6.2.1563 Service Pack 2. I am running Win 7 (64-bit). I tried the suggestion of running from the command prompt atfw.exe3 -t jtagice3 -a "C:\Program Files (x86)\Atmel\Atmel Studio 6.2\tools\JTAGICE3\jtagice3_fw.zip", and got the following response: Generic Error thrown during firmware upgrade. USB driver initialization failed: No valid license (0x20000009). Checked my Windriver under Jungo and appears to be up-to-date. What should I do?
