"UNKNOWN_NO_JTAG_ID" message showing while auto detect option in FPGA on JTAG mode.

Hello sreekumar.regu.girijakumari,

I have tried in both device and configuration option and Convert programming file options. With these options i could generate for EPC1 and EPC1441 devices.All these options shows Flex 6K cannot be configured with EPC2. I had already gone through a lot documents including this and I could find that Flex 6K wont support EPC2. Actually this is my biggest problem.

The custom board with me is FLEX 6K and EPC2 is configured with it. The .pof file given for this board was configured for EPC2 itself and it is successfully programming to the board. Its tested an verified and its a real time example that EPC2 can work with FLEX6K but don't know how.

Somebody managed to generate it and I was searching for the procedure/configuration change for this.

That's the reason why I removed EPC2 device from the board, so that i can program via JTAG, but this attempt ends with the error "UNKNOWN_NO_JTAG_ID". Any idea about this error also??

Note: I am using USB blaster and the attachment I have given for the JTAG connection, its given for BitBlaster/ByteBlaster. Does it have any impact? Is there any other connection diagram specified to FLEX 6k?

Regards

Roopak
