I could not download my design file into XCM-020 Spartan-6 FPGA board configuration device by indirect programming.
I am using ISE14.2.

We confirmed that ISE14.2 iMPACT tool fails to program to a configuration device indirectly.



We received same question for boards below,



The iMPACT will faile to read IDCODE (with "ffffff") of configuration device after configuring the FPGA with an indirect design file.

ISE14.2, LX150 device. iMPACT failed to read IDCODE.

ISE14.2, LX100 device. There is no problem.

We confirmed that we can download by ISE12.3.
