we are developping a custom board, in which we have 2x XE216-512-TQ128-I20 and then a Spartan6 FPGA.
Impact tool (Xilinx FPGA programming tool) works smoothly discovering the whole chain, which is composed by 2 unknown devices (XMOS) and the FPGA that could properly be programmed.
Unfortunately the same doesn't happen with the xTag3. We found no way to make xTag3 to recognize any of the connected devices.

It's necessary to let the tool know the FPGA presence and how to bypass it. It seems it doesn't happening automatically.
Digging in the forum there are some posts about this matter, but without any useful answer. It's seems that something can be done by customizing the .xn file, but documentation doesn't really help in doing this.
Anyone had had success with the same problem?
