JTAG & AS configuration

I can't access via JTAG to others Xilinx FPGA with my probe. Just JTAG detection chain is OK, access to specific FPGA isn't functionning.

All FPGA are on daugther card (one by card), and if I swap the Altera one by a Xilinx one, it's OK (4 x Xilinx in chain). And the Altera one is functionning alone. I can't test severals Altera in same chain because I got only one.

It seems not possible to mix device in same chain in this configuration.

But I would like a confirmation by an expert, maybe there is a solution ?
