Hi,


According to the error message, there is signal integrity issue for the JTAG Chain. You need to check the hardware design of board.

1. check board schematic to see if there is design problem ( too many devices in the chain without buffer? )

2. Is there any non-Altera device in JTAG chain?

3. Measure JTAG signals by scope to see if there is extra components needed (resistors, capacitors to refine the signal)


Also which Rev of the USB Blaster are you using?


Regards.

Nurina
