Description
This error may occur in the Quartus® II software version 4.2 or 4.2 SP1 when you generate a JAM or JAM Byte-Code File (.jbc) file for a MAX® II device with a user-defined (non-Altera®) device in the JTAG chain.
This problem is fixed beginning with the Quartus II software version 5.0.
If your project requires that you use version 4.2 SP1, use mySupport to request patch 1.06 to fix this problem.
