Hi, I am new to configurating multiple devices through JTAG. Does anyone know if it is possible to configure multiple devices (Xilinx Spartan FPGA and CPLD) in a daisy chain through JTAG. The problem I face is that the the devices concerned have different Vcc(s). The former is 5V and the latter is a 3.3V device. Is it only possible to configure them separately through JTAG. Thank you.

A good help is on the xilinx site. xilinx.com --> Support --> Problem Solvers --> JTAG Problem Solvers From there, look for relevant info. johnong99@hotmail.com (john ong) wrote in message news:<a11135b4.0404192350.107f4a14@posting.google.com>...> Hi, > I am new to configurating multiple devices through JTAG.
