[Xc3sprog-users] xc3sprog didn't find a device in the multiple devices chain

[Luis A. G. <gua...@gm...>]

Hi All,
I have a S3Board (by Digilent)[0]. The board has a FPGA (XC3S200) and
a PROM (XCF02S). This devices are connected a JTAG chain (JTAG[TDI]
--> FPGA --> PROM --> JTAG[TDO]).

I use the OOCDLink-s[1] board which is a FT2232D based JTAG interface.

The problem is when I run xc3sprog it didn't find the
FPGA(0x01414093). It found only the PROM(0x01414093) memory. In fact,
xc3sprog detect other unknown device but sure it's wrong value.

Using Libftdi,
Probably a broken Atmel device in your chain!
No succeeding device can be identified
Cannot find device having IDCODE=f7fffff Revision P
JTAG loc.:   0  IDCODE: 0xff7fffff  not found in 'built-in device list'.
JTAG loc.:   1  IDCODE: 0x01414093  Desc:
XCF02S Rev: A  IR length:  8


I probed to connect the JTAG chain with the  Cable USB II (Xilinx)
and it works! (I can program the FPGA and PROM with the iMPACT
software).

I used xc3sprog with a CPLD (XC9572XL) and I didn't have any problem
in detected it. But I don't know how solved the problem with multiple
devices.

Anybody used xc3sprog with a multiple  Xilinx devices (FPGA,PROM,CPLD)?

Thanks in advance!

Luis

P.S.: I am developing a Reconfigurable Hardware Platform (hardware and
software development). The PHR (acronym in spanish "Plataforma de
Hardware Reconfigurable") is a free/open project. It's a board with a
FPGA with a PROM memory and several devices connected to IO ports of
the FPGA. The hardware design has a GPL licence and I want used a free
software to program the devices (FPGA and PROM).
The project is hosted on opencores.org server. For more informations
you can visit http://opencores.org/project,phr
