[Xc3sprog-users] Xilinx Spartan-3A-DSP SPI programming issues

[Tomek C. <tom...@gm...>]

Hello!

Thank you Uwe for xc3sprog and thank you Wojciech for making it
possible on FreeBSD! This is great alternative for while iMPACT and
messy Xilinx USB drivers, although I have FT2232 and Xilinx USB
cables, I am using Xilinx XPC cable to flash my device with some
automation script added :-)

I am able to upload bitstream into FPGA, but I cannot program SPI
memory with success :-( There are errors during the flash process in
random intervals, maybe some buffer is not fast enough, is it possible
to slow down the JTAG clock? I am usin replaced Flash chip that is
supported by iMPACT - ST 25P64. Please advise.

Maybe someone will like the automation script that flashes the Xilinx
cable and then uploads bitfile directly into FPGA or into SPI based on
commandline parameter, so I put initial version below:


#!/bin/sh
# Xilinx FPGA bitfile upload automation script using fxload and xc3sprog.
# (C) 20110826 Tomasz Boleslaw CEDRO (http://www.tomek.cedro.info)

CABLEFW=xusb_emb.hex
VID=0x03fd
PID=0x0007
ALTVID=0x03fd
ALTPID=0x0008
DELAY=10
FXLOAD=`whereis -bq fxload`
XC3SPROG=`whereis -bq xc3sprog`

if [ ! $FXLOAD ]; then echo "You need to install 'fxload' port
first..."; exit 1; fi
if [ ! $XC3SPROG ]; then echo "You need to install 'xc3sprog' port
first..."; exit 1; fi
if [ ! $1 ]; then echo "Usage: script <bitfile> [spi]"; exit 1; fi

echo "Flashing Xilinx Cable Firmware (you may need to set it up first)..."
# First try the cable VID/PID with no firmware.
echo "Flashing blank cable..."
fxload -D vid=$VID,pid=$PID -t fx2 -s xusbdfwu.hex -I $CABLEFW
# Then if necessary try reprogramming existing xilinx cable firmware.
if [ $? -ne 0 ]; then
 echo "Trying to reflash existing xilinx cable firmware..."
 fxload -D vid=$ALTVID,pid=$ALTPID -t fx2 -s xusbdfwu.hex -I $CABLEFW
fi

if [ $? -eq 0 ]; then
 echo "Waiting for jtag interface firmware to settle..."
 sleep $DELAY
 if [ "$2" = "spi" ]; then
  echo "Uploading bitfile into SPI Flash (using provided bscan_spi.bit)..."
  xc3sprog -v -c xpc bscan_spi.bit
  xc3sprog -v -c xpc -I $1
 else
  xc3sprog -c xpc $1
 fi
else
 echo "Flashing Xilinx JTAG Cable failed, exiting..."
 exit 0
fi
