I was trying to generate bitstream of my project with ISE (most recent
one 11.4 i think), but no S33 is on the list - Xilinx sux ass in this
matter - I have chosen M25P64 as a replacement from Numonyx, then
generated SVF file and then played that SVF file with UrJTAG. Loading
file into Flash takes a long time and fails. Uploading bitstream
directly into FPGA works fine, and project works until power is on.

I am wondering if the prom file is wrong, or programming the flash
fails. I think that there is no communication with flash, as its
content remains after playing SVF containing "erase-write-verify"
cycle... so I am lookins some other tools to program that S33 memory,
or BPI memory instead :-) I could use my JTAG adapter as ISP
programmer directly on the Flash Chip, but using FPGA-JTAG seems more
versatile, especialy if no SPI pinout is available on the PCB... Maybe
the core uploaded into FPGA for programming the flash use some
different programming algorithm, but as I have seen on the M25P64
document page thet are almost compatibile, except the mass/block erase
available on S33.

Im using FT2232 and FT2232H based cables - none of them was detected
on the binary for win32. Are they supported off the box or I must
recompile?
Has anyone managed to run xc3sprogs on FreeBSD?

Best regards,
