Does the FTDI get recognised when plugged? Look e.g. with "dmesg".
If it gets recognized, do you have decent access rights on that device? If
xc3sprog recognises the device when running as root, change the udev rules.

And when the device gets recognized and you have access and then connection
still fails, check the connection on the board.

Hope this helps

[Xc3sprog-users] Programming the Digilent Genesys 2 board

[Joe H. <xc3...@su...>]

The Genesys2 has a FT2232H FTDI chip connected to the JTAG ports on the
FPGA, a XC7K325T-2FFG900C. It seems as though all the pieces are there
to enable programming this board with xc3sprog, however I can't quite
get it to work.

Programming with cable type `ftdi` or `jtaghs1` produces the error
message: 

```
Using Libftdi,
No JTAG Chain found
```

Programming with other cable types gets less far, for example the
`jtaghs2` or `ftdijtag` cable types are not even able to find the
device.

```
Could not open FTDI device (using libftdi): device not found
Unable to access FTDI device with either libftdi or FTD2XX
```

What options do I have for debugging this? Perhaps there are tweaks I
can make similar to what was done for the `nexys4` cable type.

Best,
Joe.

Hello Ankit,

are you sure TDI and TDO lines are "connected in parallel" ? This will not
work! You must form a chain, connecting TDO from first device to TDI of
second device.

[Xc3sprog-users] Second port of ft2232, ISF mode and donation

[Frans S. <fra...@gm...>]

Hello,

First of all thanks for the great software! I think this is something
Xilinx schould provide, but a couple of brave guys did it instead.
I would like to report that the Artix 35T works flawlessly both with the
digilent hs2 and the ft2232. I have 3 questions however.
1). I use interface B of the ft2232h for jtag, but i couldn't find the
command line option to select it. Hardcoding the interface in ioftdi.cpp
works, but how do i normally do that?
2). I see that ISF is supported, but where do i find the bitfile that goes
into the fpga? Should it be somewhere in the vivado folder?
3). I would like to do a donation but couldn't find a donate button. Do you
have other ways to send you some money?

Thans and kind regards,

Frans Schreuder

[Xc3sprog-users] Windows compilation

[lyf4 S. <ly...@gm...>]

Hi experts,

I tried compiling the recent version of xc3sprog in windows 8.1

Installed mingw compiler and configured using cmake gui with change to
system path variable. In cmake compiler chosen in Mingw Makefile and
libftdi path is linked. When I tried invoking mingw32-make in the xc3sprog
folder it is throwing error as "system path not found".

Kindly provide  correctness of above steps and how to compile for windows
versions.

No big hassle, if you try it, please feel free to so.

My next step will be to ask the author of the original core, to compile the 
core for the Artix7, because it will be something that project needs anyway: 
a way to update the board without the xilinx toolchain. If he distributes 
the bitstream of the core together with the bitstream of bscan_spi, a link 
to xc3sprog and a small cmd-script / shell-script that'll run the flash 
process (which will be most probably provided by me), it will make life 
easier for everyone involved.

If you can't compile it, I will also ask for permission to commit his 
version of bscan_spi to the xc3sprog project. This way both projects will 
benefit. But that might take a couple of days, because he's on a field trip, 
afaik.

I don't know if my ISE14.6 installation still has the license to compile

It's an Artix-7:

Yes. Writing the bitstream "to the ram" of the FPGA and starting it is working 
perfectly.

As stated, it's an Artix-7. Sorry for forgetting to mention this. Being a 
software developer I know how hard it is to get a good problem report. ;-)
Xilinx part number is: XC7A100T-1CSG324C.
The board is this one: https://reference.digilentinc.com/nexys4-ddr:start

[Xc3sprog-users] Trying to write to SPI of Nexys4

[Sven O. M. <xc3...@sv...>]

Hello,

I'm trying to write to the SPI flash of an Nexys4 board. Uploading and 
running bitstream either via USB or via SD card works fine, but I can't
get it running from flash. As far as I can tell, there's a matching 
"bscan_spi"-code missing.

I'm using the board for the sole purpose of running the MEGA65 core only
(http://mega65.org), so I'm not writing any vhdl-code, and don't have an
IDE for creating FPGAs.

So here are my questions:
- Is my assumption about the missing bscan_spi for the Nexys4 correct?
- Will it work (as in getting it to load bitstream from flash on startup)
   once I've got a working bscan_spi?
- Can I use any of the other bscan_spi already provided?

[Xc3sprog-users] Open question: support for other FPGA families?

[Adrien Prost-B. <adr...@la...>]

Hi,

I have a small Actel Igloo Nano FPGA board and I thought it would be
nice if it could be programmed with xc3sprogs.
http://www.microsemi.com/products/fpga-soc/design-resources/dev
-kits/igloo/igloo-nano-starter-kit

I can see that xc3sprogs is able to program Xilinx devices, but not
only, as some AVR microcontrollers can also be programmed.
So I wondered whether the extensibility of xc3sprogs was enough to
consider porting it to other FPGA families ?

I also know people that would love any kind of support for Altera DE1
board. I can get one of these boards.
http://users.ece.gatech.edu/~hamblen/DE1/

1) Is xc3sprogs extensibility high enough to support other FPGA
families?
2) What amount of work would it require to add this support?
3) Is such work reasonably accessible to newcomers? 
4) Are there other people that would like support for Actel or Altera
boards, or other board families?

Best regards,
Adrien
