[Xc3sprog-users] xc3sprog and Digilent "atlys" board?

[Sidney C. <si...@ji...>]

Hello,

I am currently considering buying a Digilent Atlys board
(http://www.digilentinc.com/Products/Detail.cfm?NavPath=2,400,836&Prod=ATLYS),
and I am wondering if it is possible to program its Spartan-6 using
xc3sprog.

The Digilent product page suggests that I should use either the
Digilent-provided Adept software, or Xilinx' impact software with some
kind of Digilent driver. However, I would very much prefer using an
open-source programming tool.

Kind regards,

  Sidney

Digilent uses a FT2232H, so probably th jtaghs1 cable could work. The
cablelist.txt jtaghs1 however is contributed and I never tested it myself.

If you buy the card and test, please let me know the results.

I just got an Atlys board. I can confirm that xc3sprog programs the
Spartan-6 FPGA on the Atlys board without any issues if a separate JTAG
cable is used.

The Atlys board also has an on-board JTAG-USB programmer based on a
Cypress FX2, but it uses a proprietary USB protocol and therefore does
not work with xc3sprog.

Programming the SPI flash chip on the Atlys board needed some work.
xc3sprog SVN r717 gives the following error message:
  Found Numonyx Device, Device ID 0xba18
  M25P: Unexpected RDID upper Device ID 0xba

I added support for N25Q devices in progalgspiflash.cpp to fix it.
This is now committed in SVN r718 (shout if you disagree).

Of course, a bscan_spi bitfile is needed to access the SPI memory. The
xc3sprog distribution already contains xc6slx45-fg484.bit which appears
to work with the Atlys board. However, the Atlys FPGA is xc6slx45-csg324.
Do you know if it is safe to use bscan_spi files for a different
package, or should I build a separate bitfile for csg324?

Kind regards, Joris.

Did you try the the xpc cable? Perhaps it Digilent uses that cable?

Probably it is the same chip in the  csg324 and  fg484 package. If it works,
it should be safe.

Yes, I tried xpc and fx2 but they don't work.
I think their FX2 firmware is a Digilent-specific design.

It may be possible to adapt the XGUFF firmware to run on the FX2
chip on the Atlys board, but it is low on my list.

Ok, that makes sense.

Thanks, Joris.
