[UrJTAG-dev] Patch - UrJTAG and Xilinx Kintex7 - xc7k325t-ffg676

[Christoffer Kjølbæk]

Hi,

The attached patch will get the Xilinx Kintex7 - xc7k325t-ffg676
working with UrJTAG.

I had a few problems getting the Xilinx BSDL to work with bsdl2jtag,
and had to remove some of the content - see
http://permalink.gmane.org/gmane.comp.embedded.jtag.urjtag.devel/1327

I have only tested that I can find the FPGA and use the SVF part of
UrJTAG, which is working.

As the SVF file is about 44MB, UrJTAG was compiled with
CFLAGS += " -DYY_BUF_SIZE=52428800 -DYY_READ_BUF_SIZE=50000000"
to speed up the parsing process as described at
http://comments.gmane.org/gmane.comp.embedded.jtag.urjtag.devel/17

The patch is against
https://urjtag.svn.sourceforge.net/svnroot/urjtag/trunk/urjtag rev
2035

As I have only tested this with some of the functions of UrJTAG I take
no responsibility for the use of the patch, but I have programmed
various Kintex FPGAs without any problems :)

Hi,
I can confirm that after modifying the appropriate BSDL file by removing the
offending sections found by Christoffer and generating the JTAG file that I have
been able to use Urjtag to program a Xilinx Kintex 7 xc7k160t-ffg676 device and
attached SPI flash.

In case anyone else has a similar problem, I suggest to follow Christoffer's
advice above.

Thanks,
Joe

Hi

Is there a step by step document on how to program a xilinx chip + spi flash?
I am using a xc6slx9 + winbond spi flash. but I cannot figure out how to reflash
the spi flash by using urjtag.

Thanks in advance.

Just noticed your post now - I did a little video in case you are still
looking for that answer. See

.

You can script some of it too instead.
