Installation and Licensing

[xilinx20@snowdon.id.au]

Hi all, 

I thought I would write in after the last few hours of mucking around trying to get impact to run after upgrading my machine to Ubuntu 11.10 (I realise it's not supported, but there will be plenty of people like me who want to run an up to date OS and applications). 

I was having problems with impact crashing whenever it went to access the USB cable. Chipscope analyzer has similar problems. 

It turned out that the Digilent plugin is what causes the crash. It happens just after libusb-1.0 is loaded. All you need to do to get things working is to remove the plugin. In my case that involved:  

mv /opt/Xilinx/13.2/ISE_DS/ISE/lib/lin64/plugins/Digilent/ tmp/

I hope that this saves someone else the few hours it took me (which it shouldn't have, in hindsight). 

Dave.

Thanks for that.

Indeed, solved the problem for me too on Ubuntu 11.10.

My problem now is how should I deal with my Atlys board ? I still need the Digilent

plugin to work ?

Any advise ?

I solved the problem.

My mistake was that I first installed Design Suite on windows + Atlys card. Then I copied the Digilent plugin files 

directly from the Windows installation to the Ubuntu installation.

You should ensure that you use the Digilent plugin for linux and not for Windows.

http://www.digilentinc.com/Products/Detail.cfm?NavPath=2,66,768&Prod=DIGILENT-PLUGIN

Summary: Ubuntu 11.10, Design Suite 13.3, Atlys card (Spartan 6) and cable driver all work fine now.

I also ran into this problem and wasted a bunch of time trying to solve it under Ubuntu 11.04 and 11.10.  Dave's solution will work if impact is crashing and you see a log message about libdpcomm when you run demsg:

_impact4[22438]: segfault at 0 ip 00007fcf6d49f5f8 sp 00007fff5e0c87f0 error 4 in libdpcomm.so.2.6.4[7fcf6d493000+31000]

Like you mentioned, I hope this info helps others find this thread before wasting too much time.

Hello. 

I have the same problem here with version 13.2 and 13.1, which install the plugin by default...

And this fixed it:

ricardo@newpili:/opt/xilinx/13.1/ISE_DS$ mkdir trash; mv ISE/lib/lin64/plugins/Digilent/libCseDigilent trash/

And this is the backtrack, in case someone at xilinx wants to fix it....

thx for the info :smileyhappy:

[lotussx]

Thanks for your debugging work. I am filing an internal CR on this issue.

[tharion]

Hello,

I am using a Spartan6-LX9 Microboard from Avnet and had the same problem with Impact. I didn't want to use the Platform cable because the Microboard is small enough to carry everywhere and I didn't want to take the programmer along with me.

Since the Digilent Tools themselves work I searched further and found that apparently the dynamic linking of the libdpcomm.so.2 library from Digilent creates the segfault.

I found one solution to this problem, which appears to work on several installations: Setting the LD_PRELOAD environment variable to

LD_PRELOAD=/usr/local/lib64/digilent/adept/libdpcomm.so.2

For 32 bit systems the library can be found in the corresponding folder. This forces the libdpcomm library to be loaded at startup of the program. The needed memory address can then be found by Impact.

Removing the  Digilent_Plugin also stopped Impact from doing a segmentation fautl, but I needed the Digilent Plugin. This worked for me and at least one other user with a Nexys2 board.

I hope it helps to fix the problem in future releases

Cheers

Tobias

Hi,

I forgot to mention:

The problem occured with a fresh install of the Digilent Plugin, the Adept runtime from Digilent and ISE 13.4.

Cheers

Tobias

[gronenberg]

I encountered a similar (or the same?) problem using WebPack ISE 13.4 64 bit on openSUSE 11.4 64 bit:

Impact just closed itself when loading a file and gdb backtrace hinted in the same direction regarding the Digilent plugin.

Moving it out of the way eliminated the problem. I then installed the current plugin from Digilent (2.1.7 instead of 2.1.5 delivered as part of ISE 13.4) and the problem reoccured. As gdb output also pointed to Adept, I installed the current version from Digilent (2.9.9 instead of 2.7.4 delivered as part of ISE 13.4) and the problem disappeared.

It seems that, at least on my setup, the current versions of the Digilent plugin (2.1.7) and adept runtime (2.9.9) solve this problem.

Best regard, Arnd (DJ9PZ / AB2QP)
