Linux USB JTAG Cable Driver for Xilinx Impact

I've read much on this topic elsewhere, but I'm confused on some things, no t to mention some of what I've read is out of date w.r.t. s/w versions, etc . I've been frustrated on a previous attempt to get things going, but am no w starting with a fresh OS installation and hope to resolve compatibility i ssues up front.



So, I'm running Ubuntu 14.04 and have downloaded but not yet installed Xili nx LabTools 14.7. I also have the infamous usb-driver-HEAD.tgz from

formatting link
but have not yet installed it.



First, my OS is 64-bit. In spite of that, do I need to install the 32-bit v ersion of LabTools to be compatible with the usb-driver? From what I've rea d, it doesn't sound as though there is a 64-bit version of the driver. Is t hat true?



I'm not sure what runs with what, but need to find out what to do to get th is running.



Would be nice to find a "current" list of installation instructions...



Thanks, Ron

I went through FITS trying to get the old Parallel Cable III to work on

64 bit OS, and finally gave up. I bought a Chinese (clone??) USB cable on eBay, and it worked right away on the 64-bit OS. I'm running Ubuntu 12.04 and the full Xilinx iSE suite. (I think that is 14.04, will check on that.) I think the Digilent pod also works on 64-bit when you install their driver.

this running.

I have found recently that I didn't need to install that USB driver anymore . You should only have to copy the firmware .hex files to the correct place (usually from your Xilinx installation /bin/lin to /usr/share or wherever you choose to have them in your .rules file) and install xusbdfw.rules to / etc/udev/rules.d and restart udev. The syntax and capitalization sometimes need minor adjustments depending which Linux distro you are using. It's bee n a while since I messed with this but at some point along the line I reali zed this and stopped grabbing and building that USB driver from source.
