Can I use your photo (with credit obviously)? I would like to post it to the RPi forum, to G+ and to my blog! Please do mention it, the more people using it the better as far as I’m concerned! You cannot use.bit files because I wanted to keep it vendor-neutral (FPGALink supports Altera as well as Xilinx FPGAs). I seem to remember the.bit programming algorithm is slightly different for different FPGA families (i.e Spartan3 slightly different from Spartan6, slightly different from Virtex etc) so it would be a lot of extra maintainance for no real gain. Also there are several other features on the TODO list that I think are higher priority.

To be honest I just use emacs for editing VHDL/Verilog anyway and a Makefile for building, so it makes little difference that there’s a two-second.bit ->.xsvf step at the end of the build process: Of course you could continue to edit the VHDL with ISE, but there are far better HDL editors out there IMHO. I’m not sure what the problem is. Which version of fedora are you using? Also is it the 32-bit edition or 64-bit? Did you download the corresponding version of ISE? Anyways, on my setup, I use Fedora 17 64-bit. For other reasons, I have both 32-bit and 64-bit versions of glibc installed.

In case you are using a 64-bit OS, could you see if installing 32-bit glibc works? Beyond that I don’t know what could be wrong. My knowledge of Linux administration is very minimal. You might have better luck at the Xilinx forums. Hi Zain, Ashwith is almost certainly right about the glibc version, but if you have time to do a little bit of investigation before upgrading to Fedora 17, it would be interesting to see what is actually doing this double-free.

If you do this: grep xst *.cmd_log you should see the actual xst command-line that was run. It will be of the form “xst “. If you run this command-line on its own, does it fail in the same way? You will have to source the settings64.sh script first to setup the environment (Ashwith’s startise script does it inline, but you have to source it directly in your interactive shell).

If you run it in the debugger (you may have to install it with “sudo yum install gdb”): gdb xst run where what do you get? The output of LD_PRELOAD=/libdpcomm.so.2 impact: ERROR: ld.so: object ‘/libdpcomm.so.2’ from LD_PRELOAD cannot be preloaded: ignored.

Hi all, I’m trying to run Xilinx on Fedora.But Impact crashing every time after selecting”configure devices using Boundary-scan(JTAG)”. I am using Xilinx ISE 13.4 on fedora 14.
