Xilinx Vivado 2014.2 on Xubuntu 14.04

Lately I’ve been playing with the Xilinx Zynq 7000 FPGA/ARM platform, using the Digilent Zybo development board. The ability to design some hardware and then write a device driver for it (in my case for Linux) without excessive faff is great! (And just so that you don’t think I’m a shill for Xilinx, I’ve spent most of my FPGA time the last two years n Altera-land.)

Of course, software is involved so a bit of screwing around remains. Here are some brief notes.

  1. I installed Vivado as root, including “cable drivers” (which seems to amount to adding some hotplug stuff). Then I blew away /opt/Xilinx and reinstalled everything (minus drivers) as myself. Everything seems to work.
  2. I have Xubuntu in a VM and there appears to be a race condition or locking problem if the project is located in a directory on hgfs. Vivado was unable to launch runs, meaning that the generated runme.sh scripts had to be started manually. Yuck. Moving the project to the VM’s disk fixed this.
  3. I run 64-bit but the ARM GCC is 32-bit! It seems that by default the compatibility libraries are missing, so SDK blew up because most binaries couldn’t be launched. Installing the package libc6:i386 (and the dependencies it dragged along) seem to have fixed this.
