Limitations, Known Issues, and FAQs


  1. Support for SVF Format discontinued. Use an earlier release of SDK for SVF support.
  2. Support for 6 Series and below devices discontinued. Use an earlier release of SDK for support of 6 Series and below devices.


  1. While Initializing the bitstream with an ELF file, SDK uses bootloop
  2. How can I set the register display format so that it defaults to "Hexadecimal"?
  3. Can I debug more than one application at the same time?
  4. I have a large ELF application file to debug, and SDK seems to time out when I am downloading the ELF file. How can I increase the time-out period?
  5. I have my board connected on one machine, and I would like to debug my application using SDK running on another machine. How do I set up the Launch Configuration to perform this remote debug operation?
  6. I want to debug an ELF file using SDK without creating a C/C++ Project. How do I do that?
  7. During Debugging (or Running) the application, I would like to download my data files along with my application's ELF file. How do I do this?
  8. How do I specify the Reset options to be used when a Debug (or Run) session is launched?
  9. In which scenario should I use Xilinx System Debugger or Xilinx C/C++ Debugger (XMD+GDB)?
  10. How can I tell Xilinx System debugger to start at program entry?
  11. Debug after re-launch does not stop on breakpoints.
  12. Cannot set more than 5 breakpoints/watchpoints for ARM targets
  13. Launching hw_server gives a "missing FTD2XX.dll" error message.

Known Issues

  1. MSS Viewer does not refresh automatically
  2. Renaming hardware platforms causes compilation errors
  3. Restore defaults in C/C++ Build Settings causes settings to be lost
  4. Operations on XMD console can confuse the internal state of SDK
  5. When SDK launches, it does not display the correct menus, the correct icons, or the C/C++ Perspective
  6. Kintex-7 FPGA KC705 evaluation board with older device revisions require a workaround during debugging to compensate for the memory controller calibration time
  7. SDK internal state gets out of sync with actual target status if Zynq board is switched off during execution of an application
  8. Debug System Reset does not work on a 2.0. Zc706 board that has the 2.0 silicon
  9. SDK Hangs After Design Changes in Block Design and Export Hardware (Design with User IP)
