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. How can I set the register display format so that it defaults to "Hexadecimal"?
  2. Can I debug more than one application at the same time?
  3. 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?
  4. 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?
  5. I want to debug an ELF file using SDK without creating a C/C++ Project. How do I do that?
  6. 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?
  7. How do I specify the Reset options to be used when a Debug (or Run) session is launched?
  8. In which scenario should I use Xilinx System Debugger or Xilinx C/C++ Debugger (XMD+GDB)?
  9. How can I tell Xilinx System debugger to start at program entry?
  10. Debug after re-launch does not stop on breakpoints.
  11. Cannot set more than 5 breakpoints/watchpoints for ARM targets
  12. Launching hw_server gives a "missing FTD2XX.dll" error message.

Known Issues

  1. While debugging the BSP code, some variable values are displayed as N/A
  2.  Exporting project to GIT server causes problems in BSP/Application Compilation
  3. Projects created in the default location may cause compilation issues
  4.  After installing SDK on Ubuntu machines, toolchain paths are not accessible from SDK
  5. Ucos application project creations fail due to non-availability of pre-compiled libraries and source code
  6. Debugging or running of A53 32-bit application requires board reset
  7. MSS Viewer does not refresh automatically
  8. Renaming hardware platforms causes compilation errors
  9. Restore defaults in C/C++ Build Settings causes settings to be lost
  10. Operations on XMD console can confuse the internal state of SDK
  11. When SDK launches, it does not display the correct menus, the correct icons, or the C/C++ Perspective
  12. After any reset, the debugger hangs when accessing DDR3 memory
  13. SDK internal state gets out of sync with actual target status if Zynq board is switched off during execution of an application
  14. Debug System Reset does not work on a 2.0. Zc706 board that has the 2.0 silicon
  15. SDK Hangs After Design Changes in Block Design and Export Hardware (Design with User IP)
  16. While Initializing the bitstream with an ELF file, SDK uses bootloop
