    I finally found the solution. The answer is : compiling c++ code in fpga mode with i++ compiler needs a huge amount of Ram and hdd resource for page filing. For example a cycloneV design needs about 64gb ram and resource. it depends on your design. That is it.

Hi @Engineer87,

Thanks for the information, good to know that some example design are programmed successfully for CycloneV devices.

Follow up question, are you having issues on the Arria10 or CycloneV devices? Is it correct to say example design both successfully compiled and program on Arria10 and CycloneV and just this design are failing in both devices for hardware compilation?


The success programmed previously rules out the environment setting issues, hence we might be seeing some code or hardware issues.

Hope to hear from you soon.


Regards

BB

    Hey. Thanks for your attention. Yes examples of the intel is correctly program in cyclonev or arria10. It seems the example designs are very simple and small. For example counter and ... . I think the error command is too long reffer to a buffer or for example option jn program that should be extended or some thing. What does it mean too long? Too long for what?
    Thank you.
