ModeratorHi @StefanoC,
Good to know that the emulation are successful, hence that should tell us that the required component/libraries might be correctly available.
As for the hardware compilation suspecting there might be some lower caps on the 'gx' which is causing some problem.
Would suggest to try with 'Cyclone10GX'.
If that does not work, maybe you can try with the full compilation command instead as below:
- icpx -fsycl -fintelfpga -DFPGA_HARDWARE -I../../../../include vector_add.cpp -Xshardware -Xstarget=Cyclone10GX -o vector_add.fpga
And for the hardware compilation from your end, is the build completed successfully with the bitsteam file generated? Is there a .prj folder generated?
Regards
BB
Occasional ContributorWhile the part1 works, I could compile and run it (although not without the make command but with the full command you shared), part2 does NOT work. Part1 is not interesting after all as it's the CPU that is doing the calculation, part2 is where I am mostly interested because the fpga does something. And interestingly enough the error I get is probably the very same I always had in the first place when I started this thread (PI_ERROR something..).
See below the issue with part2 (also the other abnormal thing is the cout that prints: "Running on device: SimulatorDevice" since given the compiler flag FPGA_HARDWARE it shouldn't say SimulatorDevice (unless something is wrong with the Cyclone10GX driver/oneAPI hardware support?

This process may take several hours to complete. Prior to performing this compile, be sure to check the reports to ensure the design will meet your performance targets.
