Hello everyone!!

 

I have the next problem when i try to use the stratix 10 node 143, with the next line: make fpga.

I can emulated with the next line: make fpga_emu, and the program es correct, but I can´t use "make fpga" because exist error. 

Can you help me please?

 

Thanks a lot.

Step by step:

 

1.-  qsub -I -l walltime=24:00:00 -l nodes=1:fpga_runtime:stratix10:ppn=2 -d .

2.- cd oneAPI-samples/DirectProgramming/C++SYCL_FPGA/Tutorials/Features/loop_coalesce/build/

3.- make fpga_emu

4.- ./loop_coalesce.fpga_emu
Running on device: Intel(R) FPGA Emulation Device
Running on device: Intel(R) FPGA Emulation Device
PASSED: The results are correct

--------------------------------------------------------------------------------------------------------

Then when I try to compile and run in the FPGA stratix 10 with the next steps...

 

1.1.- make fpga

llvm-foreach:
icpx: error: fpga compiler command failed with exit code 1 (use -v to see invocation)
CMakeFiles/fpga.dir/build.make:94: recipe for target 'loop_coalesce.fpga' failed
make[3]: *** [loop_coalesce.fpga] Error 1

make[1]: *** [CMakeFiles/fpga.dir/rule] Error 2
Makefile:144: recipe for target 'fpga' failed
make: *** [fpga] Error 2

 

My problem ocurred when I want to used a node to FPGA, Can you help me please???

 

Thanks...

Hi @ruma,

 

Noted with thanks on the details provided.

As mention you are using the devcloud environment to run the mention design.

Just to check does the simulation compilation completed successfully as well?

 

And we would like to replicate the same to narrow down the issues, could you provided the URL of references design that you are referring to? That would be a great help.

 

Best Wishes

BB

Hello BoonBeng

 

Yes, the simulation compilation was completed successfully.

 

https://github.com/oneapi-src/oneAPI-samples/tree/master/DirectProgramming/C%2B%2BSYCL_FPGA/Tutorials/Features/loop_coalesce

 

This is the URL of referense.

 

Thanks. Regards.-

Hi @ruma,


Noted on the URL of reference and simulation success.

Please do give us some time to try the same and will get back to you once we have any updates.

Thank you for the patients

Hi @ruma,

Thanks for patients, I would suspect that the failure of the full compilation is due to incorrect device set for the compilation.


If you are using the default cmake, it would be setting to Agilex devices instead and that would cause a failure in the quartus compilation.

Hence for that, would suggest to compile with the following cmake to changed the target devices and perform full compilation again:

- cmake .. -DFPGA_DEVICE=intel_s10sx_pac:pac_s10


If it fails again, would suggest to check on the quartus compilation logs in the following locations as below:

- ../loop_coalesce.fpga.prj/quartus_sh_compile.log


Hope that clarify.

Best Wishes

BB
