oneAPI FPGA workshop from Wednsday 24 April

Last wednsday I attended Intel OneAPI FPGA Workshop. I was able to complete most of the lab exercises ok. Up to assigning pins, then time ran out and the vm was closed. When I tried this lab on my ...

Hi,

I tried to post a reply yesterday, but today I see it isn't there. Today the link mentioned above https://supporttickets.intel.com does not work.

Thank you,
Peter BUSS

Here is my prepared reply from yesterday.

Should mention, that visual studio 2019 was used. Visual Studio 2022 was after the first attempt installed along with VS 2019, but the nmake failed to work, showing that only vs2019 was there but not vs 2022. So I used vs2019 for the excercises. I ran oneAPI install repare to get vs2022 to work with oneAPI.

Exercise 1 worked fine. That is where the first problem occured.

oneAPI Workshop May 2024 - Exercise 2

All steps were attemped and failed with the same error like the one from step A below. Other steps attempted were B, C, D, E.

Caught a synchronous SYCL exception: Native API failed. Native API returns: -999 (Unknown PI error) -999 (Unknown PI error)

Excercise 3 was not attempted.


Step A: Register-Mapped Invocation Interface and Memory_Mapped Data Interface
____ 1. Go to the sample directory in the command window
a) H:\LID\Features\Interfaces\Ex2
____ 2. Inspect the vector_add.cpp code.
a) Go to Visual Studio Code
b) Navigate to the ..\Ex2\naive and open the file from the src folder
c) This sample demonstrates a kernel that uses a register-mapped invocation interface, and a single shared memory-mapped host data interface.
____ 3. Configure the build directory and make build files for the Naïve sample by running the following commands on the terminal
a) mkdir build
b) cd build
c) cmake -DFPGA_DEVICE=Arria10 .. -G “NMake Makefiles” -DTYPE=NAIVE
____ 4. Perform compilation for emulation and run the kernel on the emulator in the command window
a) nmake fpga_emu
b) vector_add.fpga_emu.exe -> fails - described below
c) The console should display Passed
____ 1. Generate optimization report and inspect report
a) nmake report
b) This compilation command if successful will
