An issue about compiling the OpenCL to FPGA

Hi,

I met an issue about compiling the OpenCL HelloWorld/Vector_add code to FPGA.

Quartus Prime can offload the VHDL code into the FPGA board but the OpenCL SDK and compiler can not program to the FPGA board instead.

[root@localhost vector_add]# aoc -v device/vector_add.cl -o bin/vector_add.aocx --board de5a_net_i2 --report

aoc: Environment checks are completed successfully.

You are now compiling the full flow!!

aoc: Selected target board de5a_net_i2

aoc: Running OpenCL parser....

Error: Compiler Error, not able to generate hardware

I set up all required driver/BSP (board supported package from Terasic)/env variables/libraries and followed the official manual carefully but still have this issue.

[root@localhost vector_add]# aoc --list-boards

Board list:

de5a_net_i2

But whlie running the aocl diagnose:

[root@localhost vector_add]# aocl diagnose

aocl diagnose: Running diagnose from /root/intelFPGA_pro/17.0/hld/board/de5a_net_i2/linux64/libexec

aocl diagnose: failed 32 times. First error below:

Vendor: Terasic

Found no active device installed on the host machine.

Please make sure to:

1. Set the environment variable AOCL_BOARD_PACKAGE_ROOT to the correct board package.

2. Install the driver from the selected board package.

3. Properly install the device in the host machine.

4. Configure the device with a supported OpenCL design.

5. Reboot the machine if the PCI Express link failed.

Configuration:

FPGA board: Terasic De5a-Net FPGA with Arria 10

Quartus Prime Pro Edition with OpenCL SDK

A similar question in the forum but still didn't have solutions yet:

I am looking for any helps/advise! Thank you so much!

All the best,
