Question

Hello all,

I am new to both this forum and FPGA with OpenCL - I have some questions I hope someone can help me with.

I have intelFPGA_pro v 16.1 installed in Ubuntu Linux OS and am just trying to test out the system by running the 'aocl diagnose' operation. However, when I run it I get the following output:

"cannot find board_env.xml in /board/nalla_pcie"

I checked in /hdl/board/nalla_pcie and 'board_env.xml' is located in this directory. Can anyone tell me what is wrong? I am looking forward to getting some interesting work done :)

Thank you in advance for any help/hints.

Your environmental variables should look like this:  export ALTERAOCLSDKROOT="*quartus_install_folder*/hld"
export AOCL_BOARD_PACKAGE_ROOT="$ALTERAOCLSDKROOT/board/nalla_pcie"  Since aoc is looking for the BSP in "/board/nalla_pcie", it means "ALTERAOCLSDKROOT" is not pointing to anything and hence, AOCL_BOARD_PACKAGE_ROOT is pointing to "/board/nalla_pcie".

I made the changes you suggested and 'aocl diagnose' executes further however it now has another issue :cry: - probably related to the same issue as the original issue.  When I execute 'aocl diagnose' now I get the following output:  "aocl diagnose: Error while loading shared libraries: libnalla_pcie_mmd.so: cannot open shared object file: no such file or directory"  I checked and the libnalla_pcie_mmd.so library exists in /board/nalla_pcie/linux64/lib. Is there another environment variable that I need to set such that 'aocl' will be able to properly locate this library?  Thank you again for your response and help.:)

You should add the path to that library to LD_LIBRARY_PATH. Check section 3.3 of this document (https://www.altera.com/en_us/pdfs/literature/hb/opencl-sdk/aocl_getting_started.pdf). That document is very important. I suggest reading and following it step by step.

Hi HRZ,

Thank you everything works with regards to all my paths :)

However now when I run diagnose I get a completely different error - it fails. Do you have any suggestions? I copy and paste the output from running diagnose below.

aocl diagnose aclnalla_pcie0

aocl diagnose: Running diagnose from /usr2/intelFPGA_pro/16.1/hld/board/nalla_pcie/linux64/libexec

Board package name :nalla_pcie

Using dev_num = 0

Using platform: Intel(R) FPGA SDK for OpenCL(TM)

Failed clGetDeviceIDs.

Error code: -1

aocl diagnose: failed.

Thank you again for all your help.
