Hi @HKim27​

Sorry i missed your reply. Thank you for following up.

Could you run the below steps:

Could you reboot your system?

Source init_env.sh

aocl install

program a hello_world.aocx to initialize the board

aocl diagnose (it should show the status as "Passed")

Then go back to performing: https://www.intel.com/content/altera-www/global/en_us/index/documentation/fvf1521490619217.html#nms1523294913946

make sure you have copied the vector_add.aocx into the "bin" folder

cp $OPAE_PLATFORM_ROOT/opencl/vector_add.aocx ./bin

Also, check if you have set your hugepages.

If this still fails, please confirm you meet the system requirement: https://www.intel.com/content/www/us/en/programmable/documentation/iyu1522005567196.html#oeh1528996494398

    @JwChin​

    I finally found the solution. (after 8 month!!!)

    Initialization script inside Intel Acceleration Stack Version 1.2 (inteldevstack/init_env.sh) has this line:

    export CL_CONTEXT_COMPILER_MODE_INTELFPGA=3

    According to the documentation, this environment variable prevent reconfiguration during OpenCL host execution.

    By unsetting this, reconfiguration works well.
