3. Running Diagnostics

Before running diagnostics, program the board with a pre-compiled OpenCL* bitstream (.aocx file). The following instructions use the hello_world kernel or you may use your own.

  1. Load hello_world OpenCL* kernel:
    aocl program acl0  $OPAE_PLATFORM_ROOT/opencl/hello_world.aocx
    Sample program output:
    aocl program: Running program from $OPAE_PLATFORM_ROOT/opencl/opencl_bsp \
    /linux64/libexec
    Program succeed.
  2. Run the simple diagnostic utility:
    aocl diagnose
    Sample diagnostic output:
