Honored Contributorhelloworld issue on arria10Gx development kit
Hi,
I am trying to compile and run hello_world example of OpenCL SDK on Arria10Gx development board. Example fails to run with below error code. kindly check below steps and comment on any wrong doing. user@user:~/opencl_examples/hello_world$ bin/host Querying platform for info: ========================== CL_PLATFORM_NAME = Intel(R) OpenCL CL_PLATFORM_VENDOR = Intel(R) Corporation CL_PLATFORM_VERSION = OpenCL 2.0 Querying device for info: ======================== CL_DEVICE_NAME = Intel(R) Core(TM) i7-6800K CPU @ 3.40GHz CL_DEVICE_VENDOR = Intel(R) Corporation CL_DEVICE_VENDOR_ID = 32902 CL_DEVICE_VERSION = OpenCL 2.0 (Build 475) CL_DRIVER_VERSION = 1.2.0.475 CL_DEVICE_ADDRESS_BITS = 64 CL_DEVICE_AVAILABLE = true CL_DEVICE_ENDIAN_LITTLE = true CL_DEVICE_GLOBAL_MEM_CACHE_SIZE = 262144 CL_DEVICE_GLOBAL_MEM_CACHELINE_SIZE = 64 CL_DEVICE_GLOBAL_MEM_SIZE = 16734322688 CL_DEVICE_IMAGE_SUPPORT = true CL_DEVICE_LOCAL_MEM_SIZE = 32768 CL_DEVICE_MAX_CLOCK_FREQUENCY = 3400 CL_DEVICE_MAX_COMPUTE_UNITS = 12 CL_DEVICE_MAX_CONSTANT_ARGS = 480 CL_DEVICE_MAX_CONSTANT_BUFFER_SIZE = 131072 CL_DEVICE_MAX_WORK_ITEM_DIMENSIONS = 3 CL_DEVICE_MEM_BASE_ADDR_ALIGN = 1024 CL_DEVICE_MIN_DATA_TYPE_ALIGN_SIZE = 128 CL_DEVICE_PREFERRED_VECTOR_WIDTH_CHAR = 1 CL_DEVICE_PREFERRED_VECTOR_WIDTH_SHORT = 1 CL_DEVICE_PREFERRED_VECTOR_WIDTH_INT = 1 CL_DEVICE_PREFERRED_VECTOR_WIDTH_LONG = 1 CL_DEVICE_PREFERRED_VECTOR_WIDTH_FLOAT = 1 CL_DEVICE_PREFERRED_VECTOR_WIDTH_DOUBLE = 1 Command queue out of order? = true Command queue profiling enabled? = true Using AOCX: hello_world.aocx Context callback: clCreateProgramWithBinary failed ERROR: CL_INVALID_BINARY Location: ../common/src/AOCLUtils/opencl.cpp:392 Failed to create program with binary ============================================================== Steps I followed are : ------------------------ 1. Installed and setup Intel OpenCL SDK for FPGA. 2. Configured Arria10Gx development kit as per instructions specified in document https://www.altera.com/en_us/pdfs/literature/an/an807.pdf 3. compiled OpenCL kernel with below command and generated hello_world.aocx file. aoc device/hello_world.cl -o bin/hello_world.aocx -board a10gx 4. compiled host program with make command 5. used "bin/host" command to run host program. Also here is the info about detected devices user@user:~/opencl_examples/hello_world$ aoc -list-boards Board list: a10gx Board Package: /home/mobiliya/intelFPGA_pro/17.1/hld/board/a10_ref a10gx_hostch Board Package: /home/mobiliya/intelFPGA_pro/17.1/hld/board/a10_ref Channels: host_to_dev, dev_to_host Thanks. regards Vinod26 Replies
Altera_ForumSee to opencl.cpp, line 392. In my version is code:
checkError(status, "Failed to create program with binary"); for a previous function call of clCreateProgramWithBinary(). May be, in FPGA on Power On is downloaded not OpenCL image with BSP, search appropriate .sof or .rbf. In kit by default lie non-OpenCL image.- Altera_Forum
You are compiling your host code against the wrong OpenCL SDK; the host code is trying to run the OpenCL kernel on your CPU (CL_DEVICE_NAME = Intel(R) Core(TM) i7-6800K CPU @ 3.40), rather than your FPGA.

I compiled helloworld example as per readme file. aoc -march=emulator device/hello_world.cl -o bin/hello_world.aocx -board=a10gx and ran host code by using "bin/host". Did I missed any device/target setting??

Try to uninstall your SDK an install again, listen to HRZ, he say that your HelloWorld is runned on Intel processor.
May be another OpenCL SDK (not for FPGA) be installed on your PC ? In debugger DS-5 step by step you may see executing of your HW ? On init may be returned not 1 OpenCL realization, and on default index [0] is used non-FPGA. I see this on PC with installed NVidia GPU card and SDK for GPU. My Altera kit on Cyclone V say from embedded Linux:
Your must see similar line with "a10_ref", no "CL_DEVICE_NAME = Intel(R) Core(TM) i7-6800K CPU @ 3.40GHz".CL_DEVICE_NAME = c5soc : Cyclone V SoC Development kit - Altera_Forum--- Quote Start --- Thanks for the response. I compiled helloworld example as per readme file. aoc -march=emulator device/hello_world.cl -o bin/hello_world.aocx -board=a10gx and ran host code by using "bin/host". Did I missed any device/target setting?? --- Quote End --- "-march=emulator" compiles for emulation. Are you trying to run the code on an actual board, or are you trying to emulate it? If you are trying to run on a board, you should remove "-march=emulator" from your command line.

Actually I compiled for actual board without "-march=emulator". i.e aoc device/hello_world.cl -o bin/hello_world.aocx -board=a10gx

Then there must be something wrong with your environmental variables somewhere. If the compiled host code is detecting your CPU, but not your FPGA, it means it is being compiled against some SDK other than Altera's, or that your FPGA is not being detected and hence, the host code is using the CPU. Have you made sure your board is detected correctly? e.g. does your board pass "aocl diagnose"?

But now seeing below issue for both "helloworld" and "vect_add" sample application. mobiliya@mobiliya:~/opencl_examples/vectoradd/vector_add$ bin/host Initializing OpenCL ERROR: UNRECOGNIZED ERROR CODE (-1001) Location: ../common/src/AOCLUtils/opencl.cpp:297 Query for number of platforms failed Kindly note that all environment variables and Aletra Arria10Gx board settings are fine as described in earlier mails. Also both "aocl diagnose" and "lspci" commands work as expected.
