PipeCNN: ERROR: CL_INVALID_BINARY

Dear Prof. @doonny , I use De1-SoC and Angstrom v2014.12 - Kernel , I changed, const char *vendor_name = "altera"; in derictory …/project/host/main.cpp because of when *vendor_name = “Intel” there was Error “Unable to find the desired OpenCL platform.”

now there is new error;

./run.exe conv.aocx

Loading kernel/binary from file conv.aocx 
ERROR: CL_INVALID_BINARY

Failed to create program with binary

So i want to know, There are another things do i want to change ? (because of changing const char *vendor_name = "altera";)?

Thank You

@Fnajjar if you able to complete the HW emulation also you can help to @DasunBhanuka to get it work. cause you both have same problem right. Thank You.

Dear @doonny , @thinkoco , @Fnajjar When i compile the ./run.exe conv.aocx (two generate file from the host computer) in my arm based de1-soc FPGA, the error occurs,

Loading kernel/binary from file conv.aocx
ERROR: CL_INVALID_BINARY
Location: ../common/ocl_util.cpp:415
Failed to create program with binary

and in location : …/common/ocl_util.cpp:415 there is;

#ifdef FPGA_DEVICE
  cl_program program = clCreateProgramWithBinary(context, num_devices,devices,         binary_lengths,
    (const unsigned char **) binaries.get(), binary_status, &status);
  checkError(status, "Failed to create program with binary");

So i think the problem is in const unsigned char **. Because I found some differences in x86 and arm32. Can you please help me to slove this problem?
