openCL memory error

Hello, This is my first thread, I´m new at openCL and I´m doing some work to integrate this technology with some other software. So I´m trying to execute an aocx inside another program written...

Hello Again,

Maybe I can give more info about the problem. I have generated a library in my host for the ARM device. I have got the pointer for every element which is called in clCreateProgramWithBinary:

context: 0x18dc0c

size: 0x18dc34

buffer: 0x18dc2c

binary status: 0x18dc28

status: 0x18dc20

device: 0x18dc08

program: 0x18dc18

*** Error in `../../bin/linux-arm/hpsfpga1dtest': munmap_chunk(): invalid pointer: 0x00248eb8 ***

Maybe the issue is related to Host Compilation? Do you know a way to discover it?

I have tried another way to load the binary with AOCL_utils from Altera:

scoped_array<cl_device_id> devices;

cl_uint num_devices;

devices.reset(getDevices(platform, CL_DEVICE_TYPE_ALL, &num_devices));

// We'll just use the first device.

device = devices[0];

std::string binary_file = getBoardBinaryFile("./hello_world", device);

printf("Using AOCX: %s\n", binary_file.c_str());

program = createProgramFromBinary(context, binary_file.c_str(), devices, num_devices);

However I get the same result. I would be glad to receive any feedback, thanks!
