OpenCL memory banks

Hello,

From the hello world example, I got:

CL_DEVICE_GLOBAL_MEM_SIZE = 4294967296,

which means 4GB global memory.

I am using a nallatech 385a7 board, so why the global memory size I got from the example is not 8GB instead? (2banks of 4GB). Is it possible to use all the 8GB memory on board?

Thanks.

    Hi,

    I would recommend upgrading the BSP to the latest available version which supports 8GB of global memory on the 385 A7. The current version is R001.003.0001 and was tested in Quartus-II 15.0.0.145.

    You should contact Nallatech directly with this form to obtain access to the latest BSP:

    Thanks
