Hi,

Thanks for the information.

Here is a possible solution to root cause the problem.

The idea is you can unintall all the bsps, and only install the a10_ref.

1.Can you confirm which BSP are you using ? Is Arria10 GX BSP that comes with installation package "a10_ref" and is used during aocl install ?

2.Could you share the console output when doing aocl install and aocl uninstall ?

3.To cross check if there is any other BSP installed, make sure there is only one fcd file in the directory specified by the reg key (ie. HKEY_LOCAL_MACHINE\Software\Intel\OpenCL\Boards)

4.How do you compile the host? By using Makefile or using Visual Studio?

Thanks,

Arslan
