S32DS APEX port configuration of downsample app.

Hi

I am testing image downsampling in S32DS emulation mode, as you known very simple app.

But an error occurred when process controller initializing:

   => input k size(1,1) not divisible with output element k size(2,2):...

   when I trace the error position, following routine cause error at "acf_process_desc_apu.cpp".

       int ACF_Process_Desc_APU::Initialize()

       {

           Create();

           ...

           _graphUsed->ComputeChunkSized();  // error returns 

          ...

      }

I just used downsample graph only (no chunk size setting in the program).

Do you know the reason of error?

I think that in this app., I neet to tranform 2x2 pixels to 1x1 pixel.

So I can design the kernel with input port ek=e0[2,2] and

output port ek=e0[1,1] wher e0=8u1,1 as with  the downsample kernel source.

Or I can design the kernel with input port ek=e0[1,1] where e0=8u2,2 and output port ek=e0[1,1] where e0=8u1,1.

...
