hello all,

&nbsp;
  

I used&nbsp;"CreateDevice" API to&nbsp;connect D3DM device.&nbsp;and returned&nbsp;an error value --&nbsp;D3DMERR\_INVALIDDEVICE, &nbsp;it seems platform doesn't support D3DM.&nbsp; 
  

Hardware is Sirf prima TT442, accroding white paper, it integrated MBX-lite core, so D3DM should be supported, and I built OS softaware by myself, certainly I checked all D3DM items in catalog items view. 
  

&nbsp;
  

maybe you know why?
  

&nbsp;
  

please refer to following source code.
  

&nbsp;
  

if( NULL == ( g\_pD3DM = Direct3DMobileCreate( D3DM\_SDK\_VERSION ) ) )  
&nbsp;&nbsp;return E\_FAIL;
  

&nbsp;D3DMPRESENT\_PARAMETERS d3dmpp;   
&nbsp;memset( &d3dmpp, 0, sizeof(d3dmpp) );  
&nbsp;d3dmpp.Windowed = TRUE;  
&nbsp;d3dmpp.SwapEffect = D3DMSWAPEFFECT\_DISCARD;  
&nbsp;d3dmpp.BackBufferFormat = D3DMFMT\_UNKNOWN;  
&nbsp;d3dmpp.EnableAutoDepthStencil = TRUE;  
&nbsp;d3dmpp.AutoDepthStencilFormat = D3DMFMT\_D16;
  

  
&nbsp;UINT uAdapter D3DMADAPTER\_DEFAULT;  
&nbsp;  
&nbsp;HRESULT hRes = g\_pD3DM-\>CreateDevice( uAdapter,   
&nbsp;&nbsp;D3DMDEVTYPE\_DEFAULT,  
&nbsp;&nbsp;hWnd, 0,  
&nbsp;&nbsp;&d3dmpp, &g\_pd3dmDevice );  
&nbsp;if( FAILED( hRes ) )  
&nbsp;{  
&nbsp;&nbsp;ErrorOutput(hRes);  
&nbsp;&nbsp;OutputDebugString(TEXT("Unable to create a D3DM device.n"));  
&nbsp;&nbsp;return E\_FAIL;  
&nbsp;}
  

&nbsp;
  

Best regards
  

Gavin

If you have access to our drivers to build them for this platform then your enquiries should be directed through IPGear. Otherwise, you may have a software implementation of D3DM, in which case we can't really help you, I'm afraid.
