PowerVR SDK and DDK on OMAP35x and VBO using

Other Parts Discussed in Thread: OMAP3530

Hello,

 We are currently working on the OMAP3530 processor on EVM Board with WinCE 6.0 R2 and we are using BSP 6.10 from Bsquare.

 

1.We would like to use PvrTune to check some performance issues with OGLES but according to Imagination Technologies OGLES driver version included in your last BSP are to old to work with the PVRTune that they provided to us. Moreover Imagination Technologies told us that PVRScopeServices.dll must be included as a driver in your BSP to make work PVRTune.

 Have you got any idea about this problem ? Did you plan to release a BSP including SDK v2.4 and a DDK v1.4 ? On your latest BSP 6.13, OGLES driver are not the latest (SDK v2.3 and DDK 1.3).

 

2. We want to use VertexBufferObject but we noticed a big decrease of FPS using VBO (on BSP 6.10 and 6.12.04) whereas Imgagination told us that it should be quicker after the VBO has been allaocated and used on several frames. Can you confirm that it is a problem on this platform with this BSP version (6.12.04) ? In this case have you planned to optimize it ?

 

Thanks for your answers.

 Best Regards.

    As you correctly pointed out BSP 6.13 is using older version of graphics SDK and DDK. We are aware of this and are planning to migrate to latest DDK version 1.5 - this porting effort will start soon but we don't have target release defined yet. We will also verify VBO performance in the new port.

    thanks
