my question is: 1、the OpenGL ES program will stop when run long time? 2、can't debug OpenGL ES program many times?

platform : Omap3530、wince6.0、DVSDK_6.10.0 、PowerVR_6.10 BSP package.

In my board, I can run OpenGLES program, eg: F:\WINCE600\PUBLIC\PowerVR-SDK\OGLES2\TrainingCourse\RenderToTexture. but, the OGLES2RenderToTexture.exe have two strange scene.

the one strange scene: when the OGLES2RenderToTexture.exe run long time, the program's window will stop, the program is silence, and the program is not terminate, the wince operate system is run normally.

the second strange scene: the wince's OGLES2RenderToTexture.exe and the windowsXP's OGLES2RenderToTexture.exe, they effect seeing is very different, the effect of wince's OGLES2RenderToTexture.exe is too badly.

because of these strange scene, so, I doing some test.

test 1: when I test 01_Initialization, the path is F:\WINCE600\PUBLIC\PowerVR-SDK\OGLES2\TrainingCourse\01_Initialization. the program 's Description is : Basic Tutorial that shows step-by-step how to initialize OpenGL ES2.0, use it for clearing the screen with different colours and terminate it. I found : if increase the program's terminate time, the program will stop, and will not terminate at all. this means the program is stoped to wait some OpenGLES function's return. so, I think OpenGLES have some program.

test 2: when I test 02_HelloTriangle，the path is F:\WINCE600\PUBLIC\PowerVR-SDK\OGLES2\TrainingCourse\02_HelloTriangle. the program is description is :Basic Tutorial that shows step-by-step how to initialize OpenGL ES 2.0, use it for drawing a triangle and terminate it. I found : I can debug the program ,but can't many times to debug the program. when I modify the source code, I will can't to debug, the OpenGLES will have question，the program's window will gray. so I need to reset board. question is: 1、why the opengles program will stop when run long time? 2、why can't debug program many times?

Yfm1202, You need to get the latest version of the Graphics SDK (6.12) from bsquare and it will resolve these problems. Also, see my new article on this wiki "Render to Texture with OpenGL ES".
