Switching to new display resolution, suddenly Graphics SDK demos stop working

Glenn Wainwright
Expert 1605 points
Other Parts Discussed in Thread: DM3730, OMAP3530

I've been working for a while now on a 640x480 display with OpenGLES and Qt on a DM3730.

Now, I've got a new Sharp display that I'm integrating, with a 1280x800 resolution (rotated 90 degrees).  With those changes, none of the OpenGL SDK demos work anymore - errors below.  Switch back to the 640x480 display (with no rotation) and everything works fine again.  Any idea what I could be missing?

Thanks,
Glenn Wainwright

    Forgot to mention, all of the modules in rc.pvr load without any errors in both cases.

    Glenn,

    Can you increase the vram parameters in bootargs? 

  • 0 in reply to Renjith Thomas
    Expert 1605 points

    Thank you for your response.  That was actually one of the first tests that I did - doubling the vram settings in the bootargs to "vram=20M omapfb.vram=1:20M" has no effect on the issue.

    Glenn,

    Can you try with even more memory as 1280x800 is 3.3 times of 640x480. So can you try with 40MB?

    Not a problem - that seems to give the same result.

    Have you re-built the GFX SDK after the modification? Also does your device bootup properly without SGX enabled with the new resolution? 

    I have seen similar errors in WINCE before. There the issue was with the display driver not getting link to the SGX library properly. 

  • 0 in reply to Renjith Thomas
    Expert 1605 points

    So the display itself is not actually operational yet - the electrical guys are working on a couple hardware fixes to get it working.  So while they're doing that, I'm trying to work through these issues that came up in software.  So, unfortunately, I cannot confirm that the standard fbdev display stuff is working yet - I can just confirm that it doesn't throw any crazy errors. 

    The GFX SDK has definitely been rebuilt and re-installed after the kernel was changed for the new display - I specifically rebuilt it to get this debug output.

    Looking through the SDK code, it looks like there might be more debug information coming from PDUMP - do you know how I can get access to it - that might tell me more.

    Am I reading this correctly?  I'm trying to figure out what exactly "Error -18" is.  Is it PVRSRV_ERROR_TOOMANYBUFFERS, or something else?

  • 0 in reply to Glenn Wainwright
    Expert 1605 points

    Looks like that is the case.  In omaplfb::CreateDCSwapChain, the input buffer count is 2, but the max number of buffers in psDevInfo->sDisplayInfo.ui32MaxSwapChainBuffers is 1.  If you have any idea what those buffers are referring to, that might help me clear this.

    Glenn,

    I think issue is because of the number of buffers supported by the framebuffer driver is less. You can alter this in the framebuffer driver and try to double the number of buffers and see whether the failure goes away.

    Please take a look at this post, it should be relevant here as well.
