    System Lockup With Render-To-Texture

    Hi, I've been continuing to look at this problem on and off (mostly off :-)) over the last months, and I think I've finally got a solution. A combination of the following ingredients seems to allow render-to-texture to work without locking up the system: Running a 2.6.37 kernel. Mine...

    System Lockup With Render-To-Texture

    Maybe interesting extra information, maybe not: the older "OMAP35x_Graphics_SDK_setuplinux_3_01_00_02.bin" release doesn't work any better with my Debian setup, though the crashing behaviour is slightly different (happening sooner or later). This is also using a pandora-37 kernel, and applying a...

    System Lockup With Render-To-Texture

    Thanks for the reply! I've reduced the test case it a little, to a single source file at least. It could probably go a little smaller by hardwiring matrices etc., but I think that'll just obscure things unnecessarily. New download in the same location as before, i.e...

    System Lockup With Render-To-Texture

    After rather a lot of time, I've managed to get a 2.6.37 kernel (from the pandora-37 git branch) running on my Pandora. Interestingly, and frustratingly, this doesn't seem to have fixed my original issue though: my code still manages to lock up the SGX. With the following recipe, approximately...

    System Lockup With Render-To-Texture

    I've now managed to get my original project, and the cut-down testcase, both working flawlessly (err, or at least not crashing) on an IGEPv2 board, using (I think) the same version of the SGX drivers, but with a later kernel (*). This to me points very strongly towards a kernel issue. I guess...

    System Lockup With Render-To-Texture

    Thanks for the reply (wow that was quick!). The -mfloat-abi=softfp option unfortunately doesn't fix anything in the main project, but gives a really interesting data point. I have about half a theory about what might be happening now I think: the binary SGX driver probably contains VFP/NEON...

    System Lockup With Render-To-Texture

    Hi, I'm working on porting an old, half-finished project of mine over to GLES2 on the Pandora, but I've hit what appears to be a driver or kernel bug which results in a full-system lockup when rendering to a texture (using a framebuffer object). I'm running Hotfix 5 & using a cross-compiler...
