flashing video on Debian Squeeze
« on: April 22, 2012, 04:37:59 pm »

I'm trying to get UQM to run on a computer called the Raspberry Pi.  I have all the required packages installed and have tried installing it from apt-get as well as building it from source.  It works fine from within x-server but the Raspberry Pi is an extremely lightweight computer and doesn't have the oomph to handle running it in X11.  But when I try to run it using just the framebuffer outside X, it will flash the main image then will go black, then it will flash the menu and go black.  Until I load up a new screen or it times out and starts the credits everything will be black.  Does anyone have an idea about what might be causing this issue?

More information, when I start up my screen in 640x480 mode and try to run the program, right after it attempts to initialize the screen it says "segmentation error" I'm using "Pure SDL"

More information, I can't use openGL as the device only support openGL ES.  Is there a port of UQM that uses openGL ES?

The black screen could be in a lot of places: UQM, SDL, SDL_Image, the Linux driver, even the hardware... it will not be easy tracking this down.
The segmentation error gives you a bit more to go on. If you could produce a stack trace, that may give us some indication, but I'm afraid you'll still have to do some serious debugging to get to the bottom of it. How are you with GDB?

You could always try the DirectFB driver (works here on a garden-variety x86 laptop, for what that's worth, don't have ARM hardware to test). Installing libSDL1.2debian-all *should* pull in all needed DirectFB stuff.

I'm using the libsdl1.2debian-alsa drivers, but I'll swap them out and give it a try real quick...  Same issue.  The (somewhat) good news is that this is happening for other sdl programs which makes me think that it's an issue with the way SDL interfaces with the framebuffer, it is a very young device.
