Dear Simon,

I don't think this is as it should be. Any frame buffer that actually gets used as such should be located in the memory area specifically allocated for this purpose using lcd_setmem(). This is especially important when you load a splash screen image and intend to display it flicker-free when booting an OS. If you use malloc() or memalign(), it will be memory in the malloc arena, which gets overwritten when an OS boots, resulting in a corrupted display.
Note: I added Anatolij, our video custodian to the Cc: list.
OK, well in that case we should deprecate this business of using a separate memory buffer as a frame buffer, and make people uncompress the BMP to the normal frame buffer. It would simplify a few things and I doubt there would be a speed penalty (or at least it could be corrected by decompressing directly to the frame buffer).
Agreed - thanks!
Best regards,
Wolfgang Denk
