How to create a customize slash screen in eboot stage on WinCE 6 R3? RRS feed

  • Question

  • Hi All,

      My development EVM is TI AM35X series that it had support the show logo feature in the BSP but it just only displays the static logo on OSD.

      I would like to do some fancy changes while CE boot-up that something like the dynamic process bar or debug message on my OSD.

      I just learn to develop WinCE in recent weeks hope someone can give me  hints to make it happen.

      Thanks a lot!

  • if you want to show a logo, Normally A single frame buffer is given to Display controller DMA. if you want to do some kind of animation in bootloader, you can create multiple frames(each frame has different action) and reserve memory for each frames which shouldn't get disturbed by OS during booting until the display driver is loaded. Create a chain descriptor for multiple frame buffer and load the display DMA in bootloader.

  • Great! Vinoth.R

    Thanks for your reply and I got this design concept.

    There is another question about output debug message on OSD.

    If I want to show debug message on OSD it seems that I need to build the font bitmap first.

    Is my understand correctly? or I miss some key point?

    Thanks again
