Displaying during bootup, ie. a Splash Screen

SteveG10854

I’d like to display a ‘splash screen’ while the system is booting rather than the blank screen that’s on the DM355 DVEVM now. I guess when the display OSD driver has been configured I can write a bitmap or suchlike out to it, and I’d like to get the splash screen on as soon as possible during the bootup. Could you tell me please what I need to do to get a splash screen shown? Many thanks.

    To get a splash screen up as soon as possible you would need to modify U-Boot to configure and activate the VPBE and than to draw your image of choice in the frame buffer, I have seen this done before however I do not have a good reference or example of it. This would get your splash screen up almost immediately after power on.

    From a Linux perspective you can change the logo that shows up when the display driver is loaded from within 'make menuconfig' when you rebuild your kernel, I don't have my DM355 kernel source in front of me to take a look for it, but there is a logo option in there that is likely currently loading a tiny MontaVista logo, you would have to import your particular logo.
