There is no need to embed the image data in the U-Boot binary. You can also use the "bmp" command or "splashimage" environment variable. > Now I have to display text(character) on the display.

First, when defining CONFIG_CFB_CONSOLE in the config file you additionally have to provide video_hw_init() function which returns an initialised GraphicDevice structure for your device. Also set "stdout" and "stderr" environment variables to "vga" and use printf() to display characters. You can use available drivers, i.e. drivers/video/omap3_dss.c, as reference. > SASKEN BUSINESS DISCLAIMER: This message may contain... ... please avoid such disclaimers when posting to a public mainling list.
