[U-Boot-Users] Uboot Splash Screen

Fellow U-booters,
I've run into an issue with my uboot, I want to display a bitmap image when the system boots; however, all the screen does at startup is fade from white to black and back until the OS boots up. I'm currently using an LCD screen with a resolution of 640x480 (landscape) in 8 bit mode, and I have a bitmap with the same dimentions 640*480*8 loaded into the memory at the microcontroller's recommended memory address, and I have the bitmap image converted into a header file and used as the bmp_logo.h file.
Unfortunately, the modifications I've made don't seems to change the fact that the screen just fades from white to black and back, or really how fast the screen does so--the image I'm using is mostly white with some red text.
Thank you, Roger Williamson Orbital TMS -- Colombia CE Software Engineer (443) 259-7320

So you probably did not configure your display controller correctly.
