It depends on images tested. Most of them are: "PC bitmap, Windows 3.x format, XXX x YY x 8". Just see tools/logos/*.bmp in U-Boot sources. I also created my own BMP image using convert tool with the following option : "-depth 8 -colors 256 -compress none -alpha off". > which u-boot framebuffer driver is used ? On snow config, this should be the exynos framebuffer driver.
