Thanks Miroslav, I did add "-mno-unaligned-access" to those modules related to splash display, and splash display is going fine. But another issue comes out: the speed of drawing splash bmp is obviously slower than that in my another arm9(imx28) based board. This board is setup on 1GHz with am3354. I wonder if some cache options should be included in config file, Is that possible?
