my board type "at91sam9261ek".
now, I want to use the Splash Screen function in u-boot software.
I define "CONFIG_SPLASH_SCREEN" in the ../include/configs/at91sam9261ek.h file.
and I changes the ../common/lcd.c file as :
static void *lcd_logo (void)
{
#ifdef CONFIG_LCD_INFO
char info[80];
char temp[32];
#ifdef CONFIG_ATMEL_LCD
int i;
ulong dest;
ulong dram_size, nand_size;
#endif
#endif /* CONFIG_LCD_INFO */

#ifdef CONFIG_SPLASH_SCREEN
char *s;
int rc;
ulong bmp_addr;
char *bmp_s;
char *bmp_dest;
ulong addr;
static int do_splash = 1;

if (do_splash && (s = getenv("splashimage")) != NULL) {

addr = simple_strtoul(s, NULL, 16);

do_splash = 0;

#ifdef CONFIG_VIDEO_BMP_GZIP
bmp_image_t *bmp = (bmp_image_t *)addr;
unsigned long len;

if (!((bmp->header.signature[0]=='B') &&
(bmp->header.signature[1]=='M'))) {
addr = (ulong)gunzip_bmp(addr, &len);
}
#endif

if((bmp_dest = getenv("bmp_dest")) != NULL)
{
dest = simple_strtoul(bmp_dest, NULL, 16);
if((bmp_s = getenv("bmp_size")) != NULL)
{
bmp_addr = simple_strtoul(bmp_s, NULL, 16);
rc = read_dataflash(addr, bmp_addr, (char *) dest);

if (lcd_display_bitmap (dest, 0, 0) == 0) {
return ((void *)lcd_base);
}
}
}
}
#endif /* CONFIG_SPLASH_SCREEN */
...
...
}
and, I set the env in u-boot cmd line.
setenv splashimage 0xC0040000
setenv bmp_size size //(size = bmp picture size)
setenv bmp_dest addr //(addr = SDRAM addr)
saveenv

reset the cpu.
the bmp picture is screen on the lcd.
but the bmp is in incline.
I do not know how to do with followed.

please help me for this problem, thanks!
