Maybe you can check the debug message when loading display driver. It must be
something wrong with display driver.

Give the error that you are getting when the display driver is up and
running.....

If you are display driver is not showing up any errors, then check out
whether you have include userinterface elements like minimal window
configuration etc...

When you not include these components then also you will have a blank
display...even after you display driver is up...

You can check the s3c2410x_lcd.map file to see in which function the data
abort happened (offset = 0x00001980).

Hi,

Now crashing problem is solved but my LCD shows only upper half portion.
i have faced same problem in boot up,but it got resolved by making buffer
double.
i have done same thing in my display driver but it not working in it.

_U32 (*frameBuffer8Bit)[640*2*480];

frameBuffer8Bit = (_U32 (*)[640*2*480])0x30100000;

s2410LCD->LCDSADDR1 = (((_U32)frameBuffer8Bit >> 22) << 21 ) |
((M5D((_U32)frameBuffer8Bit >> 1)) << 0);

s2410LCD->LCDSADDR2 = M5D((_U32)frameBuffer8Bit + (LCD_XSIZE_TFT * 2 *
LCD_YSIZE_TFT) >> 1);

s2410LCD->LCDSADDR3 = (((LCD_XSIZE_TFT - LCD_XSIZE_TFT) / 1) << 11) |
(LCD_XSIZE_TFT / 1);

plz suggest something to get rid of it.
