hello

i made a wince6 for mini2440, all is ok it runs well on my mini2440 with
L80 screen.
The problem is that my screen switch on and off wery quickly each time i
make something in wince , for example is i make a simple clicj on an icon,
it switch off and on a few times but very quickly.

I tried with arm9.net  winc6 image, the problem is the same.

We had the same problem at the samples of mini2440 + L80 kits from
friendlyARM at Guangzhou. 

When we turned back to Turkey, we tried to compile different versions of
WinCE images to solve the problem. Nevertheless, problem continued. 

After days of seaching and checking the mini2440 drivers, we encountered a
Pixel Clock definition at s3c2440a_lcd.h file.

After testing we had found PixClock value must be set to "4" in order to
get stable display.

Hi MertALTA,

Thank you soo much for this information, with the parameter 'LCD_PIXCLOCK'
set to '4', the L80 kit works perfectly with Windows CE 6.0 !

Congratulations to have solve this problem ;)
