Welcome to ARM9 (S3C2440A)

Hi friends ,
                  here i have done it Blinking LED in S3c2440 development board.. also declare serial received character display at 115200 baud rate..

 The source code as:: (any doubt contact me)


#include "def.h"
#include "option.h"
#include "2440addr.h"    
#include "2440lib.h"
#include "2440slib.h"

void dely(U32 tt)
{
   U32 i;
   for(;tt>0;tt--)
   {
     for(i=0;i<10000;i++){}
   }
}
