code of blink led

[xiangfu]

Hi

and how to run it?
another question :
   where is the GTA02's LED? :-)
   what is the best TEXT_BASE value


::::::::::::::
led.c
::::::::::::::
extern void delay(int time);
#define GPBCON        (*(volatile unsigned *)0x56000010)
#define GPBDAT        (*(volatile unsigned *)0x56000014)

#define    LED4_OFF()   (GPBDAT |= (0x2))
void main()
{
   GPBCON = 0x5;
   GPBUP = 0xffff;
   while(1)
   {
   LED3_ON();
   delay(0xfffff);
   LED4_ON();
   delay(0xfffff);
   LED3_OFF() ;
   delay(0xfffff);
   LED4_OFF();

}
::::::::::::::
led.s
::::::::::::::
.text
.global _start
   ldr sp,=1024*4
.extern main
   bl main
.global delay
delay:
   sub   r0,r0,#1
   cmp   r0,#0x0
   bne   delay
   mov   pc,lr
.end

Makefile
::::::::::::::
CROSS_COMPILE=arm-angstrom-linux-gnueabi-
TEXT_BASE=0x0000000
led_on: led.s led.c
   $(CROSS_COMPILE)gcc -g -c -o led.o led.s
   $(CROSS_COMPILE)gcc -g -c -o led_on.o led.c
   $(CROSS_COMPILE)ld -Ttext $(TEXT_BASE) -g led.o led_on.o  -o led_on_c.o
   $(CROSS_COMPILE)objcopy -O binary -S led_on_c.o led_on

clean:
   rm -f *.o
   rm -f led_on

I write some code. but i don't know how to download it to GTA02 #define GPBUP (*(volatile unsigned *)0x56000018) #define LED3_ON() (GPBDAT &= ~(0x1)) #define LED4_ON() (GPBDAT &= ~(0x2)) #define LED3_OFF() (GPBDAT |= (0x1)) delay(0xfffff); } ::::::::::::::
