[SOLVED] Flash programming using JTAG

[bikashh]

Hello all,
I am a newbie in embedded field and trying to download my program into Flash using JTAG but couldn't.
I've loaded the source file and wrote just a simple program to flash LED ON and OFF. code is written below

#include<LPC23xx.H>

int main(void)
{
int i;
PINSEL4=0xFFFFFFFC;
FIO2CLR=0x00000001;
while(1)
{
FIO2SET=0x00000001;
for(i=0;i<40000;i++)
{;}
FIO2CLR=0x00000001;
}
}


Any help would be appreciable. Thanks in advance

why no delay after you turn off led i.e. clear port. if you dont give dely then it will appear that led is always ON,
give same delay for clear within while loop

why are you not setting the direction of the port pin , as output port?

check in the simulator if it is working before testing on hardware
