Posted by Yash I think P6 Data register and control register addresses are swapped.

Hi,
Can you try following LED Blinking program ? It works on EVB3644F.
#define P6DR (*(volatile char *)(0xffd9))
int count = 0;
{
}
{
count += x;
}
{
int i,j;
for (j = 0; j < 1000; j++)
for (i=0; i<delay; i++)
dummy();
}
void main (void)
{
int i, j =0;
P6CR |= 0x01; /* Set bit 0 for output */
{
somewhere (j++);
for (i = 0; i < 10; i++)
{
/* Toggle the light */
P6DR ^= 0x01;
sleep (userdelay);
}
}
}
