Olimex LPC-E2468 problem on the first step

Started by Bas Prim May 27, 2009
Hello!
I am a novice with this microcontroller and I am trying to start it. I have Olimex LPC-E2468 development board.
I wrote the simplest program in Keil uVision 3 and loaded a hex file by Flash Magic.

#include
int main (void)
{
SCS=0x0001;
FIO1DIR3=0xFF;
FIO1MASK3=0x00;
FIO1PIN3=0x11;

FIO4DIR2=0x03;
FIO4MASK2=0xFC;
FIO4PIN2=0x00;

while (1)
{
}
}

The program should set pins P1[24] and P1[28] to 1 and down P1[25]..P1[27], P1[29]..P[31] to 0 and produce low on P4[16] and P4[17] to light two on-board LEDs.

I shorted jumpers ISP_E and RST_E, programed the lpc2468 but nothing happened. Port pins are floating on 2.3V.

What I am doing wrong?
