i try to debug the timer program with IAR and olimex LPC2129 but the program don't jump in can you help me please
where is the problem ? this program is the program of www.nxp.com/.../AN10414.pdf
this is the code of my program
#include "LPC21xx.H"
void Initialise(void); __irq void timer_ISR(); __irq __arm void spurious_handler(); //************************ MAIN ******************************* int main (void) { int i,j; // Routine that initialises the LPC2000 device Initialise(); // This for loop helps in identifying the start of the application // Port Indicator: P0.9 for(i=0;i<10;i++) { IOCLR0=0x1000; for(j=0;j<100000;j++); IOSET0=0x1000; for(j=0;j<100000;j++); } // Start Timer1 T1TCR=0x1; // Loop forever while (1) { // Port Indicator: P0.13 //IOCLR0=0x2000; //****************** Step2 ******************** // Uncomment the below block for Step2 VICIntEnClr=0x20; WDFEED=0xAA; WDFEED=0x55; VICIntEnable=0x20; //IOSET0=0x2000; } } //************************ INITIALISE ******************************* void Initialise() { // GPIO IODIR0 = 0xFFFF; IOSET0= 0xFFFF; // Setting pclk same as cclk VPBDIV=0x1; // Timer 1 Configuration T1TCR=0x0; T1TC=0x0; T1PR=0x0; T1PC=0x0; // Setting the Match value T1MR0=0xffff; // Reset and interrupt on match T1MCR=0x3; // VIC Configuration VICIntSelect=0x0; /* Timer 1 selected */ VICIntEnable= 0x20; /* Timer 1 interrupt */ VICVectCntl0= 0x25; /* Address of the ISR */ VICVectAddr0=(unsigned long)timer_ISR; //****************** Step3 ******************** // Uncomment below statement for Step3 VICDefVectAddr=(unsigned long)spurious_handler; //****************** Step2 ******************** // Uncomment the below block for Step2 //Configure the Watchdog WDTC=0xFFFFFFFF; WDMOD=0x1; WDFEED=0xAA; WDFEED=0x55; } //************************ TIMER ISR ******************************* __irq void timer_ISR() { // Port Indicator: P0.13 IOCLR0=0x2000; // Clearing the interrupt and updating the VIC T1IR=0x1; VICVectAddr=0xFF; IOSET0=0x2000; } //******************** SPURIOUS INTERRUPT HANDLER********************* __irq __arm void spurious_handler() { // Port Indicator: P0.15 IOCLR0=0x2000; // Clearing the interrupt and updating the VIC T1IR=0x1; VICVectAddr=0xFF; IOSET0=0x8000; }
