Hello,

I'm trying register base interrupt control. But not working.(problem *.s files)

I do not

want to use to OSAL library.

Not starting interrupt. Example Code: 

//Orhan YILMAZ
//Timer Example
typedef
enum
{
FALSE,
TRUE
}
BOOL
;
void
StartupInit(
void
);
void
Port_conig(
void
);
void
WDT_disable(
void
);
void
PIT0_Init(unsigned 
int
TimeOut);
void
PIT0_Start(
void
);
//void PIT_0_Handler(void);
void
Interrup_Enable(
void
);
#include ''components.h''
#include ''xpc560b.h''
/*
* Application entry point.
*/
unsigned 
long
i = 0;
int
main(
void
) {
componentsInit();
//CLK Init.
StartupInit();
//WDT Disable
WDT_disable();
//Port
Port_conig();
//Timer
PIT0_Init(0xFFFFF);
//IRQ Config
Interrup_Enable();
PIT0_Start();
while
(TRUE) {
if
(i == 0xFFFFFF)
{
//SIU.GPDO[90].B.PDO ^= 1;
i = 0;
}
i++;
}
}
//PORT CONFIGURATION
void
Port_conig(
void
)
{
//Working Led
SIU.PCR[90].B.OBE = 1;
SIU.GPDO[90].B.PDO = 0;
//Output Low
}
//PIT0 Initial Function
void
PIT0_Init(unsigned 
int
TimeOut)
{

PIT.PITMCR.R = 0x000000001;
//Enable PIT and Configure to stop in debug mode
PIT.CH[0].LDVAL.R = TimeOut;
//Timeout enter
//Tclk = SystemCLK
INTC_PSR(PIT0_VECTOR)=5;
//PIT_0_Handler, 59, 5;
IRQ_HANDLER(PIT_0_Handler);
}
//PIT0 Start Function
void
PIT0_Start(
void
)
{
//TIE = 1 Timer Interrup Enable
//TEN = 1 Timer Enable
PIT.CH[0].TCTRL.R = 3;
}
void
WDT_disable(
void
)
{
//Watchdog Timer Disable
SWT.SR.R = 0x0000c520; 
/* Write keys to clear soft lock bit */
SWT.SR.R = 0x0000d928;
SWT.CR.R = 0x8000010A; 
/* Clear watchdog enable (WEN) */
}
/*************************
*CLK CONFIGURATION

void
StartupInit(
void
)
{

//Check Configurations
while
(ME.GS.B.MTRANS);
//Global Status Register wait for mode transition to complete
while
(ME.GS.B.CURRENTMODE != 4);
//Global Status Register verify RUN0 Current mode
}
//*********IRQ***********//
void
Interrup_Enable(
void
)
{
INTC.CPR.B.PRI = 0; 
// Lower INTC's current priority
asm(
''wrteei 1''
); 
//Enable external interrupt ================>>> PROBLEM THIS LINE
}
void
PIT_0_Handler(
void
)
{
PIT.CH[0].TFLG.B.TIF = 1;
SIU.GPDO[90].B.PDO ^= 1;
}

Note: ivor.s and vector.s copy my project folder. Thanks. Best Regards, Orhan YILMAZ

    Posted on November 14, 2014 at 13:52 Hello Orhan , Do you want enable PIT 0 Channel handler ? if yes , you have to update your application and use the vector59 (Channel PIT 0) your vector59 handler is already defined in hal_lld.c. if you want to customize it stub ''hal_lld.c '' by using PATCH MODE FEATURE in SPC5Studio 3.3 Example Code hal_lld.c : 

    /**
* @brief PIT channel 0 interrupt handler.
*
* @isr
*/
#if 0
OSAL_IRQ_HANDLER(vector59) {
OSAL_IRQ_PROLOGUE();
osalSysLockFromISR();
osalOsTimerHandlerI();
osalSysUnlockFromISR();
/* Resets the PIT channel 0 IRQ flag.*/
PIT.CH[0].TFLG.R = 1;
OSAL_IRQ_EPILOGUE();
}
#endif

    Example Code main.c (cf below) V2.0: you can see the LED is blinking when the interruption PIT0 happenned 

    //Orhan YILMAZ v2.0 (Updated by Erwan)

typedef
