Hello, I am using timer 3 Module configured as full width periodic.
void ConfigureTimer(void)
{
unsigned long ui32Period;
//cfg timer 3a to hold 50 ms value, enable interrupt
//periodic operation so that it reloads automatically
SysCtlPeripheralEnable( SYSCTL_PERIPH_TIMER3 );
SysCtlDelay(6);
ui32Period = (740740);
TimerConfigure(TIMER3_BASE, TIMER_CFG_PERIODIC);
TimerLoadSet(TIMER3_BASE, TIMER_A, ui32Period);
TimerIntEnable(TIMER3_BASE, TIMER_TIMA_TIMEOUT);
TimerEnable(TIMER3_BASE,TIMER_A);
}
The timer works perfectly when value is set at 60000~ approximately, but when set to 740740 (50 ms delay at 14.8 mHZ Clock), there is the following error once interrupt handler runs.
FSR = 0x0004
HFSR = 0x40000000
DFSR = 0x0000000a
MMAR = 0xe000ed34
BFAR = 0xe000ed38
AFSR = 0x00000000
Terminating execution...
What could be the problem here? I have configured timer for full width periodic as indicated in multiple examples.
Even in the TivaWare Library, the timer load set (only use Timer A for full width) is set correctly. It appears that the only problem is with timer load set, because when it is set lower (30-60,000) timer works.
Any guidance would be great!
