HardFault_Handler occure when Timer interrupt enableing

ali micro

Hi
I am using LPC1788 evaluation kit (OEM509 board) and I need to use timer interrupt and CMSIS RTX OS at the same time.

here is a part of source code:

TIM_ConfigStruct.PrescaleOption=TIM_PRESCALE_USVAL;
TIM_ConfigStruct.PrescaleValue=100;
TIM_MatchConfigStruct.IntOnMatch=TRUE;
TIM_MatchConfigStruct.MatchChannel=0;
TIM_MatchConfigStruct.ResetOnMatch=TRUE;
TIM_MatchConfigStruct.StopOnMatch=FALSE;
TIM_MatchConfigStruct.MatchValue=10000;
TIM_Init(LPC_TIM0,TIM_TIMER_MODE,&TIM_ConfigStruct);
TIM_ConfigMatch(LPC_TIM0,&TIM_MatchConfigStruct);
NVIC_SetPriority(TIMER0_IRQ0,((0x01<<3)|0x01));
NVIC_EnableIRQ(TIMER0_IRQn);
TIM_CMD(LPC_TIM0,ENABLE);

when this code runnig without RTX is fully functional but when I added RTX to project HardFault_Handler will occure at the end of TIM_ConfigMatch (when return).

I've checked it with privilege and unprivilege mode but doesn't effect.

    Check the Bus Fault register. Is the PRECISERR bit set (D1 bit)??
    If yes, than check the address (faulting address) in the Bus_Fault_Addr Register (BFAR).

    Study the memory map in the data sheet. Find the address is in which peripheral register-space (May be, the Timer is not powered-on from PCONP register).
