When I try to erase a flash sector in MKE02Z64VLD4,the core lockup reset is occured(the LOCKUP bit in SIM->SRSID is set).
the FTMRH registers config as:
| FTMRH->FCLKDIV = 0x0f; | //15.6~16.6MHz |
| FTMRH->FCNFG = 0x00; | |
| FTMRH->FERCNFG = 0x00; | |
| | |
and the following functions for erasing a flash sector:
bool FlashPreCheck(void)
{
if((FTMRH->FCLKDIV & FTMRH_FCLKDIV_FDIV_MASK) != 0x0f){
if((FTMRH->FCLKDIV & FTMRH_FCLKDIV_FDIVLCK_MASK) != 0){
NVIC_SystemReset();
}
else{
if((FTMRH->FSTAT & FTMRH_FSTAT_CCIF_MASK) != 0){
FTMRH->FCLKDIV = 0x0f;
}
}
return FALSE;
}
if((FTMRH->FSTAT & FTMRH_FSTAT_CCIF_MASK) == 0){
return FALSE;
}
if((FTMRH->FSTAT & FTMRH_FSTAT_ACCERR_MASK) != 0){
FTMRH->FSTAT |= FTMRH_FSTAT_ACCERR_MASK;
}
if((FTMRH->FSTAT & FTMRH_FSTAT_FPVIOL_MASK) != 0){
FTMRH->FSTAT |= FTMRH_FSTAT_FPVIOL_MASK;
}
__disable_irq();
WDOG->CNT = 0x02A6;
WDOG->CNT = 0x80B4;
__enable_irq();
return TRUE;
}
bool FlashEraseSector(u32 addr)
{
u32 saddr;
if(!FlashPreCheck())return FALSE;
saddr = addr;
__disable_irq();
FTMRH->FCCOBIX = 0;
FTMRH->FCCOBHI = 0x0a;
FTMRH->FCCOBLO = (u8)(saddr >> 16);
FTMRH->FCCOBIX = 1;
FTMRH->FCCOBHI = (u8)(saddr >> 8);
FTMRH->FCCOBLO = (u8)(saddr >> 0);
FTMRH->FSTAT |= FTMRH_FSTAT_CCIF_MASK;
while((FTMRH->FSTAT & FTMRH_FSTAT_CCIF_MASK) == 0);
__enable_irq();
if((FTMRH->FSTAT & FTMRH_FSTAT_MGSTAT_MASK) != 0)return FALSE;
return TRUE;
}
Is anyone can help me?
