你好
请教一下S32K146 的读冲突中断是怎么测试出来的，能否给一个demo code？
我的代码简单测试流程下面回列出来 但是就是无法产生这个读冲突中断，能否帮忙指点一下为啥这样不产生读冲突中断，感谢你的回答
void EraseFlashSector(void)
{
uint32_t address = 0x00008000;
uint32_t flashData = 0 ;
uint32_t i = 0;
uint32_t expectData = 0;
uint32_t FailAddr = 0;
//erase 4KB flash sector (the smallest entity that can be erased)
while((FTFC->FSTAT & FTFC_FSTAT_CCIF_MASK) == 0); // Wait if operation in progress
FTFC->FSTAT = FTFC_FSTAT_ACCERR_MASK | FTFC_FSTAT_FPVIOL_MASK;
FTFC->FCCOB[3] = 0x09; //Erase Flash Sector command (0x09)
FTFC->FCCOB[2] = (address >> 16) & 0xff; //Flash address [23:16]
FTFC->FCCOB[1] = (address >> & 0xff; //Flash address [15:08]
FTFC->FCCOB[0] = address & 0xff; //Flash address [7:0]
FTFC->FSTAT = FTFC_FSTAT_CCIF_MASK; //launch command
while(( FTFC->FSTAT & FTFC_FSTAT_CCIF_MASK) == 0)
{
expectData = 0xFFFFFFFF;
for(i=0; i< 1024; i++)
{
FLASH_DRV_ProgramCheck(&flashSSDConfig, 0x8000+i*4, 4, &expectData, &FailAddr, 1);
}
flashData = *(uint32_t *)(0x8000 + 4);
flashData = *(uint32_t *)(0x8000 + 8);
flashData = *(uint64_t *)(0x8000 + 16);
for(i = 0; i< 1024;i++)
{
flashData = *(uint32_t *)(0x8000 + i*4);
}
}//wait for done
}
int main()
{
/* Enable global interrupt */
INT_SYS_EnableIRQGlobal();
/* interrupt test*/
FTFC->FCNFG |= 0x40;//enable read conflicit interrupt
INT_SYS_EnableIRQ(Read_Collision_IRQn);
EraseFlashSector();
}
