i am new to this kind of platform.
i am enable to erase & write the data to DATA EEPROM memory in STM32F103RBT6 on Keil uVision 3 IDE. Whenever this code is run, the uC freezes & even not work after RESET. Please help me to get out of this problem.
i am using the following code...
FLASH_Unlock();
FLASH_ClearFlag(FLASH_FLAG_BSY | FLASH_FLAG_EOP | FLASH_FLAG_PGERR | FLASH_FLAG_WRPRTERR);
while(FLASHStatus != FLASH_COMPLETE)
FLASHStatus = FLASH_ErasePage(FLASH_Start_Address);
while(FLASHStatus != FLASH_COMPLETE)
FLASHStatus = FLASH_ProgramHalfWord(FLASH_Start_Address, 0xABAB);
FLASH_Status FLASH_ErasePage(u32 Page_Address)
{
FLASH_Status status = FLASH_COMPLETE;
/* Check the parameters */
assert(IS_FLASH_ADDRESS(Page_Address));
/* Wait for last operation to be completed */
status = FLASH_WaitForLastOperation(EraseTimeout);
if(status == FLASH_COMPLETE)
{
/* if the previous operation is completed, proceed to erase the page */
FLASH->CR|= CR_PER_Set;
FLASH->AR = Page_Address;
FLASH->CR|= CR_STRT_Set;
/* Wait for last operation to be completed */
status = FLASH_WaitForLastOperation(EraseTimeout);
if(status != FLASH_BUSY)
{
/* if the erase operation is completed, disable the PER Bit */
FLASH->CR &= CR_PER_Reset;
}
}
/* Return the Erase Status */
return status;
}
FLASH_Status FLASH_ProgramHalfWord(u32 Address, u16 Data)
{
FLASH_Status status = FLASH_COMPLETE;
/* Check the parameters */
assert(IS_FLASH_ADDRESS(Address));
/* Wait for last operation to be completed */
status = FLASH_WaitForLastOperation(ProgramTimeout);
if(status == FLASH_COMPLETE)
{
/* if the previous operation is completed, proceed to program the new data */
FLASH->CR |= CR_PG_Set;
*(vu16*)Address = Data;
/* Wait for last operation to be completed */
status = FLASH_WaitForLastOperation(ProgramTimeout);
if(status != FLASH_BUSY)
{
/* if the program operation is completed, disable the PG Bit */
FLASH->CR &= CR_PG_Reset;
}
}
/* Return the Program Status */
return status;
}
