Function Documentation

HAL_StatusTypeDef HAL_FLASHEx_OBErase ( void   )

Erases the FLASH option bytes.

Note:
This functions erases all option bytes except the Read protection (RDP). The function HAL_FLASH_Unlock() should be called before to unlock the FLASH interface The function HAL_FLASH_OB_Unlock() should be called before to unlock the options bytes The function HAL_FLASH_OB_Launch() should be called after to force the reload of the options bytes (system reset will occur)
Return values:
HALstatus

Definition at line 414 of file stm32f1xx_hal_flash_ex.c.

void HAL_FLASHEx_OBGetConfig ( FLASH_OBProgramInitTypeDef *  pOBInit )

Get the Option byte configuration.

Parameters:
pOBInitpointer to an FLASH_OBInitStruct structure that contains the configuration information for the programming.
Return values:
None

Definition at line 544 of file stm32f1xx_hal_flash_ex.c.

uint32_t HAL_FLASHEx_OBGetUserData ( uint32_t  DATAAdress )

Get the Option byte user data.

Parameters:
DATAAdressAddress of the option byte DATA This parameter can be one of the following values:

  • OB_DATA_ADDRESS_DATA0
  • OB_DATA_ADDRESS_DATA1
Return values:
Valueprogrammed in USER data

Definition at line 566 of file stm32f1xx_hal_flash_ex.c.

HAL_StatusTypeDef HAL_FLASHEx_OBProgram ( FLASH_OBProgramInitTypeDef *  pOBInit )

Program option bytes.

Note:
The function HAL_FLASH_Unlock() should be called before to unlock the FLASH interface The function HAL_FLASH_OB_Unlock() should be called before to unlock the options bytes The function HAL_FLASH_OB_Launch() should be called after to force the reload of the options bytes (system reset will occur)
Parameters:
pOBInitpointer to an FLASH_OBInitStruct structure that contains the configuration information for the programming.
Return values:
HAL_StatusTypeDefHAL Status
