HAL_StatusTypeDef HAL_NOR_Erase_Block ( NOR_HandleTypeDef *  hnor,
uint32_t  BlockAddress,
uint32_t  Address 
)

Erase the specified block of the NOR memory.

Parameters:
hnor,:pointer to a NOR_HandleTypeDef structure that contains the configuration information for NOR module.
BlockAddress: Block to erase address
Address,:Device address
Return values:
HALstatus

Definition at line 700 of file stm32l4xx_hal_nor.c.

HAL_StatusTypeDef HAL_NOR_Erase_Chip ( NOR_HandleTypeDef *  hnor,
uint32_t  Address 
)

Erase the entire NOR chip.

Parameters:
hnor,:pointer to a NOR_HandleTypeDef structure that contains the configuration information for NOR module.
Address: Device address
Return values:
HALstatus

Definition at line 759 of file stm32l4xx_hal_nor.c.

HAL_StatusTypeDef HAL_NOR_Program ( NOR_HandleTypeDef *  hnor,
uint32_t *  pAddress,
uint16_t *  pData 
)

Program data to NOR memory.

Parameters:
hnor,:pointer to a NOR_HandleTypeDef structure that contains the configuration information for NOR module.
pAddress,:Device address
pData: pointer to the data to write
Return values:

)

Write a half-word buffer to the FMC NOR memory.

This function must be used only with S29GL128P NOR memory.

Parameters:
hnor,:pointer to a NOR_HandleTypeDef structure that contains the configuration information for NOR module.
uwAddress,:NOR memory internal address from which the data
Note:
Some NOR memory need Address aligned to xx bytes (can be aligned to 64 bytes boundary for example).
Parameters:
pData,:pointer to source data buffer.
uwBufferSize,:number of Half words to write.
Note:
The maximum buffer size allowed is NOR memory dependent (can be 64 Bytes max for example).
