Table 44. FSMC_NAND_WriteSpareArea

Function name

FSMC_NAND_WriteSpareArea.

Prototype

uint32_t FSMC_NAND_WriteSpareArea(uint8_t *pBuffer,

NAND_ADDRESS Address,

uint32_t NumSpareAreaTowrite)

Behavior description

Writes spare area information for specified page addresses.

Input parameter

pBuffer: pointer on the Buffer containing data to be written.

Address: First page address.

NumSpareAreaTowrite: Number of Spare Area to write.

Output parameter

New status of the NAND operation. This parameter can be:

– NAND_TIMEOUT_ERROR: when the previous operation generate a

Timeout error.

– NAND_READY: when memory is ready for the next operation

New status of the increment address operation. It can be:

– NAND_VALID_ADDRESS: When the new address is valid.

– NAND_INVALID_ADDRESS: When the new address is invalid.

Table 45. FSMC_NAND_ReadSpareArea

Function name

FSMC_NAND_ReadSpareArea.

Prototype

uint32_t FSMC_NAND_ReadSpareArea(uint8_t *pBuffer,

NAND_ADDRESS Address,

uint32_t NumSpareAreaToRead)

Behavior description

Reads the spare area information from the specified page addresses.

Input parameter

pBuffer: pointer on the Buffer to fill.

Address: First page address.

NumSpareAreaToRead: Number of Spare Area to read.

Output parameter

New status of the NAND operation. This parameter can be:

– NAND_TIMEOUT_ERROR: when the previous operation generated a

Timeout error.

– NAND_READY: when memory is ready for the next operation

New status of the increment address operation. It can be:

– NAND_VALID_ADDRESS: When the new address is valid.

– NAND_INVALID_ADDRESS: When the new address is invalid.

Table 46. FSMC_NAND_EraseBlock

Function name

FSMC_NAND_EraseBlock.

Prototype

uint32_t FSMC_NAND_EraseBlock(NAND_ADDRESS Address)

Behavior description

Erases complete block from NAND FLASH.

Input parameter

Address: Any address into block to be erased.

Output parameter

New status of the NAND operation. This parameter can be:

– NAND_TIMEOUT_ERROR: when the previous operation generate a

Timeout error.

– NAND_READY: when memory is ready for the next operation.
