NAND driver firmware modules

Table 42. FSMC_NAND_WriteSmallPage

Function name

FSMC_NAND_WriteSmallPage.

Prototype

uint32_t FSMC_NAND_WriteSmallPage(uint8_t *pBuffer,

NAND_ADDRESS Address,

uint32_t NumPageToWrite)

Behavior description

Writes one or several 512 Bytes Page size.

Input parameter

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

Address: First page address.

NumPageToWrite: Number of page 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 43. FSMC_NAND_ReadSmallPage

Function name

FSMC_NAND_ReadSmallPage.

Prototype

uint32_t FSMC_NAND_ReadSmallPage(uint8_t *pBuffer,

NAND_ADDRESS Address,

uint32_t NumPageToRead)

Behavior description

Sequential read from one or several 512 Bytes Page size.

Input parameter

pBuffer: pointer on the Buffer to fill.

Address: First page address.

NumPageToRead: Number of page to read.

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.
