User NOTES
|
|
1. How To use this driver:
|
|
--------------------------
|
|
- This driver is used to drive the NAND512W3A2CN6E NAND flash external memory mounted
|
|
on STM3210E-EVAL evaluation board.
|
|
- This driver does not need a specific component driver for the NAND device
|
|
to be included with.
|
|
|
|
2. Driver description:
|
|
---------------------
|
|
+ Initialization steps:
|
|
o Initialize the NAND external memory using the BSP_NAND_Init() function. This
|
|
function includes the MSP layer hardware resources initialization and the
|
|
FMC controller configuration to interface with the external NAND memory.
|
|
|
|
+ NAND flash operations
|
|
o NAND external memory can be accessed with read/write operations once it is
|
|
initialized.
|
|
Read/write operation can be performed with AHB access using the functions
|
|
BSP_NAND_ReadData()/BSP_NAND_WriteData(). The BSP_NAND_WriteData() performs write operation
|
|
of an amount of data by unit (halfword).
|
|
o The function BSP_NAND_Read_ID() returns the chip IDs stored in the structure
|
|
"NAND_IDTypeDef". (see the NAND IDs in the memory data sheet)
|
|
o Perform erase block operation using the function BSP_NAND_Erase_Block() and by
|
|
specifying the block address.
