mbed_official 87:085cde657901 12 ==============================================================================
mbed_official 87:085cde657901 13 ##### How to use this driver #####
mbed_official 87:085cde657901 14 ==============================================================================
mbed_official 87:085cde657901 15 [..]
mbed_official 87:085cde657901 16 This driver is a generic layered driver which contains a set of APIs used to
mbed_official 87:085cde657901 17 control NAND flash memories. It uses the FMC/FSMC layer functions to interface
mbed_official 87:085cde657901 18 with NAND devices. This driver is used as follows:
mbed_official 87:085cde657901 19
mbed_official 87:085cde657901 20 (+) NAND flash memory configuration sequence using the function HAL_NAND_Init()
mbed_official 87:085cde657901 21 with control and timing parameters for both common and attribute spaces.
mbed_official 87:085cde657901 22
mbed_official 87:085cde657901 23 (+) Read NAND flash memory maker and device IDs using the function
mbed_official 87:085cde657901 24 HAL_NAND_Read_ID(). The read information is stored in the NAND_ID_TypeDef
mbed_official 87:085cde657901 25 structure declared by the function caller.
mbed_official 87:085cde657901 26
mbed_official 87:085cde657901 27 (+) Access NAND flash memory by read/write operations using the functions
mbed_official 87:085cde657901 28 HAL_NAND_Read_Page()/HAL_NAND_Read_SpareArea(), HAL_NAND_Write_Page()/HAL_NAND_Write_SpareArea()
mbed_official 87:085cde657901 29 to read/write page(s)/spare area(s). These functions use specific device
mbed_official 87:085cde657901 30 information (Block, page size..) predefined by the user in the HAL_NAND_Info_TypeDef
mbed_official 87:085cde657901 31 structure. The read/write address information is contained by the Nand_Address_Typedef
mbed_official 87:085cde657901 32 structure passed as parameter.
mbed_official 87:085cde657901 33
mbed_official 87:085cde657901 34 (+) Perform NAND flash Reset chip operation using the function HAL_NAND_Reset().
mbed_official 87:085cde657901 35
mbed_official 87:085cde657901 36 (+) Perform NAND flash erase block operation using the function HAL_NAND_Erase_Block().
mbed_official 87:085cde657901 37 The erase block address information is contained in the Nand_Address_Typedef
mbed_official 87:085cde657901 38 structure passed as parameter.
mbed_official 87:085cde657901 39
mbed_official 87:085cde657901 40 (+) Read the NAND flash status operation using the function HAL_NAND_Read_Status().
mbed_official 87:085cde657901 41
mbed_official 87:085cde657901 42 (+) You can also control the NAND device by calling the control APIs HAL_NAND_ECC_Enable()/
mbed_official 87:085cde657901 43 HAL_NAND_ECC_Disable() to respectively enable/disable the ECC code correction
mbed_official 87:085cde657901 44 feature or the function HAL_NAND_GetECC() to get the ECC correction code.
mbed_official 87:085cde657901 45
mbed_official 87:085cde657901 46 (+) You can monitor the NAND device HAL state by calling the function
mbed_official 87:085cde657901 47 HAL_NAND_GetState()
mbed_official 87:085cde657901 48
mbed_official 87:085cde657901 49 [..]
mbed_official 87:085cde657901 50 (@) This driver is a set of generic APIs which handle standard NAND flash operations.
mbed_official 87:085cde657901 51 If a NAND flash device contains different operations and/or implementations,
mbed_official 87:085cde657901 52 it should be implemented separately.
