mbed_official 133:d4dda5c437f0 12 ==============================================================================
mbed_official 133:d4dda5c437f0 13 ##### How to use this driver #####
mbed_official 133:d4dda5c437f0 14 ==============================================================================
mbed_official 133:d4dda5c437f0 15 [..]
mbed_official 133:d4dda5c437f0 16 This driver is a generic layered driver which contains a set of APIs used to
mbed_official 133:d4dda5c437f0 17 control NAND flash memories. It uses the FMC/FSMC layer functions to interface
mbed_official 133:d4dda5c437f0 18 with NAND devices. This driver is used as follows:
mbed_official 133:d4dda5c437f0 19
mbed_official 133:d4dda5c437f0 20 (+) NAND flash memory configuration sequence using the function HAL_NAND_Init()
mbed_official 133:d4dda5c437f0 21 with control and timing parameters for both common and attribute spaces.
mbed_official 133:d4dda5c437f0 22
mbed_official 133:d4dda5c437f0 23 (+) Read NAND flash memory maker and device IDs using the function
mbed_official 133:d4dda5c437f0 24 HAL_NAND_Read_ID(). The read information is stored in the NAND_ID_TypeDef
mbed_official 133:d4dda5c437f0 25 structure declared by the function caller.
mbed_official 133:d4dda5c437f0 26
mbed_official 133:d4dda5c437f0 27 (+) Access NAND flash memory by read/write operations using the functions
mbed_official 133:d4dda5c437f0 28 HAL_NAND_Read_Page()/HAL_NAND_Read_SpareArea(), HAL_NAND_Write_Page()/HAL_NAND_Write_SpareArea()
mbed_official 133:d4dda5c437f0 29 to read/write page(s)/spare area(s). These functions use specific device
mbed_official 133:d4dda5c437f0 30 information (Block, page size..) predefined by the user in the HAL_NAND_Info_TypeDef
mbed_official 133:d4dda5c437f0 31 structure. The read/write address information is contained by the Nand_Address_Typedef
mbed_official 133:d4dda5c437f0 32 structure passed as parameter.
mbed_official 133:d4dda5c437f0 33
mbed_official 133:d4dda5c437f0 34 (+) Perform NAND flash Reset chip operation using the function HAL_NAND_Reset().
mbed_official 133:d4dda5c437f0 35
mbed_official 133:d4dda5c437f0 36 (+) Perform NAND flash erase block operation using the function HAL_NAND_Erase_Block().
mbed_official 133:d4dda5c437f0 37 The erase block address information is contained in the Nand_Address_Typedef
mbed_official 133:d4dda5c437f0 38 structure passed as parameter.
mbed_official 133:d4dda5c437f0 39
mbed_official 133:d4dda5c437f0 40 (+) Read the NAND flash status operation using the function HAL_NAND_Read_Status().
mbed_official 133:d4dda5c437f0 41
mbed_official 133:d4dda5c437f0 42 (+) You can also control the NAND device by calling the control APIs HAL_NAND_ECC_Enable()/
mbed_official 133:d4dda5c437f0 43 HAL_NAND_ECC_Disable() to respectively enable/disable the ECC code correction
mbed_official 133:d4dda5c437f0 44 feature or the function HAL_NAND_GetECC() to get the ECC correction code.
mbed_official 133:d4dda5c437f0 45
mbed_official 133:d4dda5c437f0 46 (+) You can monitor the NAND device HAL state by calling the function
mbed_official 133:d4dda5c437f0 47 HAL_NAND_GetState()
mbed_official 133:d4dda5c437f0 48
mbed_official 133:d4dda5c437f0 49 [..]
mbed_official 133:d4dda5c437f0 50 (@) This driver is a set of generic APIs which handle standard NAND flash operations.
mbed_official 133:d4dda5c437f0 51 If a NAND flash device contains different operations and/or implementations,
mbed_official 133:d4dda5c437f0 52 it should be implemented separately.
