| mbed_official | 610:813dcc80987e | 13 | ##### How to use this driver ##### |
| mbed_official | 610:813dcc80987e | 14 | ============================================================================== |
| mbed_official | 610:813dcc80987e | 15 | [..] |
| mbed_official | 610:813dcc80987e | 16 | This driver is a generic layered driver which contains a set of APIs used to |
| mbed_official | 610:813dcc80987e | 17 | control NAND flash memories. It uses the FMC layer functions to interface |
| mbed_official | 610:813dcc80987e | 18 | with NAND devices. This driver is used as follows: |
| mbed_official | 610:813dcc80987e | 19 | |
| mbed_official | 610:813dcc80987e | 20 | (+) NAND flash memory configuration sequence using the function HAL_NAND_Init() |
| mbed_official | 610:813dcc80987e | 21 | with control and timing parameters for both common and attribute spaces. |
| mbed_official | 610:813dcc80987e | 22 | |
| mbed_official | 610:813dcc80987e | 23 | (+) Read NAND flash memory maker and device IDs using the function |
| mbed_official | 610:813dcc80987e | 24 | HAL_NAND_Read_ID(). The read information is stored in the NAND_ID_TypeDef |
| mbed_official | 610:813dcc80987e | 25 | structure declared by the function caller. |
| mbed_official | 610:813dcc80987e | 26 | |
| mbed_official | 610:813dcc80987e | 27 | (+) Access NAND flash memory by read/write operations using the functions |
| mbed_official | 610:813dcc80987e | 28 | HAL_NAND_Read_Page()/HAL_NAND_Read_SpareArea(), HAL_NAND_Write_Page()/HAL_NAND_Write_SpareArea() |
| mbed_official | 610:813dcc80987e | 29 | to read/write page(s)/spare area(s). These functions use specific device |
| mbed_official | 610:813dcc80987e | 30 | information (Block, page size..) predefined by the user in the HAL_NAND_Info_TypeDef |
| mbed_official | 610:813dcc80987e | 31 | structure. The read/write address information is contained by the Nand_Address_Typedef |
| mbed_official | 610:813dcc80987e | 32 | structure passed as parameter. |
| mbed_official | 610:813dcc80987e | 33 | |
| mbed_official | 610:813dcc80987e | 34 | (+) Perform NAND flash Reset chip operation using the function HAL_NAND_Reset(). |
| mbed_official | 610:813dcc80987e | 35 | |
| mbed_official | 610:813dcc80987e | 36 | (+) Perform NAND flash erase block operation using the function HAL_NAND_Erase_Block(). |
| mbed_official | 610:813dcc80987e | 37 | The erase block address information is contained in the Nand_Address_Typedef |
| mbed_official | 610:813dcc80987e | 38 | structure passed as parameter. |
| mbed_official | 610:813dcc80987e | 39 | |
| mbed_official | 610:813dcc80987e | 40 | (+) Read the NAND flash status operation using the function HAL_NAND_Read_Status(). |
| mbed_official | 610:813dcc80987e | 41 | |
| mbed_official | 610:813dcc80987e | 42 | (+) You can also control the NAND device by calling the control APIs HAL_NAND_ECC_Enable()/ |
| mbed_official | 610:813dcc80987e | 43 | HAL_NAND_ECC_Disable() to respectively enable/disable the ECC code correction |
| mbed_official | 610:813dcc80987e | 44 | feature or the function HAL_NAND_GetECC() to get the ECC correction code. |
| mbed_official | 610:813dcc80987e | 45 | |
| mbed_official | 610:813dcc80987e | 46 | (+) You can monitor the NAND device HAL state by calling the function |
| mbed_official | 610:813dcc80987e | 47 | HAL_NAND_GetState() |
| mbed_official | 610:813dcc80987e | 48 | |
| mbed_official | 610:813dcc80987e | 49 | [..] |
| mbed_official | 610:813dcc80987e | 50 | (@) This driver is a set of generic APIs which handle standard NAND flash operations. |
| mbed_official | 610:813dcc80987e | 51 | If a NAND flash device contains different operations and/or implementations, |
| mbed_official | 610:813dcc80987e | 52 | it should be implemented separately. |
