It uses the FMC/FSMC layer functions to interface + with NAND devices. This driver is used as follows: + + (+) NAND flash memory configuration sequence using the function HAL_NAND_Init() + with control and timing parameters for both common and attribute spaces. + + (+) Read NAND flash memory maker and device IDs using the function + HAL_NAND_Read_ID(). The read information is stored in the NAND_ID_TypeDef + structure declared by the function caller. + + (+) Access NAND flash memory by read/write operations using the functions + HAL_NAND_Read_Page()/HAL_NAND_Read_SpareArea(), HAL_NAND_Write_Page()/HAL_NAND_Write_SpareArea() + to read/write page(s)/spare area(s). These functions use specific device + information (Block, page size..) predefined by the user in the HAL_NAND_Info_TypeDef + structure. The read/write address information is contained by the Nand_Address_Typedef + structure passed as parameter. + + (+) Perform NAND flash Reset chip operation using the function HAL_NAND_Reset(). + + (+) Perform NAND flash erase block operation using the function HAL_NAND_Erase_Block(). + The erase block address information is contained in the Nand_Address_Typedef + structure passed as parameter. + + (+) Read the NAND flash status operation using the function HAL_NAND_Read_Status(). + + (+) You can also control the NAND device by calling the control APIs HAL_NAND_ECC_Enable()/ + HAL_NAND_ECC_Disable() to respectively enable/disable the ECC code correction + feature or the function HAL_NAND_GetECC() to get the ECC correction code. + + (+) You can monitor the NAND device HAL state by calling the function + HAL_NAND_GetState() + + [..] + (@) This driver is a set of generic APIs which handle standard NAND flash operations. + If a NAND flash device contains different operations and/or implementations, + it should be implemented separately. + + @endverbatim + ****************************************************************************** + * @attention + * + * <h2><center>© COPYRIGHT(c) 2015 STMicroelectronics</center></h2> + * + * Redistribution and use in source and binary forms, with or without modification, + * are permitted provided that the following conditions are met: + * 1.
