/** ****************************************************************************** * @file stm32f4xx_hal_nand.c * @author MCD Application Team * @brief NAND HAL module driver. * This file provides a generic firmware to drive NAND memories mounted * as external device. * @verbatim ============================================================================== ##### How to use this driver ##### ============================================================================== [..] This driver is a generic layered driver which contains a set of APIs used to control NAND flash memories. 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_8b()/HAL_NAND_Read_SpareArea_8b(), HAL_NAND_Write_Page_8b()/HAL_NAND_Write_SpareArea_8b(), HAL_NAND_Read_Page_16b()/HAL_NAND_Read_SpareArea_16b(), HAL_NAND_Write_Page_16b()/HAL_NAND_Write_SpareArea_16b() 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) 2017 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.
