HAL NAND Config - SpareAreaSize / PageSize values..

[David George]

Hi.

When configuring the HAL_NAND driver you need to set the PageSize and SpareAreaSizes values;

 /* hnand1.Config */

  hnand1.Config.PageSize = 2048;  hnand1.Config.SpareAreaSize = 64;   hnand1.Config.BlockSize = 64;  hnand1.Config.BlockNbr = 1024;  hnand1.Config.PlaneNbr = 1;  hnand1.Config.PlaneSize = 1024;  hnand1.Config.ExtraCommandEnable = ENABLE;

 HAL_NAND_Init(&hnand1, &ComSpaceTiming, &AttSpaceTiming);

Does anyone know if these values are for the

whole device

or just the

page

?

The typedefs in the HAL NAND driver suggest these are large values as they are in kB, so suggesting these are for the whole device. For my device the SpareAreaSize for a page is 64 bytes, so you can't set 0.0625 !!

In stm32f7xx_hal_nand.h:

uint32_t ;      

/*!< NAND memory page (without spare area) size measured in K. bytes */

uint32_t ; 

/*!< NAND memory spare area size measured in K. bytes                */

Thank you!

Kind of found an answer, looked in the actual 'stm32f7xx_hal_nand.h' file in my project and the struct is described differently from the help documentation;

/**

  * @brief  NAND Memory info Structure definition  */ typedef struct{  uint32_t        PageSize;              /*!< NAND memory page (without spare area) size measured in bytes                                               for 8 bits adressing or words for 16 bits addressing             */

  uint32_t        SpareAreaSize;         /*!< NAND memory spare area size measured in bytes

                                              for 8 bits adressing or words for 16 bits addressing             */    uint32_t        BlockSize;             /*!< NAND memory block size measured in number of pages               */

  uint32_t        BlockNbr;              /*!< NAND memory number of total blocks                               */

       uint32_t        PlaneNbr;              /*!< NAND memory number of planes                                     */

  uint32_t        PlaneSize;             /*!< NAND memory zone size measured in number of blocks               */

  FunctionalState ExtraCommandEnable;    /*!< NAND extra command needed for Page reading mode. This

                                              parameter is mandatory for some NAND parts after the read                                               command (NAND_CMD_AREA_TRUE1) and before DATA reading sequence.                                               Example: Toshiba THTH58BYG3S0HBAI6.                                              This parameter could be ENABLE or DISABLE                                              Please check the Read Mode sequnece in the NAND device datasheet */}NAND_DeviceConfigTypeDef;

In which help documentation you find the wrong comment?

Hi.

I

was

looking in '..\STM32Cube_FW_F7_V1.5.0\Drivers\STM32F7xx_HAL_Driver\STM32F756xx_User_Manual.chm', old Cube version.

I now have used '..\STM32Cube_FW_F7_V1.7.0\Drivers\STM32F7xx_HAL_Driver\STM32F756xx_User_Manual.chm' and the description is different.

I assume that's the best to use for the STM32F767NIH device.

The 'hint' inside the FMC NAND Setup dialog in STM32CubeMX however still mentions ' size in K. bytes ' which I think is wrong.

Hi David,

Thanks for your reply.

Using 

STM32F767NIH, STM32F779xx_User_Manual.chm may be the more suitable.

Regarding the comment in CubeMX, I'll report it.

Hi

George.David.002

,

This issue is now fixed in the current CubeMX release.

Please, upgrade with CubeMX4.25 if not already done.
