[STM32H573IT] I can't FATFS in CubeMX.

[kadekade]

Hi Everyone,

I need your help.

I use STM32H573VIT but I can't FATFS in CUBEMX.

I checked FILEX, SD interface. But CUBEIDE say fatfs.h : No such file or directory.

Please help me out..

Thanks,

Hello @kadekade 

Let me thank you for your posting.

I created a project with STM32CubeMX 6.17 [STM32H573VIT6], and the issue was not reproduced by my side.

The compilation completed without any errors.

For more investigation, I suggest please that you provide your Ioc.File.

Thanks.

Hi,

>but I can't FATFS

Right, here no fatfs , you have to use filex , as you selected in Cube.

mount drive ->

/* Open the SD disk driver */
  sd_status =  fx_media_open(&sdio_disk, FX_SD_VOLUME_NAME, fx_stm32_sd_driver, (VOID *)FX_NULL, (VOID *) fx_sd_media_memory, sizeof(fx_sd_media_memory));

Dear Mahmoud,

I appreciate your help. I'm sorry to reply late.

I attatched my ioc file. My settings is slightly defferent with your settings(SDMMC1_D0)

yours : SDMMC1_D0 PB13

me : SDMMC1_D0 PC8

I going to try testing with your ioc file.

Thanks,

Hello @kadekade 

Further to your comment, I tested again with the Ioc.File provided through the attachment and the build was finished without any errors.

I will be waiting for your feedback.

Thanks.

Thank you so much.

Yes...Right

I figured out what my mistake was. 

To do microSD, I tried to merge OLD FATFS source codes. so I want to see FATFS in CUBEMX.

But FATFS is replaced by FILEX.

Finally, I made new codes with FILEX below, ( I need your help once more..)

(example codes from somewhere on web.)

MX_GPIO_Init();
MX_SDMMC1_SD_Init();
MX_FileX_Init();

 FX_MEDIA   sd_disk;

  UINT   status;

  CHAR   *write_buffer = "Hello STM32 FileX!";

  unsigned char media_memory[256];

  status = fx_media_open(&sd_disk, "SD_CARD", fx_stm32_sd_driver,  0, media_memory, sizeof(media_memory));

      /* 2. 占쏙옙占쏙옙 占쏙옙占쏙옙 占쏙옙 占쏙옙占쏙옙 占쏙옙占쏙옙  (in korean)*/

    FX_FILE my_file;

    fx_file_create(&sd_disk, "test.txt");

    fx_file_open(&sd_disk, &my_file, "test.txt", FX_OPEN_FOR_WRITE);

    fx_file_write(&my_file, "Hello FileX!", 12);

    fx_file_close(&my_file);

    /* 3. 占쏙옙占쏙옙占쏙옙占?占쏙옙占쏙옙 占쏙옙체占쏙옙 占쏙옙占쏙옙 */

    fx_media_flush(&sd_disk);

Unfortunately, I could't write [test.txt] in microSD and went to HARD FAULTS.

I would appreciate your help once more...

Thanks,

BR

I found out why it doesn't work.

I should setting memory bigger than sector sizes(ex:4096).

So. Not unsigned char media_memory[256]

is "unsigned char media_memory[4096 or more]"

Thanks,

BR
