Riverdi SDMMC1 FR_NOT_READY error

 I am encountering the FR_NOT_READY and FR_INVALID_OBJECT error when trying to mount the SD card and write a file in RVT101HVSFWCA0 Riverdi display. Could you please advise on how to resolve these issues?

Hello,

According to the examples provided under https://github.com/STMicroelectronics/STM32CubeH7/blob/master/Projects/STM32H745I-DISCO/Applications/FatFs/FatFs_Shared_Device/CM7/Src/main.c

I don't see that you linked the driver using  FATFS_LinkDriver().

 

  if(FATFS_LinkDriver(&MMC_Driver, MMCPath) == 0)
  {
    /* ..... Some code before */
    FS_FileOperations();
  }
}

static void FS_FileOperations(void)
{
  FRESULT res;
  uint32_t byteswritten, bytesread;

  /* Register the file system object to the FatFs module */
  if(f_mount(&MMCFatFs, (TCHAR const*)MMCPath, 0) != FR_OK)
  {
    goto error;
  }
 /* Some code after ... */

I reviewed the example you provided and corrected my code. The MX_FATFS_Init() function is executed before the StartCARDTask() function. Now I can mount the SD card but I still have the same error when using f_open() or f_write ().

Hello,

Please use </> button to show your code instead of sharing a screenshots of it.

What errors you get for these APIs?

What if you use the same example (as it is) from what I posted and adapt it to your Hardware (clocks+IOs)? do you get the same behavior?

This is my code, I also tried your example and reconfigured the hardware but I still have the same error

If you tried the example as it is and didn't work, you need to check your SD card: it could be corrupted or not compatible.

I am using a type 10 SD card (10MB/s), which one do you recommend?
