Everybody,

How to use USB as Mass Storage Class ?

This question is related with SDIO I had done intiating,

Which configuration file do  I need to change ?

I can see drive E on my computer now, but can not read the content yet,

Anyone knows ?

Thanks

As per FatFs, the SDIO layer must present coherent data from the media.

I got SDIO and FATFs running, then put USB as MSC on STM32CubeMX, what

else do I need to connect them ?

Is it related with this function ? SD Init must be here ?

In the first order the GET CAPACITY and READ functionality of the MSC are critical to Windows successfully mounting the media.

6.2 Mass storage class

6.2.1 Mass storage class implementation

UM1734 page 32, how to implement that with STM32CubeMX ??

Can I call like this in usbd_storage_if.c ?

Any ideas ?

&sharpinclude 'bsp_driver_sd.h'

/*******************************************************************************

• Function Name : STORAGE_Init_FS

• Description :

• Input : None.

• Output : None.

• Return : None.

*******************************************************************************/

int8_t STORAGE_Init_FS (uint8_t lun)

{

/* USER CODE BEGIN 2 */

BSP_SD_Init();

return (USBD_OK);

/* USER CODE END 2 */

}

Aren't them some examples you can analyze? I really can't hold your hand doing USB/HAL related stuff, I don't learn stuff by asking millions of question, I review available information/examples from all available sources.
