Hi,

According with the reference manual the LPC1788 supports SD card interface that also supports MMC cards only.
So, this device does not support eMMC.


Have a great day,

Soledad

Hi,

    eMMC and MMC card Hardware interface is same ,different is driver software ,

 

   and MMC card drive  eMMC driver  The difference is very small

 

   Can software not support it?

I see

In fs_mci.c function :

/**
* @brief Read card configuration and fill structure CardConfig.
*
* @param None
* @retval TRUE or FALSE.
*/
Bool mci_read_configuration (void)

/* Select Card */
if(MCI_Cmd_SelectCard() != MCI_FUNC_OK) /* CMD7 tese same card reader */
{
break;
}

//  In this line add achieve:

EmmcReadExtCsd  

and according to ExtCsd message set same CardInfo

Can you help me?

thank you
