USB-HS storage to NVM with RT102x

[threeboystech]

I'm using an MIMXRT1021 that is required to store USB-HS data (at least 16GB) to NVM storage.

Is there a recommended solution as to what memory and what memory configuration to use?  My thoughts are an eMMC part connected to the USDHC2 peripheral using the 8-pin data interface.

Can someone share an application note link on how to make this connection?

Thanks

Do you have a link to a USB Spec document that will provide details on the supported Callback events supported by the SDK?  Examples on how to detect when a disk operation is started/stopped would be helpful.  Searching NXP for this document has not provided any success.

Hi Terry, 

I am sorry for the late reply. 

There is USB stack documentation detailed within SDK, please take a look to see if it helps you. See the below example

Many thanks for your patience.

Hi Diego

Our solution will not require a SD card, we will be using direct connection to the eMMC.

Thanks for letting me know, Terry.

Hi @threeboystech 

Do you require an eMMC over an SD card? A SD card is another flexible option. 

As you may now we have several MMC examples in our SDK, and most of them are SD card based .For example sdcard_fatfs to see SD card file creating and R/W and  the dev_msc_disk_bm which works as a USB to SD card bridge.

Best regards, 

Diego
