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.
Terry
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
