Hello,
In the SDK for RT1xxx I find the meddleware related to FatFs. It is hosted on github here
https://github.com/nxp-mcuxpresso/fatfs/tree/mcux_release
In there I find some directories that implement abstraction for sd, ram disk, mmc, etc.
Can you explain the fsl_usb_disk directory? Where is the filesystem archived? In ram like the ram disk?
best regards
Max

Hi @mastupristi ,
Thanks for your interest in NXP MIMXRT series!
In the RT series SDK, the fsl_usb_disk is the abstraction layer in the FatFs file system for USB storage devices. Instead of being stored in RAM, the file system is stored on an external storage device connected via USB, such as a USB flash drive or hard disk. When you use `fsl_usb_disk`, it manages the file system on the USB storage device.
Best regards,
Gavin
Hi @Gavin_Jia ,
let me see if I have understood correctly: in this scenario, the RT1xxx microcontroller is usb host, right? And the device is a usb storage stick, right?
best regards
