I am using the Luckfox Pico Pi A W (RV1106G3) board and would like to know if it is possible to access the board’s internal eMMC and external microSD card from a PC through USB.

My goal is for the board(in host mode) to appear as a USB Mass Storage device when connected to a computer.

Is this supported on this board? If yes, what is the recommended method to implement it (USB Gadget / Mass Storage)?

Thank you.

Please conduct development based on a thorough understanding of the Gadget mechanism. This function is a generic feature of the Linux system.
Be sure to remove the default system files /etc/init.d/S50usbdevice and /etc/init.d/S99usb0config to prevent the ADB function from occupying high-speed EP endpoints, which would cause the UMS function to fail to enable.
