How to read/write the file system of the flash

Victorheca01 · ‎2024-07-10

Hi, All

when I power on the U575 eval board, the file system of flash chip come out immediately on my computer as the attached picture. My question is how to read/write the file system from MCU of U575 by firmware? Anyone has the experience or any document to show this. Thanks a lot in advance.

What you see as a file system is the so-called mass storage interface on USB, which as a virtual file system provides the connected host with any errors in a text file or can accept BIN or HEX files. This makes it easy to programme an EVAL, NUCLEO or DISCOVERY without having to use programming software.

This virtual file system, which is controlled by the included ST-LINK and not by the target, is otherwise not available to the user.

Does it answer your question?
