NUCLEO BOARD NOD FLASH DRIVE

[yang hong]

Hello,

I am using Nucleo board, every time when I connect usb port on debuger side, my pc popups a windows to tell me "NOD_F439ZI" is connected, so I can use file explorer to view the file on it. For example, NUCLEO-F439ZI has 6MB space, does anybody knows what it is for? how to use it? is it possible to use it to update firmware to controller? whether it is possible to send log from main controller to this space?

Regards,

It doesn't provide two-conduit or a real file system. It is a faux MSC Device that presents like a FAT Volume, sufficient to allow you to drag and drop a binary, and that gets translated to a erase/write of the target STM32's Internal Flash.

It can't be used to update the ST-LINK's firmware.

You can output data via the ST-LINK VCP via one of the Target's UARTs. Perhaps the SWO/SWV data channel could be captured
