Good morning,
I would like to implement Fatfs to communicate with a sd card in the core M4 and with a usb mass storage device in the core M7. In Cube Mx environment I'm able to initialize what I need, obtaining a fatfs M4 initialized to communicate with sd card and a fatfs M7 initialized to communicate with a usb mass storage device. Pratically this solution doesn't work (The devices are not recognized: the sd card is correctly mounted just one time and then it is not recognized while the usb is never recognized) but, when I keep everything together in the same core, fatfs M7 (usb mass storage+sd card) works perfectly. Could you tell me If it's possible to implement fatfs in the following way: fatfs M4 (sd card) and fatfs M7 (usb mass storage)? And considering that I need to create files inside sd card and write data to them in core m4 and sending these files from sd to usb in m7, are there some variables (like sd file path etc) that I need eventually to put in shared memory ?
Let me know and thanks for your time!
Luca
