Hi all,
I'm trying to configure my NUCLEO-H745ZI RAM as Device mass storage, i followed some tutoriels showing how to do this application with CubeMX and Keil IDE but its not working for me. I write my code only in "usbd_storage_if.c" file.

The code compile, load it to flash memory and enter debug mode to run the program.
When i connect the usb connector present on the board to test if the computer will detect it as an usb device mass storage, nothing happen !
Can someone help with this ? Thanks

Not really a CubeMX guy, perhaps there are some MSC SDRAMDISK examples in the Cube H7 HAL directories for one or more of the H7 EVAL or DISCO boards
On the NUCLEO, power/debug by the North End USB, MSC / Device via the South End USB
Make sure you have the pin/usb associations correct for the board, check manual/schematic to be sure.
Use the debugger, check the code is running. For USB instrument the code with output to a serial port so that the code can run in realtime and you can observe what's happening without breakpointing or stopping USB from functioning.
Up vote any posts that you find helpful, it shows what's working..

Thank you Sir for your answer.
I didn't find any MSC RAM examples in Keil IDE using H7 Boards.
But i found out that in debug mode i have an error : ''Internal Parameter Error'' which appears after i flash the program to the board and run debug mode. I have full erase the H745 MCU using ST Link Utility but when i retry the same error appears unfortunately.
When i run the program in Debug Mode, i find in the command window this error :
''Internal parameter error''
''MapMem - map size truncated to 128MB''
Do you have any solution to solve this ?
Thank you so much Sir.
