Hello, a STR7 USB MassStorageExample for GCC can be found here: http://www.yagarto.de/projects/str7usbmsd/index.html The original STR7 USB MassStorageDevice (MSD) example can be found at the STMicroelectronics page. I have used this example only in the external RAM, but it should worked in ROM without the memory extension too. In this case, you have only 32KB of RAM. Best regards, Michael

I am attempting to use the original MSD example without any modifications. Some people suggested that my clock is not configured correctly? Thanks in advance
Hello Tamir, what kind of board you are using, a selfmade one? Do you have added a 48MHz clock for USB? Regards, Michael
