Hi All,
I am using a MCBSTM32E evaluation board. I wanted to run the USBMEM sample code on the board, which uses the micro-controller's internal RAM as a USB mass storage device.
I followed the instruction in the Abstract.exe file to put a jumper cross Vusb and PB14 on the board. When I plugged the evaluation board to my PC. The USB interface is correctly enumerated and a removable disk icon is displayed in the Window File explorer. I am using windows XP Service Pack 3.
The problem is the driver has zero bytes. I cannot see the predefined Disimage file in the drive. I cannot move any files into the driver either. The LED PB8 is always on indicating a read event. Does anyone have the same problem? Any help will be appreciated. Thanks in advance.
