Hello!
I am new in this forum but I hope anyone can help me! I am using the KEIL uVision4 V4.71.2.0 with Toolchain MDK-ARM Professional Version: 4.71.0.0. My hardware is the MCBSTM32F200 development board.
I want to use the USB example from the realime library (mass storage device example) located in C:\Keil\ARM\Boards\Keil\MCBSTM32F200\RL\USB\Host\MSD_File.
When I start the example all seems to be OK. I connect a USB stick to the USB FS (full speed) connector and I can operate with the files which are stored on it via the COM Port. The big problem is when I connect the USB stick to the USB HS (high speed) port. Of course I enabled the HS Mode via Jumper 2 on the board. When I connect an USB stick the program recognizes that a USB device is connected but when I, for example, want to list the stored files I receive the message that no files are on the storage. It is also impossible to format the device --> Formatting failed.
Has anybody an idea whats wrong? Is it neccessary to configure the example program to high speed mode in the source?
