USBH and GUI thread problem (from Keil examples)

Ali

I am currently working on http://www.keil.com/appnotes/docs/apnt_268.asp example and stuck at stage 3 and 4. The MC doesn't start GUI thread and when I plug in a USB the os_error is called. How can I solve this? What's wrong?

    The SDRAM initialization in the project was not correct.

    I used the "system_stm32f4xx.c" out of the example "emWin example (STM32F429I Discovery) to get it working.
    The "system_stm32f4xx.c" from this example project has an adapted SDRAM initialization, not present in a standard generated project.
