Upgrade problem with STM32F4-Eval

I've a problem with my STM3240G-Eval board and my development tool chain. I use Atollic or Keil µVision demo. When I want debug my program or ST examples, the development software send me "Old ST-LINK firmware detected. Do you want to upgrade it?"
Then it opens the ST-Link Upgrade windows and when I click on Device Connect, the software send me "ST-Link is not in the DFU mode. Please restart it."
The problem is the same if I open directly STM32 ST-LINK Utility and I try the upgrade without Atollic debug.

But I don't know how to turn into the DFU mode, and where find the latest firmware.

Thanks in advance.


Config : STM3240G-EVAL not modified, USB cable between ST-LINK/V2 port and PC and/or USB-OTG-FS cable between board and PC, external power supply.
