Hello,

I just receive my STM32F4DISCOVERY. I installed IAR EWARM, and ST-Link driver V2. But after several tests on two laptops, I am unable to link the discovery board with ST-Link.

This is the message displayed: ''Fatal error - ST-Link connection error Session aborded!''

And this is the message on ST-Link utility: ''No ST-Link detected''

Do you have any idea of what happened? Thanks!

Ok I find the problem! IAR provided the ST-Link V2 driver, but it's not the latest version and it is not compactible with Windows Seven... Download ST-Link V2 driver on ST.com !
