Nios I user logic problem

Hi everybody !

I'm using Nios I which I interfaced with a user-logic component in SOPC Builder. The problem is the following : once the user-logic component added in SOPC Builder, I can't program my Nios anymore in the SDK Shell because I have :

nios-run: Ready to download nios_prototype.flash over COM1: at 115200 bps

: Press CPU Reset (or CLEAR) on target board to begin download

: Type Control-C to exit the program

: Waiting for target......

But when I press on CLEAR it doesn't detect it at all (and it is the same if I program directly the Ram and not the Flash)

However, when I don't add the user-logic component in SOPC Builder and when I add it 'externally' to the Nios, it works, it detects the CLEAR button and it programs it !

What is even more strange is that the clear button and my user logic don't interact at all, they are not linked !

Please help me, i'm lost !
