Hi,

   

Which version of the SDK are you using? The Beta2 firmwares should work irrespective of the watchdog timer.

   

Please check on this.

Hi and thanks for answer  !

   

I have checked my PCB and all is fine. So I think, without CLKIN32, there is no way to enumerate on USB 2.0 Bus.
BEFORE i uploaded a RAM File to FX3 and first connect to Bus !  After this, i can configure it, but the first time ?
(I don't want to use a external 32Khz Clock ! )

   

With Clk32 all Applications works fine.

   

Best Regards
