The problem when first power on my new PCB of FX3
We have made a new FX3 PCB based on the EVB, but we have met a problem, when I power up the board, the output power voltage are all right, at the begin of power out, the Crystal can output 19.2MHz clock, but soon the clock will miss, and I have tried to press the reset button, the clock will appear again, but when I release the button, clock will miss again. So my computer also can find the USB device too.
I also think may be the power have some problem, so I used the power from EVB to my board, but have the same problem.
Who ever have met the problem,I think I need some help.
