Hello! I did personal board with FX3 CYUSB3014. Connection with computer is via cable USB2.0. But chip CYUSB3014 is not shown in hardware monitor.
I think thhat problem can be in different voltages in VIOx. I use:
Is it correct? Or all VIOx must be the same: VIO1=VIO2=VIO3=VIO4=VIO5?
What can I view in addition?
Thanks for any answer!
VIO5 can operate at different voltage level than VIO1-4.
The enumeration issue can be because of a large mismatch in the trace lengths of USB lines.
You can refer to the FX3 Hardware design guidelines AppNote to make sure that the board design is correct:
