We built our own boards using FX3. I connected my PC and FX3 via USB, but the driver won't come up to my PC. The circuit diagram is the same because it is referenced to the EVM board. PMODE is set to USB Boot. I know that romboot is basically in there. Why can't the USB side connect? I checked the power supply. The 19.2 MHz clock does not work because the USB is not plugged in.

No, the crystal circuit is required to provide clock to FX3 and then FX3 could work on that.

Looks like the clock circuit doesn't work as expected. Could you please check it on your side?
