The errata documents for all PicoZeds have been updated. See v1.1 for the PicoZed 7010/20 and v1.4 for the PicoZed 7015/30 which are now posted on the PicoZed documentation page.
The Microchip USB3320 outlines very specific capacitance guidelines for setting the PHY mode to Host, Device, or OTG. To keep the PicoZed as flexible as possible, the Mode setting capacitors must be placed on the Carrier based on the operating USB mode the user requires. On Rev C, extra bypass capacitors were placed on the JX3 connector that may interfere with this mode setting.
