• Hellor,

    I really don't understand this issue. In the documentation of PicoCore MX8MN the pin Signal USB_PWR_A is mentioned as bidirectional.

    I I assume that this signal means VBUS.

    Further on the baseboard schematic, why the USB_HOST_PWR signal is not inverted as the signal USB_OTG_PWR because VBUS_DET pin of the usb hub USB2514 seems to be high-active.

    Thank you for reply.

    Best regards,


  • Hi,

    you are right, this pin is an output. We will correct the documentation. Thanks for the hint.

    The polarity of this pin is adjustable and it is active high by default. The USB_HOST_PWR is not inverted because the USB2514 VBUS_DET is active high.

    Best regards,
