External Interface activation problem on TX2 custom board

My new board was made by referring to the TX2 Development Kit C02 circuit.
after booting up, the HDMI screen is shown. but USB_VBUS_EN0, USB_VBUS_EN1 is disable.

So I compared my schematic and C02 schematic.
There is no TCA9539 in my circuit, C02 has it.
So, I tried removing the TCA9539 from the C02 board.
Similarly, the USB Enable signal is not activated.

How can I boot normally without using the TCA9539?

So, I tried removing the TCA9539 from the C02 board.

The power supply for usb is using the GPIO from that GPIO expander. If you don’t have it, you have to assign the correct GPIO for your board.

And the correct GPIO depends on your board design.

As for the software configuration, please read the TX2 adaptation guide published on 2019.
