Do you use custom carrier board?

Yes,we use our customized board, after the device enter fastboot mode ,it cann’t quit again.
What is the probable reason？Have you ever had similar problems？

The fastboot is generally triggered by the power button event. As you can see the log says.

0005.587] failed to init xhci or no usb device attached
[0008.595] Power button long press detected
[0008.599] Entering fastboot mode…
[0008.602] starting fastboot mode
[0008.607] fastboot cmd_init done.
[0008.610] platform does not support off-mode-charge

Please check if your hardware design is matching the design guide and power button is not pressed during cboot running.
