Hi freescale:

 

I have a usb download issue about IMX6QP platform(android L5.1.1).

When I downloaded bootimg using fastboot. PC fastboot's results are both ok. But If usb interface is EHCI, kernel can bootup. If usb interface is XHCI, kernel can't bootup.It's very strange.

Bellowed log is PC's dmegs:
